Electronics and Diagnostics

Looking for a spark plug tester? Lisle covers four here: the 20610 inline tester connects between spark plug and plug wire and flashes a mirror image of the spark with the engine running; the 20580 adds a 7-inch extension plug wire for coil-on plugs that are recessed and hard to reach; the 20700 is made for coil-on-plug systems with no plug wires to run an inductive test; and the 50850 checks ignition spark without removing the spark plug.

Alongside them: six Lisle circuit testers (29500 high-low, 27430 24V, 32900 tester/jumper, 28620 with buzzer, plus the digital 29050 3-30V and 28830 3-48V), eight color-coded relay test jumpers for the 60610 set, four stethoscopes, a magnetic soldering clamp, the Autel BT506 battery and electrical system analyzer, the AME TPM144 TPMS tool and Mastercool charging station, scale and solenoid module.
