Isolator Relay
The Isolator Relay provides a simple means of isolating the two battery sys-
tems, house and chassis, and connecting the batteries together when the engine is
running.
A momentary dash-mounted switch is added to provide a "BOOST" for the engine
batteries from the domestic batteries.
When using the battery boost switch, the relay may have to deliver the full starting
current to the engine batteries. The relay contacts must close and provide low resist-
ance without the harmful effects of arcing. To be sure relays can perform under harsh
conditions, the contacts are protected with a unique antioxidant coating. The relay
is of heavy construction and can easily deliver the needed current. In a battery
charging situation, both batteries will charge at equal 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 prob-
lems. Ensure the replacement relay is of the current rating to assure proper
operation.
