Powermate generator PM612023 runs but no power. I fed house power back thru the generator while the generator was off. I heard a pop and now i have no power. What did I blow?

Hi Have you tested the voltage output from the generator outlets.

How are you connecting to house power?


possible power spike

Take the through bolt out of the end of the alternator / rotor shaft. it is a long bolt. The shaft from the engine is tapered and unlikely to just pop off. Find a bolt that will screw into the end of the rotor shaft (hardend) find a metal bar that will slide into the rotor long enough so the bolt tightens down on the bar, it will pop the alternator off the tapered shaft

I wouldn't recommend modifying the muffler, doing so would change the OEM's engine back pressure specifications and can lead to engine damage and carbon monoxide leakage

Hi,
Yes, you killed the diodes in the generator...they can be replaced by a generator repair shop... happens all the time...

Extension cord will cause it to trip. Make sure it's big enough and as short as can be. worn breaker will trip easier.

it sounds alot like it is producing alot more power than 120 volts per leg you should really only have plus or minus 10 percent of that voltage anymore will blow lights check voltage output with meter, if voltage is high may have problem with voltage regulator and it may need be replaced. I assume that not all of the lights in the house are on the same circuit therfore not on the same leg of the generator so is probably only one leg of generated power to high there for only blowing some of the lights

Where can i obtain a manual for the 5500 gas generator

You will need to install new diodes,they are located in the plastic housing behind the receptacles...It looks like little spark plugs..They work to put dc voltage to the rotor,without the exciter voltage applied,you will not get ac power out..The part number is 3483.01....You can buy these online for about $6 each,they have 2 inside the generator,and you should change both.

Here is a simple test to check field and other wiring. With engine off apply 12v ac 1 amp to 110v outlet plug on generator. This will energize the field windings and should cause the armature to produce dc voltage at the brushes and produce a nice magnet. If there is a short in the field or broken wire or shorted capacitor there will be no dc reading at the brushes. . This test is the opposite of what actually occurs when the engine is running. That is the armature produces a magnet fed thru the windings, regulator and brushes. If dc voltage is present at the burshes, remove 12v ac and start engine to check for output. enjoy
