A portable light-weight hand-carried device for testing the electrical system on any trailer or RV equipped with a standard 4-flat or round 7-blade RV connector without hitching up to a tow vehicle. Accepts adapters for 5-flat and round 6-pin connections.
Less than half the size of a car battery, completely hard-wired and packaged in a durable marine grade housing.
No delicate printed circuit boards or internal power draining components. Assembled in the USA.
Avoid the risk of blowing tow vehicle fuses caused by trailer malfunction due to corrosion, faulty components, animals attracted to and chewing on soy based wiring insulation or when plugging an untested trailer into a constantly energized tow vehicle connector.
Check LED and incandescent running lights, brake-turn signal lights, electric brake operation, 12V power circuit and auxiliary power circuit.
Each circuit is color coded, independently controlled and circuit breaker protected with provision for multi-meter testing including amp draw on electric brake magnets without splicing or probing into trailer wiring.
Connects with jumper cables to any 12 volt automotive, marine, recreational vehicle, motorcycle or lawn tractor battery.
Easily converts to a self powered stand-alone system by installing an economical lawn and garden battery, no tools required.
Test anywhere regardless of trailer location. Convenient for consumers and businesses alike. Enables customers to drop trailers off at repair shops or inspection stations.
