The other terminal is the exciter. This exciter circuit is a “load” per say, that has to be there. Right, but where do you test for the voltage, in the connector going to the alternator?

Excitor Wire Is Needed To Generate The Voltage Required For The Alternator To Start Running.


This should help get it started but alternators do sometimes need a certain speed to kick on and. For an alternator you need an exciter circuit to start the coil (windings) to produce a field to start the alternator to produce charging. Additionally, there are other components such as floor, switch, motor, and inductor.

Lastly, You Need To Wire The Exciter.


Run the exciter wire from the run position of the ignition switch through an idiot light and to the alternator. The other terminal is the exciter. It is used to excite the field windings of the alternator, which in turn creates the amount of amps.

These Instructions Will Likely Be Easy To Grasp And Use.


The main purpose of exciter in a generator(alternator) is to provide stationary rotating magnetic field. Please refer to the manual and wiring diagram that came with your alternator for more specific details. The voltage regulator's job is to supply voltage to the battery when it's not at the nominal level.

Wiring Diagram Comes With Numerous Easy To Stick To Wiring Diagram Directions.


According to earlier, the lines at a alternator exciter wiring diagram signifies wires. Description generally, three wires are connected to an alternator, including the exciter wire. It requires minimal voltage to excite the fields and the voltage regulator decides that voltage.

This Exciter Circuit Is A “Load” Per Say, That Has To Be There.


But in modern vehicles, the alternators have regulators, and most don’t require an exciter wire to function. The alternator also shows a connection with the ‘battery charging wire.’ Its the blue wire going into the connector correct?
