disconnect solenoid. Should this occur the main ground cable for the house batteries must
be removed for 1 minute to re-enable the solenoid operation.
Always leave the ignition key in the “off” position unless the engine is running

The Load Center contains 12VDC fuses and 120VAC circuit breakers for almost all of the
electrical appliances and circuits in the RV. The 120V Main Breaker (if so equipped) is
located in this panel and will turn off all 120-volt power to the recreation vehicle. The
load center is a hinged panel typically attached to a cabinet face in the main living area.
Locations will vary by model. Refer to the diagram inside the Load Center for specific fuse
assignments. Most load centers contain the same components, but they may be positioned
differently. Not all load centers will include a main breaker.

When house batteries are installed in parallel circuitry with the chassis battery, the charge
level in both connected batteries will naturally equalize. An isolator solenoid is incorporated
to break the connection between the house batteries and the chassis battery when the ignition
key is in the “off” position.
Breaking this connection prevents discharge of the chassis battery (used to start the engine)
when using 12-volt devices in the house section of your motor home. When the engine is
running the isolator solenoid engages allowing the house batteries to be charged by the
vehicle alternator.
