Well, I've done some trouble shooting. This is what I have done.
I checked the Progressive Dynamics Converter/Charger (PD9260) and everything seemed to be fine.
I ran the generator, and the powerline display did not change. The display did not even show the GenSet as on and the 50 amp LED did not change (still on 50 amp). In the past when the GenSet was on, the amp usage light showed the amps being used.
I checked for voltage going to the display, I did find some dc voltage. I have been assuming the voltage to the display was OK because I've been getting LEDs.
I switched the selector switch from Powercord to Generator with no change to the display.
I'm beginning to think the circuit board has gone out. Any ideas where I might get another board? Any idea what a fair price for a new board might be?
