Not having clean slip rings and running your generator attempting to feed power to 120V can FRY/Destroy the Voltage Regulator. The Field Circuit shouldn't test hirer than 25 ohms and at this range the generator will produce 120V without issue or load on the engine, however if your field measures say 50 ohms, well then your generator had to work TWICE as hard just to produce the same 120voltage and this is what burns out the voltage regulator in generators (in general). So, if you haven't used the generator for a while or it's a new machine to you....ALWAYS measure your Field Circuit ohms 1ST!!!....Before you try to produce any 120 voltage with your generator. OR ELSE!!! Keep those breakers shut off and disconnect the Voltage Regulator 12-pin plug as you're going through your diagnostic tests and general maintenance on the engine. Flight Systems offers excellent trouble shooting worksheets and also offer complimentary tech support to help us DIY'ers out. Peace Brother....Great Video!
