jeffer949 Posted January 6, 2009 Share Posted January 6, 2009 Ok so i have been fighting a charging problem for about 2 weeks now. Ive replaced my battery my alternator and ive rewired the charging circuit so that its completely separate. Ive been going off of this diagram that i found on atlanticz.ca And here is a ruff diagram of what i have done exactly. It does not charge all the time though. When it does charge it charges at 14.6 volts pretty much all the time just not at idle and it comes down to like 13.5 i think. It seems to charge normally at first but if i let the revs come down and idle after a while it stops charging. and wont come back on. unless I turn my car off and start it again. Also i wouldnt say its not charging at all its just not giving a full charge. It normally will stay around 12v's ish but very slowly drop and this is at night with lights, heater, wipers all on and running My MSNS. And it did this for at least 85 miles the past 2 days. but the battery was down to about 11volts last night when i checked when i got home. On the circuit above i have the switch and the light going to the L post. I put the switch in there because i wasnt sure which way was correct to wire it up. So which is the correct way? Ive read some stuff on the GM 10SI alternators that say you need a resistor inline to the L post to give it an initial load. Do you think i need that or is the lamp good enough? Im at a loss hear. Any help would be appreciated. Im sick of having to charge my battery every day to get to work and keeping an extra batter in the back just in case.

jeffer949 Posted January 6, 2009 Author Share Posted January 6, 2009 WOW im an idiot. My belt was slipping. hence why it would charge when it was cold and then when it would warm up the belt would start slipping and stop working. I was out of adjustment so i went and got a new belt that was a size smaller. i think it was a 17340 instead of the 17350 that is for the car. I think part of this has to do with the fact that i have the professional products dampener from MSA and its has a smaller diameter so i couldnt get my belt tight enough. And on the switch i installed It is supposed to be closed all the time if any body reads this. So basically you dont even need it there.
