:bonkers:I sure hope some one can help.1995 STS 94000 miles.I have a no charge message.Volts at the battery are 13.6 to 14.2. I had the system checked twice.Bat and alt.check out good.I borowed a new bat.Same problem.I removed my alt. and had it rebuilt anyway.New brushes bearings and volt.reg. He said the diodes were good.Same problem.Car starts and runs great.Pulled codes p052h p109h p110h i052h.I also checked and cleaned all grounds.Also when i start the car all systems normal appears.About 15 seconds later no batt charge appears and i will also get an ocasional service susp.system but my main problem is the no charge.I tryed to clear all codes but i can't.Mabey i'm doing it wrong.Of course i had the batt disconnected when i removed the alt.Wouldn't that clear all codes? Thanks for any help and advice. Frank.
