Circuits are identifi ed on the fuse label located on the inside of the electrical cover. Remove three wing nuts,
turn cover over to view.
Battery Boost Solenoid
The battery boost solenoid is located in the battery compartment. A dash-
mounted momentary switch is added to provide a boost for the engine batteries
from the house batteries in case the chassis batteries are weak and will not crank
the engine.
When traveling, the solenoid is engaged, charging both the house and chassis
batteries at the same rate of voltage.
Relays
The motorhome uses various relays to operate electrical equipment such as lights and
motors. If a relay needs to be replaced, carefully record the location of each wire and all
markings or labels.
Relays can look the same in appearance, but differ in function. Note that on the
side of the relay is a schematic drawing identifying if the relay is 87 or 87a relay. These
current ratings differ, and if mixed, will create problems. Ensure the replacement relay is
of the current rating to assure proper operation.
