Hello, my name is ***** ***** I am going to assist you with this.

First, make sure the circuit breakers on the genset are turned on. The way this unit is wired, it will not stay running with the breaker off.

If the breaker is on, you need to open up the control panel to access the control board.

On the control board, locate the 2 single wires labeled E1 and E2.

Connect a voltmeter across them, and start the genset.

How much voltage does it show?

It still isnt staying running, it runs , 10/15seconds shuts down , then does it again , etc. something seems to be telling it to shut down , that the power is on?��

Hank it has run good for ten years , then all if a sudden , won't stay running after it cranking up????

How much voltage is it showing across the E1 and E2 wires for the 10 seconds it will run, with the breakers on?
