1. Connect the PP3 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 func-
tion and orientation of the connector and trailer lights. If the circuit breaker tripped, that con-
tact is likely a ground. Reset the circuit breaker by letting it cool down (15 sec.) and depress-
ing the reset button until in clicks into place.
