oddcomp Posted March 23, 2004 Share Posted March 23, 2004 ok 87 gl-10 turbo recently on start up when its been sitting for a while all the idiot lights have a soft glow to them rev the engine a bit it goes away let off it comes back after a while it goes away compleatly until it sits for a few hours i am personally thinking its a crappy ground under the dash but i don't know wich grounds to look at first and since it the only car i ahve right now to get to work and back i can't have everything torn apart for a day or 2 to chase it pretty sure its not a ground under the hood since i just redid/added more about 3 weeks or more ago btw will a regular analog gauge cluster plug inplace of a digi gauge?

ShawnW Posted March 23, 2004 Share Posted March 23, 2004 Thats usually the diodes in the alternator starting to go south. Replace ALT asap to keep digi dash alive. Have the alt tested at a parts store to be sure. Some places even have on car testing for free. Quote Link to comment Share on other sites More sharing options...
oddcomp Posted March 23, 2004 Author Share Posted March 23, 2004 hmm the alts not that old.. but .. i have been giving jump starts to idiots .... perhaps its time to fabricate a bracket and just put a trusty chevy alternator on it.. or even this saab alternator better than 90 or so bux again Quote Link to comment Share on other sites More sharing options...
Cougar Posted March 23, 2004 Share Posted March 23, 2004 I agree with Shawn on this. Same thing happened with my alternator. These lights are in the field circuit to the alternator and it is a heads up warning about the alternator. They go out when you rev the engine because the alternators' output goes up also.

oddcomp Posted March 25, 2004 Author Share Posted March 25, 2004 interesting i yanked the alt and ac out at work last night had to wrestle with the 2 prong plug on the alt a bit got it out took off the ac so i had less crap in the way put it all back in minus ac and the problem went away... i am thinking corroded connectors on the alt?? still gonna do a gm conversion just not so high priority now Quote Link to comment Share on other sites More sharing options...
