Coleman Powermate portable Generator

[NTLBM]

ok the motor is kawasaki gas engine it starts and runs, but no electric output to the 120v plugs this is an older generator and has sat for a while,::: any input on this would be helpfull

If the generator is NOT an inverter-based unit, it probably needs to be flashed. The metal core of the generator can lose its magnetic field over time and then can't produce electricity.
Without a manaul for your generator, I can't give you a guaranteed procedure, but you might try connecting 12 volts DC to the AC output receptacle of the generator while it's off The term "flash" means just that - you only need to brush the wire across a battery terminal long enough to see the spark.

No guarantees - some generators require partial disassembly to get to the correct terminals for flashing.

was unable to find auser manual anywhere they do not exist anymore, found out it is brushless does not have brushes I tried to flash the jenset by useing a double male plug from generator to a 115 house plug however that did turn on the droplight I had pluged into the generator while it was backflowed but did not repolarize it ,,,,, So i believe it hat bad Diods or Rotor damage thanks for all the feedback
