Draper Glow Plug Tester 12-24V

The Draper Glow Plug Tester 12-24V is a handheld device that allows you to test glow plugs in situ. This can be helpful in diagnosing problems with your vehicle's engine, as glow plugs are responsible for pre-heating the engine before starting.

The tester has a simple design, with a large LCD display that shows the resistance of the glow plug. It also has a built-in torch light, which can be useful for illuminating the engine bay when you're working on your vehicle.

To use the tester, simply connect the black alligator clip to the vehicle's earth and touch the positive end of the glow plug with the tip of the red test probe. The tester will then take a reading and display the results on the LCD.
