Can a bad ground wire cause a battery to die?

Dead Battery A battery that refuses to take a charge is one sign of a bad ground. The ground is a major part of the battery’s charging system, so assuming that you’re getting proper voltage output from the alternator wire, and the battery isn’t hashed, then you may be looking at a bad ground wire.

Can a bad check engine light be a bad TPS?

The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.

What happens if the ground wire is loose in a car?

If the ground wire is loose, then the alternator won’t deliver its full power to the battery, particularly at idle. The simplest way to check for a bad ground is to run a continuity test between the battery and the chassis.
