I've got a 66 dart w/slant six. I replaced the distributor w/a Mopar-performance electronic conversion package, as well as the coil, and it runs great. My question is this: Do I need to replace the single-field alternator? And/or, do I need to replace the original voltage regulator? If so, how do I figure out the wiring for the dual-field alternator?

If the car is running great, maybe you don't have to change anything. The old electromagnetic regulators put voltage spikes in the electrical system. These spikes could cause problems with the ignition computer. Not having problems now doesn't mean you won't have problems some time in the future at a different ourdoor temperature or a heavier electrical load on the alternator. Then again, nothing I know says you ABSOLUTLY WILL HAVE A PROBLEM.

I've been told the new replacements for the old electromagnetic regulators are electronic, and some may be, but not all. I was going to buy a replacement recently, but the one NAPA had was electromagnetic.

The last conversion I did, I used the Mopar Performance voltage regulator for single field alternators. Mopar calls it a race only item, but I don't know why. It works great.

If you want to use the commonly available electronic regulator for the dual field alternators, check out the wiring diagrams at <A HREF="http://www.valiant.org/electrical-diagr ... ms.html</A>. There is a mistake, in the second and third drawings I can't get the web master to fix. The blue wire from the alternator field to the alternator regulator labeled "add one dark blue 18 gauge wire" should go to the ignition terminal on the regulator, not the mounting screw.
