Engine Died

We were traveling eastbound on hwy. 15 in our 2005, 34 ft. Alpine with the 400 h.p. ISL engine when one half way between Barstow and Las Vegas The motor died - I lost all electrical power to the engine. All electrical connections appear to be tight and I can not find any blown fuse. The lost electrical power appears to be only engine related. Any and all help will be greatly appreciated. --Tom

Have your ERS tow you to the nearest Cummins shop.

Are you sure you lost electrical power to just the engine? Are your chassis bats showing a full/good charge? A shot in the dark but try turning off, wait a few seconds, then turn on both your house and chassis bat main switches to re-cycle your Vansco. A shot is the dark but worth a try.....

Check the white ground wire from the engine's ECM to the ground lug on the engine. It is a thinish (about 14ga) wire the wrv just strung across the gap between the right frame rail/ battery compartment to the engine block and has been known to get snagged or pulled loose from the ring connector (even though it may appear connected in the shrink wrap the connector. Good Luck

Could be corroded battery cables &/or connections
What was the voltage shown on the speedo window prior to the failure?

My guess is like everyone's else, lose ground wire to the engine. There are several grounds on the engine, look on both sides from the bottom. Tighten all of them, coat with good dielectric grease sold in HD, Lowes, Ace, etc, so the corrosion does not come back. Back of Alternator might have lose connection as well.
