Mopar Performance Electronic Conversion Kit: P3690427?

[a6t9vette]

I recently bought a used Electronic Ignition conversion kit and while looking for the instructions on line, I found one site that said to install in a 69, or older the "voltage regulator MUST BE REPLACED with a Mopar Performance regulator DCC-3690732". The installation guide does not mention this, and I cant seem to find any other site that mentions it either.
Has anyone here installed the kit and did you need to replace the voltage regulator?

Thanks

Yes, you will need to either change to the blue Mopar Perf regulator or go to a 70 and later regulator and alternator. Another option that should work is to upgrade to an electronic regulator.

The old regulator is a points style that doesn't deliver a constant voltage to the charging system. The electronic regulators give a constant output that your ignition needs for a long life.

This is what I did for a regulator that still looks stock.

John when you did that mod to the Duralast VR706 did you have to change out your alternator? Since my car isnt really 100% stock cost is probably a bigger factor, and having to change the alternator would be a bit expensive.....

 

[Big John]

Nope, that's for the single field 69 and back alternator.

Great thanks, I'll pick up the VR706. From what your saying thats probably the easiest/cleanest/cheapest option. Doesnt happen very often that it works that way. Do you have a picture of your entire installation for referfence?

 

[Big John]

Sorry, no pics of the install... My car is still in pieces.... Lots of pieces.

John as a follow up, how did you select that voltage regulator? I found this one, but cant find specs on either to compare. I assume there is an input/output requirement that is required. This looks like a form/fit replacement as well.....

I found it through a search at Autozone.com for a replacement regulator. The mounting footprint, electrical locations and bracket looked identical except for the overall height.

While I never found any other specs, the 69 and earlier regualtors are pretty much the same across the board. Unlike the 70 and later which controls negative to the alternator, the earlier ones control positive to the alternator.

So if its a replacement for a 69 regulator (the only in the above link claims to be as well) it seems strange why it would be need to make the Electronic Ignition work, where the OEM one would not.....

But hey if your running that set up and it works, im not going to argue.

The big difference is the VR706 is an electronic regulator like the MP regulator. The key is to get away from the old points style that just won't work well with the conversion. I honestly can't remember where I verified this... I think it was through an internet search for the manufactuer. Of course... just the size gives it away as not having the points and coil in it.

There was an article I saw about doing this (after I did mine) and they cut the top off the VR706 and replaced it with an older top. It was clearly an electronic regulator.

I also used the MP blue regulator on the first conversion I did. It worked fine.

Actually, my car has used an MSD-6A for years now. The plan now is to use a MP distributor and no ballast resistor (except for looks) and to hide the MSD box.

My car had the conversion and an old style reg until very recently. There is a chance that it is some sort of updated guts deal.

I still have it, maybe I can look and see if there are any clues.

It worked well, I only changed because the new engine harness came with the updated reg wiring.

Now that sounds like the hot set-up if you're trying to keep it looking stock...Do you recall any other details? Might be interested in doing that myself...

IIRC, they pried the covers off and just switched them. I thought about trying to do that, but I cut the cover from the old one and just epoxied it on top on mine instead.

 

[SomeCarGuy]

I would rather glue one on than to cut it off and hope the new one seals as good...

The biggest advantage I noticed after getting away from the points type reg. is there is no more discharge at idle.

Sounds like someone had a "discharge" problem.......

Before I found I had a bad alternator, I opened up the regulator to clean the points in it. Much to my surprise, I found it had a circuit board in it. The cover looks just like the original. Also, I replaced the points with an Accell pointless conversion kit. The only way you would know something is different is that there 3 wires coming out of the distributor instead of one. It has worked great, and I think it starts quicker now then it did with the points in it.

I just went with the 70 style. :leave:
