Briggs and Stratton standby generator issue
Hello! I am new to the forum and looking for a little help.
In my travels, I acquired a used propane/NG powered B&S 7kW Model 40301 Generator.
Its set up for propane right now. Fires up and runs like a champ. Good voltage and frequency unloaded and not plugged into anything.
W/ the breaker off but the unit running, I plug the generator into the generator house receptacle (house is set up w/ male 4-prong plug to my fuse panel w/ inter-lock switch installed). As soon as i plug it in (not sending power to the house), the generator trips due to "low frequency)"
Even with the gird power off to the house and the gen plugged into the house but not sending voltage, it still faults due to low freq.
When I got it, it wouldn't stay running. I traced it back to the control board and replaced that.
Any ideas? voltage regulator?
I love troubleshooting and fixing stuff but this has me and my buddies stumped. I am use to big generators (I work on wind turbines).
Thanks for the help!!
