Where is the battery positive terminal on an alternator?
Face the rear of the alternator toward you, and find the threaded stud and nut on the back of the alternator near the top—the location of the output (battery positive) terminal. The battery positive lead connects to this terminal via a ring terminal connector, with the nut holding it in place.
Where does the ground lead go on an alternator?
The ground lead attaches to this terminal. (Keep in mind that some alternators come without a ground terminal.) Always disconnect the negative ground terminal cable from the battery when working on any engine component. to minimize the possibility of shock and serious injury.
How does the voltage of an alternator affect the battery?
If you are able to look at a manufacturer’s diagram of the alternator’s connectors, the wire that slides over Pin 1 of the alternator leads to the positive (+) connection on the vehicle’s battery and senses voltage. If the voltage rises above or falls below 12 Volts, the alternator’s internal voltage increases or reduces power output…
How do I know if it’s the battery or the alternator?
Both of these car parts control your electrical system. However, your alternator charges your battery while your battery supplies power to your car. The failures of a battery are sudden, while failures of a failing alternator are slow. Always check your battery first, it can generally tell you which of these two is the culprit.

Can you wire an alternator directly to a battery?
If you try to run a cable directly to the alt you risk cooking the battery as well as frying the entire electrical system. Regarding this, what wires go to alternator? The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire.
What makes an alternator dead short when power applied?
Alternator dead short when power applied. ford alternator… Q: Alternator dead short when power applied. I have just installed a new 200 amp alternator with a Painless 10120 wire harness. When I check for continuity from the positive battery post terminal to the casing of the alternator or any area of the grounded engine block, I get continuity.
