Hello, thank you for requesting me, and for the confidence in my abilities!

The single most common cause of this issue is that the set is nolonger producing electricity.

The first thing you need to do, though, is to check your oillevel and make sure it is full.

Low oil pressure will also shut the set down.

If the oil is good, remove the control panel from the front of the genset.

Set your meter to ACV.

Connect the black lead to a good ground.

Connect the red lead to the back of the circuit breaker (either one), on the terminal farthest away from you.

Press and hold the start button for 6 - 8 seconds, and note the voltage.

How much voltage is there?

I now I can't even get it to start
Expert:  Hank F. replied 1 year ago.

Have you checked to make sure you have at least 1/4 tank of fuel in the coach?

Have you checked to see if you are getting spark to the plugs?

Customer: replied 1 year ago.
After several rotations there was a very weak spark on the front plug did check the back one yet it system to rain
Expert:  Hank F. replied 1 year ago.

The spark on these units is not all that strong. As long as it is blue and not yellow, it is sufficient.

Customer: replied 1 year ago.
I will continue to check I used a spark tester ands think I will pull the plug and charcoal there. I will check both plugs and let you know
Expert:  Hank F. replied 1 year ago.

Sounds like a plan....

Expert:  Hank F. replied 1 year ago.

Have you checked the plugs yet?

Customer: replied 1 year ago.
No spark at the plugs.
Expert:  Hank F. replied 1 year ago.

Ok.

Here is what you need to do.

Disconnect the red and black ignition module wires from theterminals of the coil.

Run a 12V jumper to the red wire of the ignition module. Setyour meter to VDC and connect the black meter lead to a good ground.

Connect the red meter lead to the black wire coming from theignition module.

Using a 3/8" Allen wrench in the rotor through boltlocated in the center of the right hand side of the set, slowly turn the enginecounter clockwise as viewed from the right end. The meter should read 12V for1/2 revolution and drop to about 1V for the other half revolution. Turn themotor through at least 3 full revolutions.

What happens?
