SOURCE: 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.

SOURCE: I have a Coleman Powermate Pulse 1850 Generator.

Hi,
If the generator hasn't been used for awhile the rotor may have lost it's magnetism. All you need is to re-excite it. There are several websites that explain how to do this. It's a good place to start.

SOURCE: My Coleman Powermate 6250 generator has no power

Take the cover off and flash the rotor again with a 12 volt battery. Positive lead goes to the top or right side brush. Negative to the other brush. Just touch it on, then remove it, and check for power at plugs.
If that doesn't do it, change the AVR (voltage regulator)

SOURCE: no output voltage at all

The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...

The 220 outlet is only putting out power on one side


What brand of generator and KW? If you onlyone leg of the 22V it us not likely to be the voltage regulator aor rotor. Check to make sure that the voltage is checked right off the stator leads, where they feed the circuit breaker, and not on the load side of the circuit breaker, If you only have 120V on one of the 240V lines at that point, it is the stator winding.

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.

No AC out put


After working on several of this style coleman generator,i have found that the lead wires in the windings that are soldered to where your brushes would contact tend to break.I don't know if it's a poor design or just a fluke,i would check to see if your getting continuity on the rotor and go from there.They seem to either "burn off" or just break.

5250 running watts output on 220 side is 300 volts, 120 side is 175 volts what is wrong


I can't tell you what type of rotor excitation you have without the model number but,

If its capacitor excited then you have a bad capacitor(s). If it has a voltage regulator then it could be bad or the sensing wires going to it are bad. If the unit is not sensing proper voltage its going to increase excitation thus causing your units voltage to be to high.

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.

Running but putting out power


You need to remove the cover where the outlets are at and measure the voltage before the breaker. There are no fuses on the output side of the genset only breakers. If breaker is fine but still no output, try flashing the fields with a 12 volt battery. If voltage increases then your voltage regulator is bad.

Generator output


Hi, You don't say whether this is under load or not but if not is within the acceptable range, which is +/- 10% . Generally speaking, voltage on a generator is not the issue but the load which it will carry, hence their wattage ratings. Measure your household voltage and you will see that it varies from day to day but usually stays within the limits and your electrical panel is rated in amperage. Hope this answers your question!

67 votage display on 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.

Peace,
Carl

Generator wont put out enough voltage, only get 107 volts, is this a voltage reg. problem


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.
