electronic voltage regulator??

[krowbar]

Took off the top of my ' thought to be mechanical' voltage regulator and it has a circuit board in it...WTF I had a dual field alt hooked up with one field to regulator and other field grounded. Doesn't the elect. Reg use both field terminals from alt? I already fried one alt. I might have fried the regulator too? How the hell do I wire this in?

no...the single field regulators are for the single field alternators. You can convert the dual field alt to single style by grounding one brush lead. Common practice in the rebuild industry. Early alts are hard to come by and parts are harder to find for those. The elect regulator you have is a replacement for the points style.

To use your dual field alt correctly, wire in a 70 or newer regulator to the system. You will have to get a brush kit for the dual field alt in order to have both field terminals accessible. If you don't have a diagram, type in "Mopar dual field wiring diagram" into your browser and pics will come up, I can't find mine right now. (found it)

Does the electronic replacement of the points style regulator I have wire in the same way a point reg ie grounding out one field? Or would I wire it in to both fields like an electronic reg with the triangle connector?

 

[A383Wing]

the electronic replacement regulator that looks like the point style is wired the exact same way.

Do not wire it like the triangle style

How can I test that electronic style regulator to determine if it's working?

How can I test the ammeter in the dash to see if it's working without taking the dash apart?

Ok so I've done some probing. Ammeter shows discharge when I turn the lights on. Alt + post key off =12.62v. Key on =12.2v. Running =11v. V.R. ign side key off =0v. Key on = 12.06v. Running = 10.94v. V.R. fld side key off =0v. Key on = 0 v. Running = 0 v. Ballast key off = 0v. Key on = 12v. Running = 11v. Battery key off = 12.62v. Key on = 12.62v. Running =12.4 (12.3 w/ lights on) now when I check voltage at V.R. with ign wire hooked up to it, I get this V.R. not grounded to body w/ key on = 11.6v at ign side,fld side and base!!?? V.R. not grounded key off = .32v @ ign side and fld side. 0 v @ base. V.R. grounded to body w/ key on =11.65v @ ign side. 0v @ fld side & base. V.R. grounded key off =.29v @ ign and fld sides. 0v @base.
Any thoughts.....BAD regulator? One more thing. The ballast resistor is giving a 3 ohm reading when I test it.

stop testing and worrying about the ballast resistor......it has nothing to do with the charging system. You already know the resistor works because the engine runs.

sounds like you got a bad VR...you can get the electronic one that looks like the original points style at Auto Zone for around $25....I would start there...maybe have yer alternator checked as well. Or you could have engine running and put 12v to the one field wire terminal on the alt and see if it charges then. Pull the wire off the field term first
