where would you suggest I test circuit board.
Expert:  Wayne replied 6 months ago.

Hi

you need to see if you have any fault codes

Go to the genset and use the switch on the set itself.
Press 'Stop' 3 times within 5 seconds. The light in the switch will start flashing.
If the light flashes 3 times, pauses for 3 seconds, and flashes 3 more times, press and immediately release 'Stop' one more time.

This will put the controller into Fault Read Mode.

The light will flash (X) number of times, pause for 1 second, and flash for (X) number of times again. Count the flashes before and after the pause.

This will be the Fault Code

Customer: replied 6 months ago.
Fault code 47
Expert:  Wayne replied 6 months ago.

Thank you for that

let me look it up

Expert:  Wayne replied 6 months ago.

Hi

Well I have not so good news for you

Fault Code 47 is Ignition Fault.

This may turn out to be a major chore. One of the possibilities is a bad magneto. The magnetos are located under the generator and the genset must be completely disassembled to access them.

This is going to take a service shop to repair

I hope this helped you

Expert:  Wayne replied 6 months ago.

You told me it will not start

Customer: replied 6 months ago.
It will run if I cross starter.The start button will not start it
Expert:  Wayne replied 6 months ago.

Thank you for that

when you said cranks jumping starter

I did not know it started

so your issue is the controller(circuit board )

it is not letting the voltage thru the circuit

That needs to be replaced
