7-Way Round Pin Trailer Tester

The Kefly BB888 is a new corded electric ohmmeter designed to replace part 7865L and diagnose seven round pin trailer circuits. It connects directly to the truck connector so you can verify left and right turn signals, hazard lights, brake lights, clearance lamps, tail tags and ABS circuits with LED indication.

Mechanics verifying seven circuit functions

Technicians who need to check all seven trailer circuits on a round pin connector will find the winged handle useful for quick removal after testing. Shops requiring a tester for flat four pin or five pin connectors, or anyone needing voltage readouts instead of simple pass or fail LEDs, should look at other tools.

Replaces part 7865L for seven circuit testing

The single specification that decides fitment is the 7865L cross reference for seven round pin applications. If your trailer or tractor uses that connector standard the tester will plug in and display each circuit status through its LED array.

Questions about this item

Do the LED indicators on the Kefly BB888 ever need replacement?

The LEDs are built into the tester body and are not user-replaceable; if one fails the unit would need to be swapped out.

What stops the Kefly BB888 from testing a circuit continuously?

The tool draws power from the vehicle connector, so testing stops when the ignition is turned off or the plug is disconnected.

Does the Kefly BB888 get hot or make noise during all-day use?

It has no fan or moving parts and only lights low-current LEDs, so it stays cool and silent during extended testing.
