Where is the ground wire from the alternator?
The alternator is mounted on the engine and the engine should have a ground strap to the frame. From the frame there is a ground strip to the battery. That’s a long way for a ground circuit.
Where does the alternator go on a truck?
The body of the alternator is ground. The alternator is mounted on the engine and the engine should have a ground strap to the frame. From the frame there is a ground strip to the battery. That’s a long way for a ground circuit. Works fine when the truck is new but after 30+ years you’ll have all kinds of corrosion on metal parts.
Where is the ground wire on a car?
Look for a separate wire with a wire terminal on the end. It is the only other separate wire without a “boot” on the end of it, but rather a round slide-on terminal that slides over a bolt connected to the vehicle’s frame. This connection is “Ground” and completes the negative (-) voltage side of the electrical circuit.
What kind of wire should I use for an alternator?
This is the IGN wire that should be 12V when the key is in the ON position. * White/Green stripe. This is the Field wire. This wire should be around 12V as long as the battery is below 13.6V. This wire “regulates” the output from The alternator. * White/Black stripe. This is the ground wire. Not important at this moment.

How do you connect a charge wire to an alternator?
If you want to use it as a one wire, connect the charge wire to the battery and alternator and you’re done. If you wish to use the three-wire system, connect the charge wire, remove the black plug at the two-wire terminal location and plug in your wiring. It’s that simple.
What are the three types of wire in an alternator?
The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter. The voltage sensing wire connects to the battery, and the ignition wire connects from the alternator to the key switch.
