Review on Green Power Probe IV with Case and Accessories - PP405AS: Multi-Function Car Diagnostic Test Tool with Digital Volt Meter, ACDC Current, Resistance, Circuit and Fuel Injector Tester by Erik Haynes

Ideal for testing voltage and resistance on or in conventional vehicles. Easy to use, comes with instruction manual, grounding clamp and fuse. It has a very long cord, so you can reach outlets from a long distance. In general, I warn you against using this tool on vehicles with control components such as new BMWs, Mercedes, etc. If you need to check voltage, voltage drop, or resistance, use a good quality digital multimeter. Large capacity DVOM. Do not use this tool for such applications. This tool is best used on older vehicles with very few or no modules controlling electrical components.
