Does anyone have or know where I can get a copy of the charge circuit? My alternator's duty cycle is controlled by a wire to the ECM from what it looks like. I think there is a problem here as all other connections test good, fuses checked out, etc. I originally thought it was the alternator as there was not current getting to the battery, so I removed it and had it checked out, figuring I would warranty it and be done. But it passed with flying colors apparently, so I proceeding to do some digging. Anyway, long story short I need a schematic... Anyone?


Thanks.

Hmm. How is the battery? Are the cables corroded, connections loose? Is the main ground corroded?
Just somewhere to start which you may have already done.
