Look for an ideal alternator reading of around 12.6.
What causes a short to ground?
Rodent damage, chafing wires, shoddy installation practices, water intrusion, and impact damage are just a few of the things that can interrupt your car’s electrical circuits. Inadvertently driving a screw through a wiring harness is a great way to cause a short to ground or short to power or both.
A dead short is a serious problem, and a tripped breaker can definitely be a sign that you have one. To detect a dead short in your house’s wiring, you’ll need to test the wires with a multimeter. If you get a reading of 0 ohms, then you have a dead short.
