Hi guys,

I've come upon a bit of a snag..since I bought my skyline, I've been wanting to give DIY a go and since I stuffed the CD player in it the other day, I thought I'd try installing a new one..well, I did but here's my problem:

after I installed it, when I switched the ignition to the ACC position, it worked but then I switched it off and to ACC again, and it stopped working!

Then, the car wouldn't start, then the door open and key in ignition chime went crazy, then didn't work altogether!

Then the interior ceiling lights didn't work..I am pretty new to all this so I was wondering if anyone had any pointers??

Cheers

did the car start BEFORE you played with the stereo. how long did you have the doors open? 20-30 minutes on a crap battery will cause this. as for fuses - both are under the dash.

did you chop the radio plug off?

series one or series 2?

need more info really.

thanks for the help so far guys, I've re-attached my ground lead instead of using the existing one and so far I seem to be getting better results, now when I switch to Acc position, the head unit and all associated electrical equipment (ie interior lighting, hazards, front park lights, tail lights, etc) work as well and consistantly..but the engine is still not turning over!! The dash lights come on and I hear this "click" sound as it tries to start or something but just can, then all the dash lights just die..what have I done to my baby ;)

my battery still reads 12.7V or something while the stuff is running so that's ok. I can't belive it but I've spent the whole of yesterday and a few hours of today too..saw king kong by the way gotta say I quite enjoyed it..

Anyway, it's a series 1, GTS25T I had the doors open I'd say upwards of a few hours but while I'm working on it I always disconnect the (-ve) terminal on the battery which will protect against shorts...and serves to perform an ECU reset if I'm correct..is there any special way to start it up after ECU reset?? WTF is going on with my car?!

Its the battery thats gone flat.

The clicking you hear is the pull in winding on the starter motor disconnecting because their is not enough current to hold it in, because the battery is flat.

Jump start it and all your problems will be solved.

It doesnt matter what voltage your turbo timer is showing the battery has because the battery isn't under load...

hey thanks for the help fellas!

Guess what..day before yesterday, I had given up and I thought may as well get it towed or get an auto electrician to come out. Then luckily my mum asks me to get something from the garage and just out of the blue I thought, "why not?" and I decided to try starting it...

I could hardly belive the next few seconds..the engine started and I was wide eyed and cheering! I couldn't belive it...and I still don't know exactly what's going on.

I think MANWHOR3/Mr Italy! were on the right track though 'cause on xmas day I tried again, and I re-grounded with my own, instead of using the existing one. Then, I used a multimeter to measure the battery directly at it's terminals with the key turned to the Acc position with the stereo on (which worked but just didn't start) then measured it at the wiring when my stereo was connected..then when I tried to start the car, there would always be a huge voltage drop which never returned to the normal level until I disconnected the -ve terminal on the battery and reattached it after a few seconds.

oh well...I'm just happy it works now..

happy new year fellas :P

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.

      Not required but appreciated. Super Coppermix Twin even the non-competition model feels like the pedal is noticeably heavier than stock which was pretty well judged IMO. I'll be swapping in the Nismo operating cylinder soon to see how that feels.  Personally I haven't felt anything that justifies replacing the damping loop, at least compared to more modern stuff where the clutch delay valve is actually quite noticeable.
