A bolt ect** A: Yes. Any metal that is attached to the frame. It should be cleaned with sandpaper or a wire brush first before you attempt to ground it. **Q: Will this work well on positive ground 6 volt vehicles on do you have a netter tool** A: If you can hold the prong on the “positive ground” and somehow make a contact from an alligator clip to the wire you are trying to test... then yes. But definitely that’s a huge flaw of that device. **Q: Does the screen update quick enough to read codes with obd1? the obd1 flashes power to the tester will it register the "flash"?** A: It’s not designed for that **Q: I purchased several test light assemblies, I am looking for the replacement electrical mechanism.** A: This one is very nice. ## Frequently Bought Together - JASTIND Premium 3-48V DC Digital LCD Display Test Light with 140 Inch Extended Spring Wire, Car Truck Vehicles Low Voltage Tester, Automotive Circuit Tester with Sharp Stainless Probe - JOREST 300Pcs Car Fuse Assortment Kit, 160 Mini Blade Fuses Automotive + 90 Standard Auto Fuses + 50 Micro Fuse + 1 Puller – for Car/RV/Truck/Motorcycle(2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A) - Premium LED Bulb Automotive Circuit Tester, 6-24V Test Light with 135 Inch PU Extended Spring Wire, Sharp Hard Steel Probe Vehicle Circuits Low DC Voltage Light Tester --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/81113482-3-48v-dc-automotive-test-light-140-in-extended-spring](https://www.desertcart.de/products/81113482-3-48v-dc-automotive-test-light-140-in-extended-spring) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-10-05*
