Battery Boost circuit is not closing. Could be:

1) 400 amp fuse (in "doghouse")

2) Battery Boost solenoid

3) Oil pressure switch

All pretty common. I had the blown 400 amp fuse (from "low house battery voltage/high current" event) all easy fixes. Take your metal watch off when you crawl into doghouse

Assume you are using the boost switch up front. I don't have the 400 amp fuse on my coach but my boost solenoid did fail. I found out when my house batteries were not being charged with the engine running.

Try starting the engine and check to see if the voltage to both sets of batteries is the same. If so, your boost solenoid is working. If not, time to test the solenoid.
