Trailer Lighting, Control and Signaling Circuits Tester
First Claim
1. A circuit tester for engaging a connector of a vehicle, the connector electrically connected to a plurality of trailer device driver circuits of the vehicle, each trailer device driver circuit for powering at least one electronic trailer device through a trailer connector of a trailer, the circuit tester comprising:
- an enclosure adapted to contain a testing circuit, the testing circuit including a plurality of input lines, a logic means, and an alerting means, the logic means capable of causing the alerting means to produce a plurality of distinct alerts;
an input connector adapted to mechanically and electrically engage the connector of the vehicle and electrically connected to each input line of the testing circuit;
whereby with the input connector fixed to the connector of the vehicle and each of the trailer device driver circuits activated in turn, the testing circuit causes the alerting means to produce each of the distinct alerts in turn.

Abstract
An electronic circuit tester is disclosed which is utilized for the testing and troubleshooting of the various lighting, control and signaling circuits required in the towing of a trailer, vehicle or other conveyance. The tester generally comprises an enclosure, which may be included as a part of a wiring harness connector, or separately attached to a wiring harness connector by means of electrical wiring. The testing circuit includes a plurality of input lines, logic means, and an alerting means. The testing circuits cause a distinct alert to be produced in response to each distinct test of the trailer device driving circuits of the vehicle.

10. A combination circuit tester and connector for a vehicle, the vehicle having a plurality of trailer device driver circuits each for powering at least one trailer driver through a trailer connector of a trailer, comprising:
-
an enclosure having a vehicle connector electrically connected to each trailer device driver circuit of the vehicle and adapted to mechanically and electrically engage the trailer connector of the trailer, the enclosure further adapted to contain a testing circuit, the testing circuit including a plurality of input lines, a logic means, a test mode switch, and an alerting means, the logic means capable of causing the alerting means to produce a plurality of distinct alerts, each input line electrically connected to one of the trailer device driver circuits of the vehicle, the test mode switch disabling the testing circuit in a “
pass-through”
position and enabling the testing circuit in a “
test”
position;whereby with the test mode switch in the “
test”
position and each of the trailer device driver circuits activated in turn, the testing circuit causes the alerting means to produce each of the distinct alerts in turn. - View Dependent Claims (11, 12, 13, 14, 15, 16)
