Just got a schematic from Pramac - current owner of the Powermate brand.
It's an Italian company. Homelite owned the brand for a while.

Sort of threw me when I looked at the schematic. PWR1 and PWR2 windings are
the output of the generator (110/220V). AVR is the Automatic Voltage
Regulator which may be part of the problem. EX1/EX2 look to be part of the
stator and provide AC to the rectifier / Cap which in turn feeds DC to the
AVR module. Would guess that the field winding (armature) is the coil marked
+/- at the bottom. Not shown but it is fed by brushes. This is not a
brushless generator.

"Module I.C." is the automatic Idle control that drops engine to idle when
there is no load. Commonly used on construction sites when driving only one
large tool.


============
Need to troubleshoot a broken generator.
Powermate Vertex 7500W
Model PM0557523.9

Found owner's manual and parts list but no schematic / wiring diagram.

Anybody have some resources? The usual googling just gave me more of the
same. Tried re-exciting the field to no avail. lead had come off of the
capacitor and looks to have been sparking against something. Trying to make
sense of what might have failed.
