I am putting the electronic ignition conversion in and need to know if I have to buy an alternator with an internal voltage regulator or if the current external voltage regulator will work. I'm putting this engine in the car and getting it to run so I can take it to the DMV and get it titled. It will be trailered, not driveable and I want it running for the inspection. Any advice will be greatly appreciated!

you'll be fine as long as your external regulator is solid state.

What Drift said, get an electronic reg & make sure it's making good ground contact. An electronic conversion will run with the OE electromechanical reg but the voltage spikes from how it operates ain't good for electronics plus they've been known to stick & full field the system.

Ran them in 3 older Mopars.Now the 62 has full MSD as does my 65.My kid still runs the 62 alt and new style replacement electronic reg that looks like stock.Its been that way for 12 years.My 65 I have the square back and newer style reg.Been in for 13 years.Rocky

Thanks! I did some looking and it seems there are two different regulators. One looks like the older style and one looks similar to the ECU and requires a special connector. The price of the older style one is more than a new alternator.... Am I missing something? The newer style regulator is pretty cheap...

Depends on what type alternator you have, 1 field terminal, or 2 field terminals?
The regulators will be different for the 2 types of alternators.

Here's what you need! Hope this helps you out!!

What year vehicle? If it's a 69 or earlier with the "box" reg with a terminal on each side then yes (A) just get the electronic type replacement & someone on Moparts sells an electronic reg with a black cover that looks original if that is important & I think someone said the OE black cover will fit it for even more originality. If you have a later 2 field terminal alt with the (A) reg (OE electromechanical or electronic) just ground one of the alt field terminals. FYI if you have the later 2 field terminal alt & a '70 up "flat" reg in your stash you can trim the sides of it & redrill 1 mounting hole & it will nestle neatly into the firewall recess where the OE "box" reg once resided, just need the extra wire from the triangle reg connector to the 2nd field terminal on the alt (1 blue/1 green) & this may be the one you are referring to as looking like an ECU (it's ~half as thick as the ECU & has a triangle shaped plug in)

RR I think from his sig it looks like a 68.He needs the points looking type if it still has the one field wire alt.No need to run wires and drill holes with the electronic reg that replaces the old points type.Rocky

Yes an electronic "box" replacement reg would take care of this real easy & from what I understand most of the replacement "box" regs are now electronic but I'm not sure on that.

Thanks again! I'll look and see if I have any of the regulators that are electronic but I don't think so. I have several alternators and I need to check the date codes to see what they are. I'm not concerned about it looking original I'm looking for it to function. The 440 is a 74 and the car is a 68. Just trying to marry them up so it will run and the car looks complete for the people at the DMV so I can get it titled. Thanks again for all the help!

Thanks again! I did some looking at the voltage regulators I have and took them apart. Just so happens one is the electronic type. I wouldn't have known what to look for if it hadn't been for you guys! Thanks again!

Easy to spot the electronic reg that replaces the points type.Its almost flat.No need for a tall cover.You can take an old cover and use it on them though so it looks stock.Rocky

ELECTRONIC TYPE VOLTAGE REGULATOR

i have a new one, delco remy brand,you pay postage and its yours...

Joe thats the later style.Talking about the new replacements that look like the points type.The kids 62 is still running the OE alt with one.Been going strong for 14 years.Rocky

I'm not sure what all the fuss is about re electronic ign and mech regulators. I suppose there could be some RF interference from the points that might cause the the ECM to malfunction but I would think the 2 boxes would have to be mounted beside each other or the ign wiring harness laying against the regulator for it to happen. My 66 ran just fine with the mechanical one and an MSD system.

After I upgraded to the isolated field/electronic regulator, I had nothing but problems with the charging system. An internally regulated Denso alternator cured all that.

Me? I would install the electronic ign and see how it runs and then decide whether it needs a new charging system.

Make sure the air gap on the dist pick-up is correct (.008?) if it's an MP kit as they are known to be WAY too wide OOTB and will either not run at all or run badly.

This is what I got to use with my electronic ignition.

The reason to use the new electronic reg instead of points is because they charge much better.Typically you dont have the light flicker and dimming.Plus no points to stick or burn.Ive driven Mopars since the 60s.The replacement reg is one great part.They also charge better than the points.The reg in the picture might be one of the new ones that have the large cover.Look at the back.If there is a resistor its points type.The replacements attach just like OE but are maybe 1/2 to 3/4 inch high.Rocky
