Circuit Testers

Automotive circuit testers and test lights from Lisle. Choose by voltage: the 26250 and 28400 H/D work to 12 volts, the 32900 tests to 28 volts and doubles as a jumper wire, the 28620 tests to 28 volts with light and buzzer, and the 27430 is 24V heavy-duty. The 24550 Computer Safe draws under 21mA at 12V DC and will not damage sensitive electronic components; the 29500 High-Low reads to 28 volts and checks spark plug wires without piercing.
