An essential diagnostic tool for testing potentially faulty electro mechanical relays. This tool tests both 12V / 24V relays, with four / five pins (not late model Ford 4 pin).

Simply plug the relay into the tester - using 12V vehicle power, the relay will be cycled 10 times with the tester applying a signal to the relay coil while checking the function of the internal contacts. The tester applies load to the internal contacts to detect excessive resistance.

• Quickly test 3 common types of electro mechanical relays
• Test relay coil resistance / relay contacts / cyclic testing
• Relay coil resistance: 20 - 500 Ohms
• Test voltage for coil: 9V
• Contact resistance threshold: 200 milliohms

Say goodbye to the guesswork in electrical diagnostics. The ET7386 Short Circuit Diagnostic Kit is a professional-grade solution designed to streamline the process of tracing short circuits in automotive and electrical systems.

Manually Resettable Circuit Breaker Fuses: Includes 7 standard blade and 7 mini blade fuses ranging from 5A to 30A. These fuses trip like conventional ones but can be reset for repeated testing - no need to replace them after each fault.

• 7 standard blade / 7 mini blade resettable fuses
• Fuse ranges: 5A | 7.5A | 10A | 15A | 20A | 25A | 30A
• Includes 2x 300mm extension loops

Professional disconnect pliers ideal for disconnecting straight airline quick connectors on heavy duty air brake systems. Interchangeable head allows the pliers to be used on a wide range of connectors.

• Disconnect airlines with 6mm | 8mm | 10mm | 12mm | 15mm | 16mm diameter

Fuse / relay boxes on late model vehicles are often difficult to access due to tight spacing. These pliers are designed with a special swivel jaw to access tight spaces not accessible to conventional pliers. A specially designed tip fits relay slots / edge of relay covers.
