Question about Northstar Generator 13 Hp, 8000 Watt, Trifuel
I have a 8000 watt generator with high voltage low cyles
I worked at a tool rental center while going to college and learned how to service generators. Most appliances/tools require 50 to 60 cycles at 110 to 120 v. Your engine was designed to give maximum horsepower at 3600 rpm. Adjust the engine speed to produce 60 cycles and the engine should be at 3600 rpm and producing around 120v max. (Some special generators were designed to produce 230v 180 cycles, check manual) If your generator incorporates capacitors check them for at least 95% of printed uf value. They should be removed from circuit for testing. If there are two caps and one is weak make sure the new cap reads close to value of remaining cap. Finally there is usually a voltage regulator that varies the power to the armature magnet trying to maintain steady voltage depending on amp draw and engine condition. This regulator has no adjustment and is pass or fail type of item. Good luck, enjoy
