Question about Electrical Supplies
Ive flashed this and still not working, any other other possible fixes to try before replacing entire generator part?
Ohm the rotor between the rings with a good meter, and also from each ring to ground metal shaft of the rotor. You should have a low resistance between the rings, and zero to ground. Also disconnect the stator wires and do the same. I doubt you have to change the whole generator. Make sure you have battery voltage on the brush wires while cranking, if you do then the control AVR is working. If you don't then its a control board issue

Hi, remove the electric control panel & check the wiring as sometimes we have seen the wires coming off the voltage change over switches.
Also some of these units you can check the connections in the rear of the alternator & if it has brushes that they are not stuck.
Another problem we have had is the trip switches have went faulty but still switch operates ok, they need to be checked with a probe type tester for conductivety.

Most generators have several circuits incorporated within the windings. There are usually two 115v windings, one or two windings that produce power and sensing voltage for the regulator that supplies power to the armature (produces magnetic force) and sometimes a 12v winding to supply power to charge the battery. The two 115v windings power one 115v plug each and together power the 220v plug. Each outlet has a breaker and or ground fault. Since the 115v plugs are working indicates that the 220v plug must have an open/broken wire or faulty breaker. Easy to check, however you must open cover to wiring compartment and trace wires. Should be easy fix. You do not have to start engine to find broken wire. Use ohm meter instead. With engine off, Insert probes into 115v plug and obtain ohm reading. Then insert probes into second 115v plug and obtain similar reading. Look for same reading at the 220v plug (remember 2 circuits of 115v, ground and neutral). Good luck with your repair and email if you have other question.
