Circuit Testers

An extension cable for the ET0700. Ideal for working on trucks/rear of vehicle.

Advanced multi function tester supplied with inter changeable connectors. Voltage supply 8-30V.

A handheld diagnostic tool designed to test circuits / electrical connections.Operates from 3-48V. Includes probe adaptor for testing terminal connections.

This circuit tester is suitable for use with standard 12V DC systems, as well as newer 42V systems. Safe for low current circuits as it only draws 3 milliamps @ 12V. Crystal clear handle providers excellent all round visibility, even in bright light.

• Automotic voltage identification: 12V (blue LED) | 42V (red LED)
• Two super bright LEDs for excellent visibility in all light conditions.
• Safe for low current circuits

Check circuits on all 6V & 12V systems. 70mm insulated probe, with 3.6m retractable cord.

• 70mm insulated probe
• 3.6m retractable cord

This circuit tester is designed for sensitive circuits such as injector pulse, and automotive computer circuits.

Operates from 3-15V (for 6 - 12V systems). Handle glows red for positive polarity, and green for negative polarity. Supplied with 48" ground wire.

• 3 - 15V voltage range
• 75mm probe length

A professional quality circuit tester, with an LED display which provides real time voltage (in addition to indicating power (RED) and ground (GREEN)).

This unit has a fixed 90mm probe. See also ET3426A which is a similar tester, but with a standard 4mm connector.

• Spring cable extends to 3 metres
• 6V - 48V DC testing range
• Small testing current (<10mA)
• NOT for use with 240V AC | NOT for use with airbags

Packaged in a BMC, this circuit tester has a standard 4mm connector which can be used with standard multimeter probes.

Wire piercer / probes / alligator clip included.

• Not for use with airbags / vehicle computers.
• For use with DC voltage only.

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

• Quickly test 4 types of electro mechanical relays
• Test relay coil resistance / relay contacts / cyclic testing
• Relay coil resistance 20 - 500 Ohms

Replacement straight probe for the ET3426 / ET3426A kits.

Safely test voltage up to 1000V AC / DC. Able to verify the absence of voltage even with discharged batteries.

• Conforms with EN 61243-3. CAT III 1000V / CAT IV 600V
• LED indication range: 12V - 1000V AC / DC
• LCD indication range: 6V - 1000V AC / DC
• Rugged double insulated wire
• Continuity / Diode test
• 2x AAA batteries included
