A digital LCD circuit tester for checking 3-48V DC electrical systems on vehicles and other low-voltage applications. Built with a computer safe design, it gives a clear voltage reading on the backlit display and uses a stainless steel probe for direct contact when tracing live and earth connections.

Used for fault finding, servicing and electrical checks on cars, vans and bikes, this tester helps when tracking down power supply issues, checking fuses, testing wires and confirming positive or negative charge. The long probe is especially useful when working behind trim, around engine bays or in other confined areas where access is awkward. For garage work, workshop use or home vehicle maintenance, it gives a straightforward way to check whether a circuit is live and what voltage is present.

The 3-48V DC range covers a wide spread of common vehicle electrical testing jobs, while the backlit LCD screen is easier to read in low light or under dashboards. An 11ft uncoiled cable gives good reach around the vehicle without needing to keep repositioning yourself. The sharp stainless steel probe is intended for easy wire piercing, which can help when checking circuits quickly during diagnostics. Current draw is listed as 17mA on 3-20V systems and 10mA on 20-48V systems. A practical choice for regular electrical checks where clear readings and good access matter.

• Voltage range: Suitable for DC systems from 3V to 48V.
• Display: Backlit LCD screen for clear voltage readings during testing.
• Probe: Sharp stainless steel probe for easy wire piercing and contact.
• Reach: 11ft uncoiled cable helps when working around larger vehicles or awkward areas.
• Function: Checks both positive and negative electrical charge.

Useful to keep close to hand for vehicle electrical diagnostics and routine fault finding.
