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.
Are there any myths about grounding a guitar?
There are a few Guitar Grounding Myths that we want to dispel: MORE IS BETTER: Definitely not. Proper grounding means it only needs to connect correctly to the ground once. Grounding items multiple times creates a few problems. For one, using wire to ground a series of pots in a circle creates a one-turn coil.
What should I do if my battery ground is not working?
If your accessory still doesn’t work properly after redoing the grounds, you will need a voltmeter or multimeter to trace the wiring. Set the voltmeter to read ohms (resistance) and probe the battery’s negative stud and ground connection on the accessory (the ground terminal on an amp, for example).
