So I've been having some battery problems lately and i'm assuming it was brought on by my 2 new amps, subwoofers and all my new speakers....

So my problem is basically that my battery doesnt seem to be charging fast enough and/or provide enough juice to crank up my car after a short drive.

I got my battery and my alternator tested and was told that my alternator is sending just over enough current to the battery to get it charged at full load (a/c on, lights, music playing etc.) and the battery was also tested to be working(although i doubt that it's doing too well)

So my conclusion was that the battery just isnt holding up to the task and was looking at getting an optima yellowtop or maybe even a redtop if someone recommends that.

After looking at the optima website i realized that there are different sizes and they make a huge difference in weight and obviously have different power specifications.

I was looking at one of the smaller ones, the D51. Would this be sufficient for my needs? I'm not looking to run a HUGE stereo system for hours on end with the engine off. I just want to be able to drive along with my music on and not worry about wether or not the car will start the next time i try it.

Sorry for the long post, but i'd really appreciate the help.

This is what my current sound system consists of btw:

2 x JL audio 12" subs

JL 500/1 Mono amp

JL 300/4 amp

Alpine Type R 6.5" components

Alpine Type R 6x9's

I have a red top, could not be happier, only problem was that i had to trim off the little yabs at the bottom so it fitted in the factory location in my 33.

i believe mine is 1000cca, and turns it over dam fast so im assuming it will be more than enough, but the first thing you should be looking into is your alternator, when the car is running it is running off the alternator, should not be running off the battery at all, if the battery is going dead whilst you are driving you need to get a bigger alternator first.

how would i check that?

but i kinda doubt it, since most of the time when it happens the car can barely turn over for 3-5 seconds.... so it'd have to be taking up a HELL of a lotta current if the battery wasnt the problem

i have a yellow top and had to custom fit it into the existing location. i'm very happy with its performance until recently after not driving it for a week it died on me again. I decided that I'd install a kill switch between the battery and the fuse holder for all my amps so that when I know i wont be driving it for long periods i can take the switch out easily. Also this means people who have my car eg mechanic etc can't see what my system can handle as it wont work for them :laugh: Since installing the switch I've never had a problem again with the battery or any of the above posts mentioned problems. There's more on the optima stuff here: http://www.skylinesaustralia.com/forums/Au....html&st=40 page 3 near the bottom includes a pic of my battery install job.

cheers, shane

I'm running 4 gauge cable from the battery through a kill swith that i picked up from Jaycar for about $15bucks or so, then to a fuse box holder that holds four massive glass 60amp fuses. from the fuse box 3 cables run to each of my 3 amps and 1 cable off to the computer. no kill switch in, no nothing! and battery hasn't had a problem since. i even left the car for 3 weeks without clicking it over but it still turned no problems. dude...do it!

which red tops are you guys running?

i'm looking at these 2

and shanus, that sounds pretty cool, i might look into it.

so basically when do you hit the switch? when you park the car for a long time? wouldnt it be easyer to put a kill switch at the - wire for the battery?

huh? at the wire for the battery? not sure i follow

I have a number of massive cables coming direct off my yellow top optima battery.

1 of them goes to the original skyline stuff and fuse boxes and whatever,

1 I added on goes to my power converters for my screens,

and 1 I added also goes to this fuse box i was trying to explain. so yes, the kill switch is right near the battery in the boot.

Whenever I leave my car in the garage or at my parents for a long period of time I pull the switch out and leave it. I haven't needed to yet, but if i was ever going to drop my car off with someone i could so the same. otherwise it's cleaverly consealed behind one of my monitors in the boot that you reach around the back of to pull out push in, easy.

hope this helps. are you in melb? any cruises coming up soon i'd be happy to catch up...

cheers, Shane

I believe mine is the second one but it does not have the tabs on each end that i had to cut off.

I think he means just disconnect the battery all together, the problem with that is that you will have to reprogram your head unit and clock every time you start it again.

yes, that's what i meant, putting the kill switch at the negative cable, thus disconnecting the battery

reason i say that is because i wouldn't think that the amp would be the only thing that would possibly pull current from the battery over a long period....

one thing i wanted to ask... i have both my amps negative cables running directly to the battery. is that a big problem? could that be contributing to the issue?

And shanus, i'm about a 20 hour flight away from melbourne lol, dont think we'll be bumping into each other any time soon :(

lol fair enough

umm it's probably best to get a multimeter across your equipment to see whats going on and whats draining it the most. I haven't run the negative cables back to the battery directly from my amps as i've installed an earth block and all my negatives run back to this grounding unit which goes to the battery or chassis i can't remember which one. usually it's recommended to do what you have done, so i can't see how it's a problem, as long as you use the same gauge wire for positive and negative.

here's a shocking photo of some of the crap going on with my boot before i cleaned it all up. i now have office style condue keeping everything in line and power away from other wires etc it's really quite a neat job now :) You may notice how I've had to customise the battery tray and use the angle grinder to take off the original lips on the side, then just used a wider plastic base under the optima battery - geez it's tight! The three fuse boxes are all run back to the battery seperately, the one i mentioned in previous posts is the one in the middle, which has the kill switch now installed. and finally, just underneath this is where all my negative cables are.

If you can't find a solution by installing a kill switch, perhaps test it all and use some ideas from people on here. have you got two seperate positive cables to each amp, or do they go through a fuse box similar to mine? perhaps that's another idea you can steal if you have no luck...

sorry bout the long post, shanus

ive got seperate pos cables to each amp.

yea i would love to find out what may or may not be pulling electricity all the time but i dont have a multimeter.

i'm pretty damn sure it's my battery acting up though, biggest reason is because a couple of months ago my car was garaged for like 2 months because i had to work on my turbo manifold and i didnt disconnect the battery.

when i went to start it up, it was COMPLETELY dead, couldnt even turn on the brake lights.

After that, there was another time my car stood for 2-3 days after which the battery was dead once again....

and i noticed that it seemed to be going down hill from there...

the wierd thing is that Napa tested the battery and said that it's fine.... i'm thinking that maybe it's still producing the right amount of current but just wont charge beyond a certain level. Is that possible? Or is what i'm thinking flawed?

nah its not flawed, i was thinking on the same path when i decided to get a new battery. i didn't know why it just kept getting worse and worse, to a point where i brought a brand new battery and again, it died! i stuffed around a little and my mechanic told me it was my interior aftermarket light drawing current constantly so i got rid of it but it kept happening. rather than stuffing around anymore i just went that little bit further to get an optima battery.

'they say' whoever 'they' are, that unlike acid batteries that once flattened will half their life, then flattened again another limb gone etc etc until they're screwed, optima batteries are built to last a flattening. in fact, they strive off that stuff, as long as they get a full charge again when flat! IMO go the optima, you wont regret it!

never officially found out, but i'm 100% sure it were my amps and equipment as I've never had a problem since installing the switch so it can't be anything else!

split systems aren't too bad either, (you mean running 2 batteries?) but then theres housing the other battery and getting it going, and the problem is you still have acid batteries! its up to you man, good luck with the set up and make sure you post pictures when it's all in!!!

but didnt you say that you never actually flipped the switch yet?

so how could that have helped if you never actually used it yet?

on a side note, i had to jump start the car AGAIN just a few minutes ago, GOD is this annoying!

cant wait to get my new battery in, gonna order it by this weekend so it'll be here when i get back from my 2 week vacation

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
