actually, it sounds like the diodes are blown. Check our diodes.

As for checking stator, find the two wires, typically labeled L1 and L2 that are going to it. Measure with a multimeter. If there is no visual signs of damage, continuity can indicate a good stator. You should not have continuity between either wire and the stator frame.

The same goes for the rotor as well. The resistance measurements will not be the same for each one though.

Unfortunately, Powermate is out of business, and service information is scarce.

SOURCE: no output voltage at all

The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...

was the smoke from the two cycle engine or was it the windings in the generator electrically burning, have you checked your breaker on the unit?

SOURCE: I have a Coleman Powermate 5500 Generator. It is

This engine was not built with quiet in mind, it was built to be cheap. upgrading the exhaust is your best bet and likely the cheapest. Talk to a small engine shop about the possibility of using a muffler from an ATV.

Super Trap makes a fantastic muffler, if it will fit your application (most do). A link has been provided at the end. When you are looking at the various options, you will notice that a rating in db units. Reducing noise by 3db is half the original noise level.

if you can, go with the SuperTrapp. If still noisy (probably won't be), then add on the resonator as well. Downside to using aftermarket is that you will have an exhaust stack / system that sticks out the side of the generator. Upside is that you will be able to think quietly about how much the exhaust sticks out.

And no, I don't have any connection with Jack's, they are just the first hit that came up. Now that you know that something is available, you can do more research on it.

There are at least two AVRs for this generator. The original AVR has the diodes mounted on an external heat sink. The updated AVR has the diodes mounted directly on the circuit board. I have a schematic of the original model with the external diodes but it doesn't have the values or parts on the schematic. I will be more than happy to e-mail you a copy of what I have.

I just seperated the tapered crankshaft from the rotor of my coleman generator ( coleman powermate 2250 with a 5hp briggs and stratton engine). I applied PB blaster, and hit the end bell with a dead blow...


No there is not a key of any sort between the rotor and crankshaft, to verify you will not find a keyway to put one into on the shaft. Just the end bolt with washer holds it on.

Have you let it set for a long period? I have heard that if you do not use a generator that it will simply stop working(generator portion itself). Make sure no breakers are tripped and the wiring looks OK.
