What is stator terminal on alternator?
The STAtor terminal is connected to coil output before it gets to the diodes, so it puts out an AC voltage. Among its uses are as a tach signal, or to power electric components that can run on AC, such as the choke heater.
What is the wire that turns on the alternator?
• B is the alternator output wire that supplies current to the battery. • IG is the ignition input that turns on the alternator/regulator assembly. • S is used by the regulator to monitor charging voltage at the battery.
Where do you put the wire for a new stator?
The wire marked red (coming from the engine) in the diagram is going to attach directly to the contact breaker points. There should already be a wire connected to the breaker points right where we need to put the new one. You need to remove that old wire and put the wire for the new system RIGHT WHERE THE OLD ONE WAS.
Do you need an alternator in a 1960 car?
Vehicles older than a 1960 model may require all of the connections of the alternator, except ground, to be connected to positive and negative terminals of an external voltage regulator instead of directly to battery and ignition connectors.
Is it good to have ground wire from alternator?
As long as the part in question (alt) is grounded through it’s case to the engine , and the engine itself has a good ground to the battery , all should be good . But , in many cases , over time those connections get corroded , just like the battery cables .
Where are the wire connectors on an alternator?
Inspect the back and sides of the alternator to locate the two wire connectors. One of the connectors is typically a threaded bolt protruding from the back (the opposite end from the pulley) that a wire with a boot on the connecting end is snapped onto.

Are there any disadvantages to one wire alternators?
Another minor disadvantage to one-wire alternators is the rotor in the alternator must achieve a certain speed to self-excite. This usually requires the driver to rev the engine to increase internal voltage to sufficiently excite the alternator to begin charging.
What to do when your alternator is not working?
With the engine idling at operating temperature, turn on all the electrical components such as the headlights, blower motor at full speed, four-way flashers, electric fans, and the stereo at a reasonable level. Then, note the electrical system operating voltage.
