Quoted from PAR:I Will continue to move down the line of other suspects unless someone would know why the D1 would test bad on installation?
Move on from this if you are talking about D1 on the MPU board. D1 measures .15V on the diode test when it is in the board, because of the circuit design. Has nothing to do with the F114 F115 issue.
D1 on the driver board is inline with BR1, for 20v, which then turns into 12v for the switch matrix.
Diode test BR1. I had an open diode on BR1 that caused a TOM that I just worked on Wednesday evening to have the F114 and F115 message. In my case, I still had 20v, but 12vreg was non-existent.
Quoted from PAR:I tested D1 and D2 Diodes, D2 was good, D1 was "Leaking"
Make sure you are using the diode test for testing diodes. Resistance test usually looks like a diode is leaking but in fact is a capacitor charging and discharging if you swap the leads around. Resistance test of a diode is only good for testing for a shorted diode.
