Glow plug check

This Glow Plug Analyser from Sealey aids quick diagnosis of glow plug failure or degradation without disassembling the plug from the engine.

It connects directly to the vehicle’s battery and can be used on any 12V DC vehicle system. The six LED readout indicates glow plug status and also if the battery contains enough charge to power the plugs. It is currently on offer in the Sealey Summer Promotion which runs until September 30.
