Certainly would appreciate your professional guidance. The generator Q55 ( Model 09592-3 Serial 307-1784 5500 Watts) fails intermittently, failure mode is no red light and noAC output.
Thus far I have found the following:
When unit is functional, the resistance between V/R pin 3 ( third pin down) to ground is about 20 ohms and when not working the resistance is 380 ohms.
If I briefly apply 12v to pin 3 the red light will illuminate briefly, will not stay on.
The boost appears to be working, it will jump to about 6 to 8 volts then down to zero.
Very intermittent, it may work fine and very next start it would fail again! Sometimes I can start and stop the generator 6 or maybe 8 times in a day and it will work properly about 50% of the time. Bad Brushes? Unit has 700 hours on it.
Any advice?
Thanks in advance for your help.
Best Regards, James
