Question about Coleman Powermate Powermate 5000W Generator
Thanks for reponse.I'm in KSA.We have cummins 3 phase generator.according to your instruction i have checked now 67 votage display on the generator output.
Please stop making new problem threads each time you answer, instead post a comment to one of the 5 threads you already have open for this problem. It's getting hard to follow the conversation :-)
OK, now to the problem. You say you have checked 67 volts is displayed on the generator output, I think this means that you see 67 volts on the control panel display when the generator is running. This can be several different problems:
a) a bad CT/PT module that tells the controller the wrong voltage
b) a bad A/D module inside the controller itself
c) a bad voltage regulator
Get a real DMM meter and measure the voltages at the top side of the output (large) circuit breaker of the generator. Put the black lead of the meter on the neutral wire and then measure to each of the phase wires on the circuit breaker. If you get normal voltages then you probably have a bad A/D, if you get 67 volts on all 3 phases you have some other problem.
You still haven't told me what model/spec of generator this is, look on the data sticker on the generator cabinet.
