WIRING FOR A LIFTGATE
Consult the liftgate manufacturer’s installation instructions for details concerning wir-
ing for their product and specific model.
A liftgate will usually require current much greater than 10 amperes . Typically, 100 to 150 amperes is required and some
models require more than 150 amperes . For a liftgate installation a third battery is required for adequate power .
A liftgate installation must have a dedicated circuit to distribute power to the liftgate.
Liftgate Power Source
Liftgate motors will typically use DC power. A convenient power source is the battery. Use Figure 8-27 as a guide. Install
the circuit breaker inside the battery box on the rear panel .
DO NOT use a circuit breaker of lower capacity than the liftgate amperage requirements.
If you do, it could result in an electrical overload or fire. Follow the liftgate installation
instructions and use a circuit breaker with capacity recommended by the liftgate
manufacturer.
