hey peepz, does anyone know a good motor electricial in melb? preferably in the S.E region? sumting keep suckin my battery dry n its not hte lights, when i stick the key in the engine checks dont come on and im sick of having to pop the bonnet and disconnecting the terminals after i finish driving the car.... any help much appreciated

cheers n have a good one guyz

theyre auto elecs?

qualified mechanics and quslified auto elecs are very different.

working out what is sucking a battery dry is hardly rocket science.

the auto elec is going to do the same thing anyone else would!

Test the battery and the volatage to determine if its the alternator not charging or the battery having a crook cell or two.

it only gets tricky when there are way tomany things that run off the battery whilst the key is off ie computers,relays,globes,timers,cdplayers,cbs brake unit then all you can do is do a process of elimantion

with a current meter

thats after you have established alt and battery are fine

sounds to me like someone is volunteering a free job....

:)

ive seen it done to my car. Case of getting out the multimeter and hunting i think.

im not saying i could do it. But mates of mine have done it once or twice and they certainly a-grade mechanics, nice backyard job ;)

neither is plumbing but u dont hire a sparky to find a leak in your pipes do you?

sure he might be able to find the obvious ones... but what about the ones they cant find? do they charge for the time it took before they realised they couldnt find the problem?

this is why you recommend people go to the right type of qualified people.

Here's the process:

Check that the battery and alternator are doing their jobs. The battery should not be much more than 14V with engine running. If it's less, then the alternator needs attention. If it's more, and increases with revs, then the regulator (in the alternator) is stoofed.

Now, disconnect the +ve terminal from the battery. Connect an ammeter (multimeter set on Amps) between the +ve battery terminal and the +ve clamp. There should be a current flow indicated. Now start pulling fuses until the current suddenly drops. That gives you the circuit that is causing the problem. Now start disconnecting stuff on that circuit to find out which one is causing the problem.

A common cause of this problem is the light in the boot not turning off properly. Next would be the alarm, closely followed by the CD / radio (the battery backup of the settings). In combo with a faulty / old battery, any of these could drain the battery overnight.

Hope that helps.

thanks for the replies guys!

this is the first time ive read the thread as ive been so busy with work n all. ill try my hand at some of the advices with a multimeter first to see if i can diagnose the problem tho i doubt it due to my very poor electrical skills.

btw i had the battery changed the first time it went flat, 2nd and 3rd time was when the battery was a brand new item.

also if i could get the number for brighton auto electrics taht wud b nice

cheers n thanks for all the help

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
