carlightsup Posted March 24, 2012 Share Posted March 24, 2012 Hey guys i decided to go for a drive in my 32 last night, i hadn't driven it for a week and it has developed some strange issues; the HIDs were flickering on and off, and the power steering was cutting out and there was a high pitch buzz coming through the speakers. the only thing i have done to the car recently was put new coil packs in and re gapped the spark plugs, but that was 3 weeks ago and it was running fine until now... I know its hard with electrical fault but i was just wondering if any of you have come across this before or you have any suggestions for me?

Anfanee Posted March 24, 2012 Share Posted March 24, 2012 try checking an earth near where you did the work. you could have bumped it and when you drive the earth is breaking itself lol. thats all that jumps to my mind.

carlightsup Posted March 24, 2012 Author Share Posted March 24, 2012 Yea unless there is one under the valley cover i forgot about the only earth i would have touched would be the one on the ignition pack, which seems fine... but i just went and double checked it and the car has lost all power now, the battery is still nice and tight and reasonabley new, so i guess ill have to pull the multi meter out tomorrow.

Anfanee Posted March 24, 2012 Share Posted March 24, 2012 sounds like an earth problem then. sorry to break it further lol Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6288346 Share on other sites More sharing options...

carlightsup Posted March 27, 2012 Author Share Posted March 27, 2012 So yesterday i tested the battery and found that when its disconnected it has approx 12.04v then when i hook it up it drops right down to 2.01v... i tried disconnecting the HIDs, audio system and coil packs one at a time with no change in voltage (they are the only aftermarket electrics in the car) so my thoughts are there may be a short somewhere?

zebra Posted March 27, 2012 Share Posted March 27, 2012 Tried a new battery? Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6291501 Share on other sites More sharing options...
carlightsup Posted March 27, 2012 Author Share Posted March 27, 2012 I put a new battery in about 3 month ago.. but this one may be rooted because i know my amp was killing the battery (i took that out a few weeks back) i just thought if the battery was gone it would have had more trouble starting when i first noticed the issues with the headlights and power steering... And there seem to be something drawing way to much current anyway coz it drops 10v when i hook it up... but ill see if i can borrow a healthy battery from one of my mates and see what happens Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6291695 Share on other sites More sharing options...
D.I.Y. Mik Posted March 27, 2012 Share Posted March 27, 2012 Try pulling out all fuses and relays first, then put em back one by one. At least it might narrow it down a bit.

carlightsup Posted March 27, 2012 Author Share Posted March 27, 2012 Yea i tried that and had no notable change.. I went and got a battery print out this afternoon and it said "charge system failure" so looks like an alternator.. im told that they can collapse and the internals can touch together which could be causing the drop in voltage..

Sinista32 Posted March 27, 2012 Share Posted March 27, 2012 sounds more than plausible. I think Zebdrew had a recent experience with a failed altenator in his MKIII supra. Strange things happend to it too! Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6292149 Share on other sites More sharing options...
zebra Posted March 27, 2012 Share Posted March 27, 2012 Was a starter. Nearly melted the multimeter when trying to start it was drawing so much current lol Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6292157 Share on other sites More sharing options...
carlightsup Posted March 27, 2012 Author Share Posted March 27, 2012 lol... Well after charging the battery the car starts fine.. so tomorrow ill hook the multimeter up while the cars running and see if the volts are going up or down.

RS4-S Posted March 27, 2012 Share Posted March 27, 2012 If you put a volt meter over ya battery with the engine running you should see 13.6 - 14.4v, if you only see 12ish volts then alternator/wiring is the issue Link to comment https://www.sau.com.au/forums/topic/395795-r32-gtst-electrical-problems/#findComment-6292369 Share on other sites More sharing options...
D.I.Y. Mik Posted March 27, 2012 Share Posted March 27, 2012 So if the alternator is no good..Usually the diodes fry in the alternator, its easy to check them and cheap to fix, like $4.

carlightsup Posted March 28, 2012 Author Share Posted March 28, 2012 My battery ran flat again so its on charge now and ill test to see if the atlernnator is charging the battery this arvo. Mik, is it easy to explain how to test the diodes?

carlightsup Posted March 28, 2012 Author Share Posted March 28, 2012 So i fully charged the battery and started up the car with a multi meter hooked up to the battery; started out at about 12.8 volts and dropped down to 12.2 as the car reached operating temperature.. when i reved the engine the reading went up to 13.2, so the alternator seems to be charging the battery. i turned on the headlights ac and radio and the volts dropped to 11.65.. i took the car for a drive and re tested the battery and nothing changed.

carlightsup Posted April 2, 2012 Author Share Posted April 2, 2012 I changed the alternator and fully recharged the battery yesterday and everything seems to be working as it should now... thanks everyone for your help with this i really appreciate it!
