Need a little info guys.
My neighbor just got a older class A with a Onan 5000. He says it starts and instantly dies. He has by passed fuel pump, replaced filter and plugs. He ran out of ideas so I took a look and as soon as you take your finger off start button it kills ignition. I bypassed low oil switch and it made no change. I need suggestions.

A few years back we had two of those onans' in 2 seperate RV's do that , on both it was the voltage regulator.....seems the mice had built a nest all around and on top of it and when started the heat backup just killed them...Chuck
