You can attach the alligator clamp either to negative or positive ground, while using the long probe to touch another side. Signal lights will indicate the polarity: red light indicates positive polarity and green light indicates negative polarity.
Also to inspect circuit tester integrity of headlights, taillights, turn signal circuits, faulty sockets, fuse connections and more. Constructed with premium ABS body with higher transparency, shatter-proof and durable.
This auto circuit tester with wide application is not only for cars but also for motorcycles, heavy-duty trucks, trailers, boats, etc, the must-have electrical tester for professional technicians & DIYers to troubleshoot 3-70V DC vehicle electrical systems efficiently.
Sharp probe tip allows wire to easily penetrate and use in tight spaces. Do not use with household current of 110V/220V. This product is only for DC 6V-24V systems.
Also to inspect circuit tester integrity of headlights, taillights, turn signal circuits, faulty sockets, fuse connections and more. Constructed with premium ABS body with higher transparency, shatter-proof and durable.
✨ Flexible to use &carry: Extra long PVC spring wire increases flexibility range, and freedom when testing. a sharp stainless steel probe with protective rubber tip can reach into tight places and pierce wire insulation compared to cable wires, coil spring wires are lighter and easier to carry this does not need to take up too much space in your toolbox or any storage area.
BRIGHT LED DISPLAY & POLARITY INDICATORS: Features a high-visibility LED digital display with color-coded polarity indicators. This automotive circuit tester makes it easy to identify positive and negative poles for accurate readings even in low-light conditions.
Precision-designed circuit board generates much smaller current than normal test lights, greatly reducing the probability of damaging central computer board. This auto circuit tester ideal for checking various vehicles’ electrical circuits, such as car headlights, Taillights, fuses, car batteries, etc.
Automotive test light. Polarity indication: Red and green LED indicators help easily identify positive and negative connections. Suitable for testing various automotive electrical systems, including circuits in cars, trucks, and motorcycles.
Type: Digital Electric Circuit Tester. LED circuits board with micro current than traditional test lights, more secure and burn-resistant to automotive computer board. 【Quality Made】 Sharp stainless steel probe for piercing wires, also for hard to reach tight areas.
