Good Evening,

After brush replacement and then subsequently alternator replacement, it seems that the problem with the charging circuit is now presumed to be w an open warning light circuit.

From some research on the brick board it is likely that a microcrack has developed in the instrument warning light circuit board. To be clear, w key on position 2, only the SRS and seatbelt light are energized. Further, sometimes, but not always, a deft tap on the dash will make magic and the 7 other idiot lights will lite.

From what I understand the alternator will self excite at a high RPM. Is this true regardless of the status of that warning light circuit?

Thanks for your thoughts

Marty
