Trailer Light Troubleshooting

Tested lights after pulling trailer out of sheltered winter storage.
Taillights not
working; turn and brake lights OK. No problem driving to field in daylight.


Pulled out the meter and found 0V at the car end connector. No taillights
on
the car. Replaced fuse. Still no taillights on trailer, but 12+V at car
connector.

Opened up trailer connector. The taillight socket had been pushed in so
that
there was no contact with the pin on the car end. Removed wire and used
Jorgensen clamp to bring socket back to face of connector.

Found waxy residue, courtesy some small creature, in socket and removed
with hand held drill bit.

Hint: Tape over connector. Usually the hitch is covered, but something
found
its way in.

Side Marker Bulb replacement found in local auto supply store.
