Question about Coleman Powermate Premium Plus 6250W Portable Generator

Open Question

I have a Makita G1700I generator and it won't run at a steady speed when I put it on Auto power save and connect a small camper or trailer. It keeps oscillating up and down and the voltage varies from 108 volts to 133 volts. I have to leave it on high speed and use more gas. Thank you if you can help me. Marcel

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: Does not generate electric power at 110V or 220V.

To flash fields the genset has to have rings and brushes. The ring towards the bearing or towards you is positive and the back ring is negative. The rings and brushes are on the rotor, which is the part that spins on the generator end. Place a volt meter on the outlet, start the genset, with a 12V battery apply the positive to the front ring and the negative to the back ring. The voltage should climb up to about 50 - 100Volts or more. If this happens then you will need a Voltage regulator. If voltage does not climb up, then check the rings and brushes. Make sure the brushes have a good length and that they touch the rings and make sure the rings have a shiny copper color to them, if they're black clean them with emory cloth until there is a nice copper color and try flashing the gen again. If nothing happens then you need a new generator end or new generator, which ever you prefer. Make sure to use rubber gloves when flashing and look out for rotating parts.

Check the voltage regulator and any fuses or breakers.

SOURCE: no output from my generator

Check the capacitor in the generator head. Will onpen or short cause loss of excitation voltage. Just checked my GENERAC ( no output) and sure enough the cap is shorted.

It wont work. Electricity does not work like that. you can't double the power just by doubling the watts or amps. there is a lot and lots of other things involved.
I would rewire you camper so that half is run be one generator and the other half by the other generator... SO lights and fridge on one and plugs and heater on the other maybe...

I have an early 90's Starcraft pop up camper. I just went to hook it up to the van and the travel lights (running, brakes, directionals) don't work at all. All lights worked when the camper was stored last...


When you say that you have power up to the camper, do you mean power through the pigtail/wiring harness with the tow vehicle connected?

The trailer harness wiring is the only way to power these exterior camper lights, i.e., through your vehicle. There are no fuses within the trailer for the exterior lights. These lights are only fused from the tow vehicle's fuse box. So either the connections in the trailer harness are open, or they're open at the tow vehicle connection.

Do the turn signals work on the tow vehicle? If yes, then the only other thing to check is the turn signal flasher in your tow vehicle. A heavy duty flasher is recommended.

From the trailer, yellow, white, brown, red, green, is connected to your vehicle backup, ground (frame), right turn signal, left turn signal, running lights, respectively.

The trailer's blue wire is for an electric brake connection to your vehicle.

The trailer's small black wire should connect to the vehicle's hot, 12V lead for the interior lights. The large black wire at the trailer hitch is for charging an RV battery on your trailer, if it's supplied with one. Of all of these wires, only the large, 12 gauge, black wire goes to the 25 amp converter, which is fused, for the inside lights of the camper.

I hope this helps.

No running lights on camper trailer


Hey Paul, it's most likely a wiring problem. There is one wire designated for just the running lights. What type of plug does the truck have? Probably 6 or 7 way (6 or 7 wire). You can check the plug-in at the truck with a multi-meter to see if there's power at that point. If there is, then the problem is somewhere from the trailer plug to the lights on the trailer. If you have a 7 way plug, the center plug is for aux. power (back up lights on what you pull, if equipped). One wire is power to the camper battery for a breakaway switch, one for left turn and stop, one for right turn and stop, a ground wire, one for running lights, and one for trailer brakes. To determine what wire does what, 1st with meter check volts of all wires w/ truck and trailer hooked up, truck running, power wire to battery for breakaway should show voltage if equipped w/ a trickle charge, brake wire will show low voltage, approx. 2 volts, apply brakes and should go up to approx. 12 volts, put on L turn signal, meter should go up and down, as power to blinker pulses on and off, do the same to determine which is the R turn signal (put foot on truck brakes will show voltage to brake lights AND brakes, continue w/ process of elimination to determine which is running lights, and exactly where power is not going.

The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.
