GROUND ACTIVATED RELAY
A ground activated relay is just the opposite of the 12 volt activated relay, 12
volts (battery constant or switched) is supplied uninterrupted and the ground wire is
switched. An example of this method is a thermostat operated fan relay. In this case
however, a thermostatic switch would replace the switch in the drawing below. Like
mentioned before, the ground activation method is best used when a component is
operated by an unlit switch from the interior of the vehicle.
CIRCUIT BREAKERS & JUNCTION BLCOK
Three 40 amp Circuit Breakers have been provided to connect power to Relays.
Each 40 amp relay will be wired to its own circuit breaker, while the two 20 amp relays
will share a 40 amp circuit breaker.
The Junction Block will be used to distribute battery power to the fuse block and
to the circuit breakers. This will help from having too many wires connected to the Maxi
Fuse or from having to make splices to high amperage feed wires.
