The issue now is the rpm's are way too high (90+Htz) but constant. The output voltage was 240, so the ARV is working. Unit will run for 10 to 15 seconds before shutting down with a fault of [RPM sense loss]. I'm suspecting a bad controller, but feel I should be checking where the controller gets it's rpm sensing.To change the oil on a Generac generator, use a socket wrench to disconnect the drain plug and drain the old oil.

Generac 15kw Model #0047602. Unit was intermittently shutting down on a flashing overspeed fault. Found very high resistance between the brushes & slip rings. Cleaned the slip rings, and replaced the brushes. Also replaced the voltage regulator at the same time, and adjusted the new regulator per Generac instructions.The power is fine from the generator until we put 4 or 5 pumps on line. When this happens the voltage from the generator starts fluctuating enough to start causing problems, lights flickering, drives faulting on input loss and overvoltage, etc. This is a good sign of harmonics affecting the regulator on the generator.The RPM loss code can easily be cleared by hitting the off button and then enter. Does the unit crank at all before showing RPM loss? The coils must be installed per the directions with BOTH spark plug wires facing towards the rear of the generator (front coil wire gets bent in a 180° turn to come out the front).The wires would have to get very hot to heat the connected fuse enough to lower the fuse trip point significantly. A bad connection to both fuse blocks might cause them both to overheat. But a more likely cause for both fuses blowing would a fault from the sensing circuit to ground or neutral in the control board.Of course once it changes to RPM Sensor Loss it sits there like a rock and does nothing until I check it and reset it. I cleaned the battery terminals and the battery is only a year old and passes a load test. My novice Spidey Sense leads me to believe that 1) the contactor is flaky or 2) the control board is flaky.
