Automotive Diagnostics and Testing

Simple Solutions for Common Problems

We understand the time and budget pressures involved in automotive diagnostics and testing, and we make tools to help you get the job on time, without wasting time on switching parts in and out. 

Engine Misfires

Misfires are a notoriously difficult problem to detect and diagnose, which is why we created the GTC505.

The GTC505 Engine Ignition Analyzer can tell you exactly which cylinder has an ignition issue, even if the issue is infrequent. This tool is very easy-to-use, and requires no setup. The 505 will help you detect cracked COP modules, bad coils, and faulty ignition wiring.

Electrical Faults

The FF310 Faultfinder is perfect for tracing corroded or damaged wires and locating the fault. 

The transmitter’s leads are hooked up to the faulty wire, and it transmits a signal which the (wireless) receiver can picks. The receiver produces a ‘beep’ when near that wire, so you can follow it until the fault. 

Power Problems

Simple tasks like checking whether you’ve got a blown fuse, or which wires have power can take a long time on today’s complicated cars. 

Our CT8002 Cordless Circuit Tester was designed to help you quickly check for power. This tool is so popular that it has been in production for over 30 years!

Current Leaks

Small current drains can kill batteries, while also being tough to track down.

The CM100 Milliamp Clamp Meter was specifically designed to help you find and fix these electrical gremlins!
