jdcutty Posted September 13, 2005 Report Share Posted September 13, 2005 My voltage seems to be really low. Even when not at idle, my voltage (with nothing running) is just below the 13v indicator, which isn't what concerns me. At night, with the headlights on it shows maybe around 11-11.5v. Sometimes with my amp on it drops low enough to trip on the ABS light. I am just need to know if anyone else has/have had these problems and what caused it. I may have burned a diode in the alt by putting such a strain on it, but if anyone else has suggestion that could help, it is greatly apprecitated.

gp90se Posted September 13, 2005 Report Share Posted September 13, 2005 if you have a local autozone, have them load test the alt. its free and takes 2 minutes Quote Link to comment Share on other sites More sharing options...
1990lumina Posted September 13, 2005 Report Share Posted September 13, 2005 I'd say your alternator is tired. If you need to replace it though, STAY AWAY FROM BOSCH! Piece of shit alternators!! I bought one with 5 year warantee and in winter time at idle with the lights on, the f'in dashlights dim out and other crazy stuff, then if you rev it slightly it all returns to normal. My old tired Delco didn't do that....just incase you need to replace yours I'd just say stay away from said company above. Quote Link to comment Share on other sites More sharing options...
jdcutty Posted September 13, 2005 Author Report Share Posted September 13, 2005 The thing is, I was told by the dealer when i bought it, that he had it replaced when he got it cause it didn't seem to be charging too well. This leads me to believe that it could be something else. I had it tested back in may or so and everthing came out ok. I will be replacing the worn serpentine belt soon, i will have to see if that makes any difference, as if it were slipping a little. Quote Link to comment Share on other sites More sharing options...
mfewtrail Posted September 13, 2005 Report Share Posted September 13, 2005 Check for loose connections or corrosion on all your main power and ground cables while you're at it. Also, are you going by the voltage gauge in the car or checking the voltage with a voltmeter/multimeter? Quote Link to comment Share on other sites More sharing options...
jdcutty Posted September 13, 2005 Author Report Share Posted September 13, 2005 I am going by the gauge in the car. I have not yet got under the car and check for corrosion on those connections, but the ones up top are good. It prolly doesn't help that the plastic on my aux battery post is cracked.

jeremy Posted September 13, 2005 Report Share Posted September 13, 2005 sounds like an alternator on the way out. Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted September 13, 2005 Report Share Posted September 13, 2005 most if the time Im running around 13. or 13.8 volts, but then again thats with my stereo too. But I agree with jeremy Quote Link to comment Share on other sites More sharing options...
94CutlassSLCoupe Posted September 13, 2005 Report Share Posted September 13, 2005 Mine does that too...at night with the A/C, cooling fans, radio, and headlghts on it goes down to 12.8V or so (my gauge looks just like you describe) but the readout i gave is from my DIS. Most of the time its between 13.1-13.7v Quote Link to comment Share on other sites More sharing options...
jdcutty Posted September 14, 2005 Author Report Share Posted September 14, 2005 I guess I will just have to wait and see what happens. BTW, Pat, it looks like I will be around flint for b-section as my co-op employer decided that they want to keep the graduate that they had instead of me coming back. And they couldn't even call and tell me, assholes. Quote Link to comment Share on other sites More sharing options...

Lee Posted September 14, 2005 Report Share Posted September 14, 2005 mine normally runs three bars but when it's hot out it will drop down to 2 or 1 bar. Strangely, if I turn on the parking lights it will come back up one bar. What would that mean? Been curious a long time. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted September 14, 2005 Report Share Posted September 14, 2005 Quick side note. Is there a rough idle on anyone in this threads car? Cause My van had the same issue, and it wasnt power related, vacuum hose was broke..cause a rough idle, dimming lights and bad headlights Quote Link to comment Share on other sites More sharing options...
jdcutty Posted September 15, 2005 Author Report Share Posted September 15, 2005 No rough idle, car runs perfectly, I make sure of that at all my cars. Quote Link to comment Share on other sites More sharing options...
LumiDriver Posted September 15, 2005 Report Share Posted September 15, 2005 ok then prolly its a tired alt..Only thing I could think of. Also, check your belts too, maybe its not spinnign the alt fast enough because the belt is slipping, but not squealing. Quote Link to comment Share on other sites More sharing options...
