I have a coleman powermate 5000 generator . Runs great but will not produce electricity. If it needs to be flashed ,how do i do that. I do show about 1.35 volts on meter at 110 plug in and on 220 plug . Thanks Alec
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.
