Angus Smart Posted October 30, 2006 Share Posted October 30, 2006 Car started fine at work! i got home. pulled up in the driveway. turned off car. opened roller door (electric door has had the dick for some reason) and went to start it again! and it was like i had no battery at all. got dads car out and jumpered it. got it inside the garage and left it run for a bit. turned it off.. tried to start again and the dash lights barely light up. i have a dry cell sealed battery which i have never ever had a power problem with. tho i did get it out of a car at my brothers work. so it is slightly second hand is there anything other than the battery that could be my problem?? Car be the 32 gtr Cheers Andrew Link to comment https://www.sau.com.au/forums/topic/141035-car-battery-electrical-problem-32-gtr/ Share on other sites More sharing options...
gtrchick Posted October 30, 2006 Share Posted October 30, 2006 possible alternator? Link to comment https://www.sau.com.au/forums/topic/141035-car-battery-electrical-problem-32-gtr/#findComment-2626489 Share on other sites More sharing options...
Beer Baron Posted October 30, 2006 Share Posted October 30, 2006 sounds like alternator to me. check the battery with the car off make sure it's ok, then check what the altenator is putting out when the car is running.

Angus Smart Posted October 30, 2006 Author Share Posted October 30, 2006 Battery reads 12.7 when turned off When i try to start now, I hear what i think is the fuel pump trying to kick over. and the dash lights are faded. but then they come alite and fuel pump kicks in for a second. then it goes all dim again.

Angus Smart Posted October 30, 2006 Author Share Posted October 30, 2006 (edited) ok now with what i'd say a shorting sound somewhere at the rear of the car above the fuel tank??? Thats the only way i can descrive the sound. Tho i think i usually hear it when its running good. cant quiet remember Edited October 30, 2006 by Angus Smart Link to comment https://www.sau.com.au/forums/topic/141035-car-battery-electrical-problem-32-gtr/#findComment-2626837 Share on other sites More sharing options...
tacker Posted October 30, 2006 Share Posted October 30, 2006 Bad earth i would say check that first, see what voltage you get between the + and somewhere on the body.

blind_elk Posted October 30, 2006 Share Posted October 30, 2006 There are any number of previous threads that describe how to test and evaluate these sorts of problems. My initial guess is a dead voltage regulator.

Angus Smart Posted October 30, 2006 Author Share Posted October 30, 2006 There are any number of previous threads that describe how to test and evaluate these sorts of problems.My initial guess is a dead voltage regulator. well generaly speaking. its alot easier to just ask. considering I DONT KNOW WHAT THE PROBLEM IS and to check for a dead voltage regulator is done how?

blur Posted October 30, 2006 Share Posted October 30, 2006 clean the battery terminals... check the voltage after the terminals while cranking ill bet you find a massive drop. if it was the alternator, the car would have cut out before you got home, and not continue running after you jump start it, and battery wouldnt show 12.7v either.

Yeah a massive drop is what i found! down to around 4 volts. i had battery on charge all night and tried to crank it in the morning. also with my jumper pack. which also seems it had the dick yesterday as it wouldnt charge up over night either. the battery terminals are very clean! its a dry cell battery so they dont really leak or get dirty. I didnt get to check the alternator. as i had to move too many cars around to be able to jump start it. This would have to be the first electrical problem i've had! the car hasnt missed a beat!

cowie165 Posted November 1, 2006 Share Posted November 1, 2006 You need ~10V to turn the motor. I had the same problem as you about six months ago. Battery was flat. It also read 12V static but you could see the drop on the voltmeter as you cranked it. PS You'll receive more help around here if you keep your cool.

arep3 Posted November 1, 2006 Share Posted November 1, 2006 sounds to me like the battery is dead. how old is it? try to find a letter and a number thats been burnt/melted into the top of it. example. L6 would be november 2006. letters are for the month except they dont use I cos it looks too much like a 1 A=jan B=Feb...H=Aug J=Jul etc Link to comment https://www.sau.com.au/forums/topic/141035-car-battery-electrical-problem-32-gtr/#findComment-2634479 Share on other sites More sharing options...
