This problem is either that the engine RPM is too low (most likely), or that there is something amiss in the voltage regulation. Get yourself a DMM that measures Hz, plug it into the output and see if you get 61.5 Hz, if not look for the adjustment on the governor spring. On some Powermates this is a screw that pressed on the governor arm, on others it's a little tab the governor spring attaches to that you bend. Do this at no load. FWIW 61.5 Hz is also 3750 RPM of the engine.

I have a powermate 5000, it is putting out 330 volts on the 240 side/165 on the 120 side? what could be the cause of this?


There can be nothing but a bad voltage regulator in the end of the generator. They are getting harder to find. Robert

How do i remove the rotor on a powermate PM 0435001 generator


I have heard that you put a bolt in the end of the shaft and use a slide hammer to yank the shaft apart, There is a key, either flat or Woodruf to capture. Some use a length of chain around the bolt and a weight to yank it apart. Be prepared to catch it as it can destroy the windings. Definetly a two person operation.

I purchased a Coleman Powermate 5000 6 years ago: Ser: 94411583. Never really used it for any length of time. Kept for emergency. An electrician checked it for voltage output a short time ago. 240V...


Voltage is adjusted by raising or lowering the engine speed (governor adjustment), however one must also pay attention to the rpm because your generator was designed to produce 120 volts at 60 cycles while turning 3600 rpm. Your electrician should have tested for htz while testing for voltage. I would recommend re-testing under load and adjust governor to turn 60 cycles to see resulting voltage.

Hello. Plug something into your generator's receptacle, say a trouble light. Then check the output. With no load at all [nothing plugged in, you will get a voltage reading that is low. regards, Joe

I'm reading 130VAC on the output. Can this be


It should read 115v-120v with full load. Yes, you can slow the engine down just a little, depending on the engine, there will be a high rpm adjustment. 130v with full speed, no load, is really not too bad.

Three year old coleman 5000/6250 generator. High


Your RPM's are too high. There is no voltage regulator in coleman generators (generator is actually made by generac) and is 100% dependent on engine speed. There is a screw under the tank when your looking in from the recoil side. It controls the governor arm. Screw it in and it incresses the rpm, out decrease. Plug something in that draws a decent load while setting the rpms since you want it to put out 120 and 240 underload. Your idle voltage does not matter.

I have a Coleman Powermate 5000 / No power output


Two suggestions. One: check for voltage from the secondary coil wires (if it has one). Two: unless stated do not do this, I have always flashed the excitor circuit through the 120vac receptical. Give these a shoot and I hope it works for you.
