Hey,

I have an R32 GTR, recently replaced the battery due to starting problems. This fixed the issue for a while but am having dramas again:

1. I started my car after work to drive home, it started fine but none of the electrics (tail lights, interior lights etc) worked for the entire drive home.

2. A couple of weeks ago i charged the battery and it started fine.

3. This weekend It started with the help of a jump start, however I tried it again today and it started but as soon as the leads were disconnected the car died.

4. I put the battery charger on the battery whilst in the car but it wouldnt charge at all, the light came on to say the charger is on but the charge light wouldn't light up.

5. I put the battery charger on the battery whilst out of the car and the charger said the battery is fully charged.

6. I've checked all the fuses and they are all good.

I'm thinking the alternator is probably stuffed and maybe even the new battery aswell. Any help would be greatly appreciated and if anyone has any auto sparkies they could recommend SOR.

Cheers.

I've had a battery charger tell me my battery is full a number of times but after a few hours it starts reading right (Flat) Same battery worked fine after charging it on and off for about 4 days (Slow charger)

And as far as I remember disconnecting the battery to see if the car runs on the alternator only works on old cars where the alternator is in a circuit with the ignition system or whatever.

I would never hook up a charger to any car with an ECU :-|

Point 1 usually indicates the accessory fuse under the dash, but you've said in point 6 they are all ok. Was it the fuses in the engine bay you checked or all of them?

Yeh mate I've only tried one charger, the charger has worked fine in the past, and worked ok on the missus' car. I've checked both engine bay and under dash fuses. All are good!

I'm thinking its the alternator, will take to an auto sparky on thursday. Anyone got any recommendations of an auto sparky or someone that will replace the alternator?

Cheers

Sounds like the alternator to me. The battery is probably dead, but the charger is reading false. I've had that happen before. Take the battery out of the car and put the charger on it over night. See what happens then. To test if the battery is dead, turn on all the lights and hold the horn down. If the horn fades to quietness, the battery is dead, if the horn keeps going, there is obviously charged. If the battery has no charge, blame the alternator :)

with all the lights and the horn going that will just drain the battery, a good battery shop should test the battery for you, if i were at my shop i would, although it is in kalgoorlie.

they'll have a battery tester that can test the cca (the guts) of the battery although your battery would need to have a full charge,

it's best to charge it on an automatic charger and leave the battery to float before you test it otherwise you'll get a false reading.

also depending on the size of the battery, the size of the charger and how discharged the battery is it will take more than a night.

i reckon it's the alternator

if the car dies after the jumper pack is disconnected its gonna be a bit hard to drive it somewhere lol.

option 1: ring anytime-towing for $100 and get it towed to a workshop.

option 2: check the charge rate while its running off the jumper pack, this should point u towards either alternator or battery

option 3: buy a new battery. Dont buy the cheapest battery from supershit either, just a normal heavy duty with caps that you can top up with water. Dont get a maintenance free battery as if you do have charging issues it wont do the battery any favours being constantly flat and recharged. If its not the battery at least you'll have a new one which'll make diagnosing easier.

btw your charger sounds fked, for anyone wanting to buy a battery charger i recommend a CTEK charger i got the 8amp one and it does everything and will fully charge a massive battery in under a day, can also leave it on charge for months without doing any harm.

    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
    • There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
