Hi, I have a 2007 Beaver Contessa Bayshore with Cummins 400 engine. For a second time, the Engine Warning light has come on and the tachometer goes to max reading. I pull over, turn the ignition key off, then restart the engine and everything seems ok. The first time this happened was about 2.5 months ago. It happened again yesterday. I am camped by a retired Cummins engineer who has a engine diagnostic device but we don't find the engine diagnostic plug. Can someone tell me exactly where it is on the 2007 Beaver?
THANKS!!
