R33 Wont Start, Try To Start And Electrics Die...

[benny bobo]

Hey,

Got an electrical issue i think with my car (r33 gtst S2 sedan - auto).

Was about to leave work today (Varsity Lakes), went to start the car.. starter motor just ticked like battery was discharged..

Tried jump starting (off a running car), left it charging for 10 - 15 min, wouldnt start.. So I gave up and got a lift to the Pub.

Finished at the pub, Got a new battery (9cell 270cca, same as before but new), installed it.

Power works fine in ACC (Stereo works), but as soon as I turn it to ON (Not Start) the electrics die.. turning to START does nothing. When i leave it on start, the negative terminal gets extremely hot after a couple min... im guessing a short

Please, does anyone know what the problem most likely will be, or where to start looking?

That sounds like a bad earth off the chassis to the -ve terminal. Find where the -ve cable is bolted to the body, and clean up the connection.

It did have a fair amount of crap on it, cleaned it a bit with some hot water and gave it a bit of a wiggle too..

It seemed like that was the problem..

Could a bad negative ground connection drain a battery over a few hours?

It won't cause the battery to discharge, it will prevent the battery being proper re-charged.

initial problem sounds like you left it in D and tried to start it

Funny you should mention this, I had the exact same thing happen with my 33 yesterday.

Had been driving all weekend, wife took it to the shops came back 30 mins later and it would attempt to turn over but couldn't fully crank.

Checked the voltage and the battery had drained itself. (nothing was left on in the car). Pulled the battery put it on charge for a few hours, put it back in, started no problems at all. Checked for voltage drain and there is none.. just bizarre..
