Lite-Check says its 720 Pro-Check eliminates the need for trailer electrical circuit diagnostics. The device automatically displays the circuit with voltage, amperage and circuit conditions (good, open, short, open ground, chassis ground), according to the company; the fault alarm shuts off whenever the fault is corrected. A full function remote control is optional.
