Hi, I have a 2700kva generator (old applied power model) run by a honda motor. It would be at least 10 years old if not more but was serviced 2 years ago, and hasn't been run since. It runs ok with new fuel. It was recently serviced but I am finding the voltage output low. There is a screw on the carby that adjusts rpm and voltage but when I monitor the voltage going into a ups (with input v display) it is all over the place, up and down by 10v. 1. Is there a cheap plug in pass through style 3 pin voltage meter I can use to give me a readout of the voltage from the generator? 2. Does anyone know if these generators are ok for domestic loads, or is it typical of their voltage to fluctuate a lot with load, and therefore not really useable with TV's, pc's etc? Thanks.
