The large terminals are non-directional and can be wired in either direction.
Power connections should be fused according to your application, no more than 18” from battery.
No fuses are necessary for installations where the power cables are shorter than 18”, for example if the
2 batteries are side-by-side.

Adding a Secondary Battery
Using an isolator when adding a second battery will keep the batteries from discharging
each other and allow you to run accessories from the Secondary Battery without draining
the Primary Battery. When installed as described below, the two batteries are automat-
ically connected when the vehicle is started and running and disconnected when the
vehicle is off.
High Current Relay/Solenoid
SGP Series relays can be used in applications requiring 80A-500A current like motors, winches, com-
mecial equipment, etc. The two small terminals are for switching the relay on and off. Either one of
the small terminals should be connected to chassis ground or other ground location and the other
terminal to switching power output. Switching power must be between 10 and 16 VDC. The relay
coil draws less than 1amp when switched on.
