Question about Coleman Powermate Powermate 5000W Generator

1 Answer

Low voltage generator output

I have a 10000 watt honda/master generator. Because of the ice storm here in Arkansas, I fired up my generator, and after 2 hours it shut down. I took it in to be serviced, and was shown the broken cam shaft! I had the generator repaired and took it home. For some reason I can only get 88 volts tops whether there's a load on it or not. The serviceman claimed he plugged a drill into it and said everything checked out in the shop. My generator is 10 years old and has 27 hours on it. Would transporting it home down a bumpy dirt road possibly break something enough to only produce 88 volts?

    Hz is 62 but voltage is 85 on the 120v side and 175 on the 230v side.

    Hi, This genset has dual windings. So you should get something different from a 120 plug than you get from a 240 plug, so where you are measuring your voltage? Also be sure you are not measuring from the GFCI plug as you will not read it the same as the others.

Hi there,
Nothing about the bumpy dirt road would have done this but the 10 years of storage might mean that you've got dirty slip rings. Plugging a drill into the 10Kw generator isn't going to tell one much about the power coming out of it, you need a stove :-)
After a camshaft replacement I'd want to use the "Hz" function of the DVM to make sure I was getting 60 Hz.

Regards,
Carl

Usually the cause of slightly low voltage like this is that the engine is not running at full operating RPM. Find the high speed adjusting screw on the govenor linkage and adjust the engine RPM until the output is 220V - 240V

Low voltage


You have overloaded the generator and have blown a capacitor, resistor or similar item that will only allow half the voltage output to the recepticals. I know I have done this too.

I,ve got an Briggs and Statton elite 10000 watt generator, it wont supply enough power to the house evrything is dim lights etc, Ive used it amny times before it will pretty much run the whole house...


Does it appear to be running as fast as it always did, as in RPM's are same as usual? If there is a fuel problem and rpm's decrease due to that, voltage will drop as well. Other causes may be internal problems with generator circuits etc, and will need technician to troubleshoot it properly.
You can try increasing the throttle manually and see if voltage comes up.

Black max 7kw generator high voltage output


Those voltage readings MAY be normal.

The AC waveform may cause your meter to read inaccurately. You would need to use a TRUE RMS meter to accurately read the voltage.

The siple meters actually read the AVERAGE voltage and then are calibrated to mulltiply it by the "form factor" for a sine wave. OFTEN these generators don't produce a clean sine wave. A square-ish wave will read higher on the garden variety meters.

Compare the brightness of a lamp comparing to when run on your utility.

The frequency depends on engine speed ... yours is running a bit fast...check it under at least half load and if off, adjust the govenor slightly.

Output is only 99 to 100 volt. Unit works fine


hmm.... try running it for a while with something plugged in that won't mind the voltage drop... like a light bulb..

There is absolutely no voltage output. What


My generator has a switch to turn on the output, you must turn it "ON" to get power.

Honda generator em 1800


Honda generators are very reliable and are easy to adjust. The best way to check for proper output is to use a meter that can check cycles and voltage. Set meter to htz or freq and adjust the engine governor to 60 cycles. When the engine is turning 3600 rpm it is at max power and the generator may be producing ac voltage ranging from 115 to 125 at 60 cycles. When you draw power from the generator the engine governor will try to overcome the stress and maintain 3600 rpm. The engine must be well maintained to produce full power. Service oil, filter, plug and valve adjustment. Some engines have a spark arrester installed in the muffler that may become blocked with carbon. If engine is producing full power and voltage/amps is low then check brushes, capacitors, and/ or voltage regulator. Most problems occur when too much power is requested from rated generator. Example, trying to connect an 1800 watt air compressor to generator. The compressor may draw double the stated wattage upon starting and cycling. For longest generator life, It is best to use only 75% of rated output. On an 1800 watt generator use max wattage 1350. If you actually need to use 1800 watts then the best generator would be a 2500 watt. enjoy
