RPM Sensor Loss 1501
ALARM
This RPM alarm is set when a 2 cylinder unit was already running and stalled or lost the RPM signal from the ignition coils. Possible causes could be a fuel issue, the LP tank is empty, 1 or both ignition coils are damaged, or the unit was overloaded quick enough that the engine stalled and set the alarm.

Possibly a fuel flow issue.

Try running without load for awhile, if it faults with no load then either an ignition module or control board or fuel. If it only faults with significant load, then more likely a fuel flow or engine is stalling from sudden increase in load.

Why is my generator shutting down with fault code 'over rev'?

Contact them direct. This is an undocumented error. The obvious thing to do would be to reduce the engine speed?

WHAT DOES SENSE LOSS MEAN

RPM Sense loss means that the generator controller hasn't received a valid signal from the ignition coils for 3 seconds of attempting to start. Probably a dead or low battery or bad ignition coil. Replace the battery and try again. Call dealer if problem persist.
