The Perfect Trailer Tester For Trailer Electrical Systems, Lighting, and ABS
Electrical issues and the circuit affected are identified for easy diagnosis and repair. In addition, The Evaluator 740 safely tests circuits for these shorts with micro-bursts of voltage instead of a constant feed, alleviating the “smoke test” produced with other methods. Electrical issues are identified as circuit to circuit shorts, open circuits, open grounds, and chassis shorts.
In addition to fully testing electrical circuits, all major ABS manufacturer fault codes are displayed on an easy to read, 4-line LCD screen. Also, ALL faults (stored and active) are available for technicians to use for diagnosis and repair. Simplify your ABS diagnostics with one tester rather than dealing with blink code or multiple devices.
The Evaluator has 2 versions.
Includes a 7-way “round-pin” connector and remote control. 110 VOLTS
Includes a 7-way “round-pin” connector and remote control. 12 VOLTS
The tester is designed for negative ground vehicles
(black-negative, red-positive). In case of reversed battery leads on the power cable, the tester will not operate.
Power Supply Set Up:
Attach the battery cable clamps (or ring terminals) to a 12Vdc automotive battery, or a regulated power supply (such as the LITE-CHECK 311R). Turn the power switch located on the back panel of the tester on for operation.
Low Battery Messages:
NOTE: The tester will not work properly if the battery is not charged to a full 12+volts. The tester will not operate and will possibly lock up if the power is below 10.5 volts.
