Testing Trailer Lights & Connections
1. Connect the PP3S to a good battery.
2. Clip the auxiliary ground clip to the trailer ground.
3. Probe the contacts at the jack and then apply voltage to them. This lets you check the function and
orientation of the connector and trailer lights. If the circuit breaker tripped, that contact is likely a
ground. Reset the circuit breaker by letting it cool down (15 sec.) and depressing the reset button until
in clicks into place.
