Coleman Sport 1850 Generator - Page 3 Questions & Answers
I have 4000 watts coleman
Your generator is rated at 2000 watts at from each 120V line. At 240V it will supply the full 4000 watts. That said, use a volt meter to check the output from each outlet. If it is less than 1900 watts per leg you mmay need an engine tuneup [new plugs, new air filter] OR you may have a partially gummed up carburator. I recommend that you begin by getting a bottle of a fuel additive called Seafoam. Follow the directions to add the correct amount. Run a tank of treated gas through the generator and the engine will run up to it's potential. IF at that point you still don't have the wattage you should you will have to check the breaker and the wiring connections. Regards, Joe
How do i excite a coleman sport 1850 generator?
This unit is capacitor excited, simply pull the terminals from the capacitor and apply 12vdc to the the wires for about 1 second. Then plug capacitor back in reassemble and run generator and check voltages. If the rotor magnetism has been restored and everything else is good you should be producing power now.
There is an alternative way to excite back end but it is a little more dangerous. It involves starting the unit and then applying 12 vdc to either of the 120v outlets for less than a second. This is the best way but it is more dangerous because once the back end is excited the outlet will now be putting out 120 vac. So if you leave your 12 vdc source connected too long you will back feed that source with 120vac. What we've learned to do is to have 2 wires coming out of the outlets with the tips exposed then we take our wires with the 12 vdc source and just brush them quickly against the 2 wires coming out of the outlet.
Engine speed varies
If the unit was stored for a long period of time (6-12 mo.) with gas in it, you may have a gummed up carburator. This is the most common problem with generators (lack of use)
The carb. would have to be removed & cleaned, specificly, the high & low speed jets
Engine runs but no AC or DC output.
- Remove the rectangular snap-fit cover from end bell
- Start generator making sure it's at rated RPM
- Using volt meter test brush terminals.
- Use red+ lead on top or right brush black is - negative
- should see approx. 75 volts DC
If no voltage, need to flash with 12 volts DC same polarity as above, for 5 seconds If you need further help, I’m available over the phone at

Acts like it is not getting fuel
Check the fuel line to see if it is clear. Run a wire through it or blow it out with air. Then if it is ok check the fuel tank to make sure nothing is clogging the fuel there. (Sometimes over the years debris gets into the tank and can clog there.) Had an old mower that did the same thing you are talking about, start and then quit. Had to clean the fuel tank out and then it ran like a champ. Good Luck
Generator will not start
You say there is compression .What was the p.s.i. on the gauge. If below 100 p.s.i.. May have bad ring, valve out of adjustment or bad head gasket. Is there spark and what does spark plug look good, is gap ok . Is the fuel tuned on and kill switch on. Will need more info to help out more.
Coleman 1850 no/low generator output
Both the Hz and the voltage will be wrong if the engine speed is low. You need to use either a DMM with a HZ function to set the engine speed so that you get 61.5 Hz at no load, or use a tachometer to set the no load speed to 3750 rpm.

Features Question
Get a generator that is rated for the amount of power that you can determine you will need.Look at the labels on lighting, appliances, and equipment you plan to connect to the generator to determine the amount of power that will be needed to operate the equipment. Choose a generator that produces more power than will be drawn by the combination of lighting, appliances and equipment you plan to connect to the generator including the initial surge when it is turned on.
How to remove a rusty fuel tank for cleaning
When dealing with specific equipment like the Coleman Powermate Pro 6750 generator, it's important to follow proper procedures and consult the manual for disassembly instructions. However, I can provide some general guidance:
- Look for hidden screws or fasteners: Check for any additional screws or fasteners that may be securing the plastic control panel to the generator frame or the fuel tank. These may not be immediately visible or obvious.
- Disconnect electrical connections: Before attempting to remove the control panel, make sure to disconnect any electrical connections that may be attached to it. These could include wires or connectors for the generator's controls, switches, or displays.
- Release clips or tabs: Some control panels may have clips or tabs that hold them in place. Look for any release mechanisms that may need to be pressed or disengaged to remove the panel.
- Seek guidance from the manufacturer: If you don't have the manual or are unsure about the disassembly process, it's recommended to contact Coleman Powermate customer support or visit their website. They can provide you with the specific instructions or guide you through the steps needed to remove the control panel and access the fuel tank.
Remember to exercise caution and prioritize your safety when working with equipment like generators. If you are uncomfortable or uncertain about the process, it's best to seek professional assistance or consult a qualified technician to avoid any potential damage or harm.
