Default Coleman Powermate PM0535202.01 Capacitor Frying

I have a Coleman Powermate PM0535202.01 with a Briggs and Stratton 185432-0606-e1 engine. Was reading 2 volts under no load. I found the old capacitor bulging and the diodes severely rusted. I replaced the capacitor (POWERMATE CAPACITOR 220UF 200V.HD 85 C - (0034819.01)), both diodes, put in new brushes. Ohm reading on the slip ring was about 37.6 ohms.

I polarized the generator with a 12 v battery charger. I read a voltage on the voltage meter been 109-130 volts at the brushes very unstable, but was not getting power at the plugs. I switched over to 600v scale and saw 219-300 volts. I took it apart and cleaned the slip ring with 400 grit and wiped with mineral spirits. After running it again the new capacitor fried as in boiled with lots of smoke and melted the wrapper and spitted fluid. The wiring connections look good.

What is causing the new capacitor to fail?

I reinstalled the old slightly bulged capacitor and adjusted the two screws that control governor to give 120 at the outlets under no load and 155 volts at the brushes. I don't know what was wrong with the new capacitor. I did notice the old capacitor had a green dot one terminal and there is a green wire. Are they polarity sensitive?

Searching that particular part number: Yes, most emphatically polarity sensitive! Notice black strip on one side of sleeve? That is an electrolytic capacitor. They typically blow up if connected backwards.

".....adjusted the two screws that control governor to give 120 at the outlets ….

Governor should only be adjusted to set the frequency, not the voltage. Typically, these little units should be set to show no more than 62 Hz at no load and not less than 58 Hz at full load.
All other things being within spec, this should give you proper voltage at the outlets.

Page 2 post #12 I gave the specs for the Coleman Generators. They are all pretty close in design and operation. https://www.smokstak.com/forum/showt...=178396&page=2

Mine runs above 143 volts no load at 63HZ. These units can go to 140 Volts no load. Most of them have no active regulation. Some do though.

I wouldnt worry too much about no load HZ so long as loaded HZ is within spec (not less than 57, not more than 60.2) typically full load hz should be around 58-59 depending on how well the engine can carry the load.
