What would cause a bad ground?
Paint, corrosion, greasy surfaces, frayed or broken wires, and loose connections are the main cause of bad automotive grounds. Some vehicles use a separate body ground wire, besides the main ground (black battery cable), that runs from the battery negative terminal to the chassis.
How do you test an outlet for bad ground?
Pull the red probe out of the small slot and insert it into the ground hole. If the circuit tester lights up then the outlet is grounded but the wires for “Hot” and “Neutral” are reversed. Repeat this process to test all of the outlets in the room for a bad ground.
How can I find out if my engine ground circuit is bad?
There’s some unwanted resistance in the ground circuit. To locate the problem, continue with the next steps. Move your meter’s red lead to the main ground terminal, engine end side. Have your assistant crank the engine while you take a voltage drop reading.
How do you find a bad ground with eHow?
Insert the red probe of the circuit tester into the small slot on the outlet. Insert the black probe into the large slot on the outlet. The circuit tester will light up if power is being sent to the outlet. Remove black probe from the large slot and insert it into the small “U” shaped ground hole.
How can you tell if a car fuse is good or bad?
Include your email address to get a message when this question is answered. Regarding car fuses, most cars use a colored ‘blade’ type fuse, and looking at the top of the fuse in situ in the fuse box will show that the metal strip that runs along the visible top of the fuse will either be intact (fuse good) or broken (fuse blown). Thanks!

Can a bad ground connection cause an electrical problem?
An electrical problem can often be traced to a single source: a bad ground connection. A bad ground can cause noise in an audio system, make electric fuel pumps run hot or produce low pressure, and make electronic engine controls do weird things.
