There is one diode on the power module that did raise an eyebrow. I shall check my notes, and inspect the module again tomorrow. As I mentioned earlier the FBT ring test passed, HOT is good. Will update you later.

FC901, 5amp GMA. I traced that to bad regulator at IC951. After doing reg. replacement. Set Power LED blinks twice, you here relay click. It's not blowing fuse FC901 but I need to know the 2 blink code. Can ring the FBT no problems. Some type of shutdown error I guess. Anyway, I have no service literature, input from tech with access to manual would be appreciated.
