The reasons for the generator dose not generate electricity are as follows:
1, the magnetic pole of the generator loses magnetism;
2, the excitation circuit component is damaged or the circuit is broken, short circuit or grounding phenomenon;
3, the exciter brush has bad contact with commutator or the brush frame pressure is insufficient;
4, wrong connection of excitation winding, opposite polarity;
5, poor contact between generator brush and sliding ring, or insufficient brush pressure;
6, broken circuit of generator stator winding or rotor winding;
7, loosening of generator lead wire or poor contact between switch and wire; Fuses, etc.

Pull off the cover at the end of the generator and locate a 2 lead capacitor, it should read 130UF 200V and replace it, they often go bad and you will not have any output if they are. colman has them for 20.00 shipped. 1-800-445-1805

Try replacing the capacitor. You can buy it from When you pull off the power end of the generator look at the diodes also. If they look toasted replace them as well

Hi, The 4000 rv unit unit is equipped with full diagnostics, and is indicated by the status light blinking. The blinking sequence, blinks a code as to the fault. If your unit runs and the status light is on without blinking, it is either the circuit breaker on the genset or in your distribution panel that needs to be reset. Good Luck, this should Fixya!

SOURCE: My coleman 1500 generator runs fine but does not

Should be a circuit breaker on the side where the outlets are. Could also have a reset button that pops out. Good luck

Generac guardian rv generator starts and runs but after a couple minutes the power stops.....generator still runs??

Usually the generator will shut down if the ac is not present coming out of the generator. You stated that it still runs but no power on the output. Check your breakers first to make sure they are working properly. Depending on what board you have you can check to see if ac is present getting back to the board as well. If your board does not have this then they are using the frequency as a safety disconnect feature. That would lead you back to the regulator or loose connection or..dirty slip rings if this unit has brushes.

Engine runs fine but probably overloaded the generator. Is it just brushes or coil too.

Site unseen i would say its neighter the brushes or the coil . And more the likely the problem is with a transformer converting the DC off the generater to AC for your output . If the engine runs ok and the armature in the generater spins ok and you don;t have a million hours on it should work at least somewhat . Try testing the output on the AC side see what you get for AMPS you will need a muilty meter set to AC amps

Coleman Powermate Powerbase 4000 -no AC Need Field test procedur

Check the voltage sent to the field when running. It will probably be around 12 volts. You can try connecting a lantern battery BRIEFLY to the field to re-magnetize the field. Try bothe polarites.

Some have had a bad rectifier and one had a bad transformer that generaates the low voltage from the generated output. He had a broken wire from the winding to the wire from the transformer. He was able to reconnect the failed solder joint.

Coleman 5000 generater-no AC output

have you conected the brushes on the right way? the leads are + and -.

you can run it up and use a 12v battery and connect it to the brushes correct polarity, with the othe LEADS removed and taped can shock you and chect the out put it it around 100 120v chech the AVR or brush polarity.

If yours dont have brushes it will have a capasitor that is prob out of spec.
