can i wire it to either wire on the voltage regulator and...is it wired on the start circuit or is it wired from the ON position, I have a wiring diagram but I can't read it cause I cant find my friggin glasses LOL
 
standard 2 field wires off my 70 dart that uses the 2 wire regulator


in other words is the alternator exciter wire coming from the ignition supposed to be always in the ON position or is the exciter wire charged only momentary when the key is turned to start

at the voltage regulator does it matter which wire the excitor wire is attached to
 
You want to power Vreg only in the Run position (IGN1), not in Start (i.e. cranking, IGN2). No sense having the alternator fight the starter while cranking. The key switch only applies power to IGN1 or IGN2 at a time. As I recall, the blue wire to the triangle connector is from IGN1 (key switch). It should also go to one alternator field terminal. The green wire from the Vreg triangle connector goes to the other field terminal. Doesn't matter which field terminal, but you can find photos here if you want to be factory correct. If custom wiring (like it did) it is probably easier to install Vreg near the alternator.
 
Let's start as posted above with "what alternator?"

Mopar alternators do not have an "exciter wire."

Thank your sir that is exactly what I needed to know!!!
 

Thank you for proving my point. That diagram has nothing to do with any factory Mopar alternator,

Want proof? Go read a Mopar factory shop manual. That word will not appear anywhere in any Mopar manual which covers these cars

HERE is what you should be doing. "I" (which means ignition) at the regulator is spliced to either field, and this runs to the switched ignition on the "key" side of the ballast resistor. The remaining field goes back to the regulator. Make absolutely certain the regulator is grounded

I am not interested in a pissing contest here,move on please
 
Nobody is pissing about anything except you. If you do not wire this correctly it is not going to work correctly and will not regulate. If you like blowing up batteries, that is OK with me. Don't worry I won't be "bothering" you again.
 
67Dart273 is correct. He is also our resident electrical expert, so you should follow-up on anything he posts and be grateful. The alternator diagram in your link is for the Motorola design used in many GM's.

Mopar alternators are quite different and much simpler to understand and wire. My 80's Mercedes has the Motorola style and it confused the heck out of me until I figured out how the D+ "exciter" lead worked. Mine stopped charging since I replaced the dash bulb with an LED which didn't provide enough "boot up" current. Mopars don't have such issues.
