alternator

[rattlesnake]

Guys educate me please. Why does an alternator (an appliance that is supposed to PUT OUT electricity) need a 12 volt feed (by feed I am assuming they mean hot wire)

I currently have a square backed Chrysler alternator. My schematic shows a blue wire and a green wire going to the fields on the alternator and the wire going to the batter post on the alternator. I am good on the green wire, The only blue wire I have is coming off the ballast, it is running to the coil. Am I supposed to splice off that blue wire and run it to the alternator as well as the coil???

Does the voltage regulator HAVE to be grounded to the firewall???

Yes, Also ties in to pin "23  on on bulkhead plug, Coming from other side of voltage regulator. Make sure to put in proper place on Alternator.

To sense the signal from the voltage regulator to turn up the charge to recharge the battery & turn down when the battery doesn't need charging.

The voltage regulator doe require a good ground from somewhere, the firewall is where the factory put them.

I do not have a electronic control box. The wires come through the regulator/ballast, to the alternator and coil. I am running a unilite distributor. Does this change anything in the diagram?

Since I ran a unilite before I can tell you that it needs it's own ballast resistor to drop the voltage down to like 7-9V for the module inside the distrib, anything over that and it fries. Guess what a replacement one can be had for $150 bucks but that was told to me years ago.

Basically you have to spin a magnet in an electrical field to create power so the feed is to create the electro magnet
