How To Test Battery Ground Cable. Feel each battery cable after a run. This design is optimal for piercing a wire testing a fuse or checking the surface charge of a battery.
To find out clamp it to a ground source such as any metal surface on the car or the negative terminal of the battery. Fuse control module from the suspect circuit. Again you should see a reading of 03 volts or less to be.
Over time the vapor can begin to corrode the terminal and cause corrosion to.
Clearly it should be a lot greater than 4 ohms. Ground fault detection systems provide a means for indicating or measuring current leakage paths between ground and the positive or negative terminal of a battery or battery charger. The simplest way to check for a bad ground is to run a continuity test between the battery and the chassis. If you are using a multitester set the tester to read voltage V.
