High voltage? I have a Coleman Powermate model PM0525300.19 that runs great but puts out 152 volts AC. What part do I need to replace to get the voltage down to the 120 volts level? Thanks!

SOURCE: Runs great but will not produce electricity

To flash the excitor circuit on a coleman ( the generator is built by generac) you need a 12 volt battery. You quickly apply 12 volts via your 120vac recepticals. NO MORE THAN ONE OR TWO SECONDS! Then check you ac voltage. Most of the time the brushes are burnt up when voltage is low. Check the brushes first. You can access them by taking the end cap off of the generator via two to four screws. The brush holder is easy to spot, two wires leading to the front of the amature. Hope this solves your problem.

Hi,
If the generator hasn't been used for awhile the rotor may have lost it's magnetism. All you need is to re-excite it. There are several websites that explain how to do this. It's a good place to start.

set at 3600 rpms at 60hz

There are basically 2 possibilities that can cause this.

1) Enigne RPMs are too low. but, since you already played with the throttle, this probably isn't the case. RPMs should be about 3600 though.

2) The voltage regulator / capacitor has high ESR (resistance) or is bad altogether. Replace.

After working on several of this style coleman generator,i have found that the lead wires in the windings that are soldered to where your brushes would contact tend to break.I don't know if it's a poor design or just a fluke,i would check to see if your getting continuity on the rotor and go from there.They seem to either "burn off" or just break.
