Red automotive circuit and relay tester with battery leads

YOUR NEXT GARAGE CHECK STARTS HERE

Check the circuit.
Then make your next move.

Get a voltage reading, check polarity and run basic checks on compatible automotive relays with one handheld tool. A practical addition for mechanics and experienced garage DIYers.

12V / 24V vehicle power Digital voltage display Compatible 4 / 5-pin relays

CHECK BEFORE YOU REPLACE

More useful clues. Less guesswork.

01 / VOLTAGE

Read the number.

The digital display adds a voltage reading to your electrical checks, giving you another clue when tracing a circuit.

02 / POLARITY

See the signal.

Red indicates positive; green indicates negative or ground. Use the reading together with the correct circuit conditions.

03 / RELAYS

Check the relay.

Built-in sockets support basic checks on compatible 4- and 5-pin automotive relays. Match the pin layout and rated voltage first.

Experienced garage DIYer with the automotive circuit tester

A place on your workbench.

A light or horn stopped working? Start with the relevant electrical checks. The probe, display and battery-clamp leads keep the essentials together while you follow the vehicle's repair procedure.

Positive and negative indicator information on the real red circuit tester

Polarity at a glance.

Use the red and green indicators alongside the voltage reading to help identify the circuit's power or ground condition.

Close-up of the digital voltage display and probe

A reading you can work with.

The screen shows voltage directly. Readings depend on the vehicle and test point; interpret them using the relevant service information.

Circuit tester beside compatible four- and five-pin automotive relays

Basic relay checks, kept close.

Select the correct 4- or 5-pin mode and follow the instructions for the compatible relay's voltage and pin arrangement.

A relay click alone does not prove contact performance under load. Additional load or voltage-drop checks may still be needed.

Automotive tester and blade fuses shown as garage maintenance context

Start with the right test point.

Check the appropriate powered fuse test points and compare circuit conditions. An unpowered circuit can change how you interpret the result.

ADVANCED FUNCTION / KNOW THE CIRCUIT

Power output for suitable component checks.

The polarity switch can provide power or ground for suitable component testing when used according to the product instructions and vehicle repair information.

Use only on appropriate low-voltage DC vehicle circuits. Do not inject power into airbags, ECU connections, sensitive sensors or communication circuits. This is not a household AC tester.

Included circuit and relay tester, battery leads, clamps and auxiliary probe

KEEP THE ESSENTIALS TOGETHER

Your circuit-checking kit.

Included

Red circuit + relay tester
Attached lead with red and black battery clamps
Auxiliary probe lead

Relays, fuses, vehicles and other workshop items shown in scenes are for demonstration.

Quick fit check

Vehicle power: compatible 12V / 24V DC battery systems.

Listed circuit range: DC 3.5–36V. This is the stated test range, not the required power supply.

Relay support: compatible standard 4 / 5-pin layouts; match the relay rating.

Color: Red.

A SIMPLE CHECKING ROUTINE

Connect. Choose. Check.

1 / Connect correctly

Confirm the supply voltage, secure the battery leads and follow the instructions.

2 / Choose the check

Use the correct circuit procedure or relay mode. Check the relay rating and pin layout.

3 / Read in context

Interpret the display and indicators with the circuit conditions and service information.

Before you add it to your toolkit.

Will it read engine fault codes?

It is a low-voltage electrical circuit tester, not an OBD scanner. It does not scan or clear engine fault codes.

Will every automotive relay fit?

No. Check the relay's 4- or 5-pin layout and rated voltage before use. Different relay types or pin arrangements may need another testing method.

Who is this tool for?

Mechanics and experienced DIYers familiar with vehicle electrical systems. Learn the product instructions before using the output function.

12V and 24V low-voltage vehicle use context for the circuit tester
