Electronic regulator

[Nacho-RT74]

P4529794




or P3690731




I know the blue one is stated FOR RACE USE ONLY.. but I have known several guys have used on regular use with good results. I got both

[ODZKing]

Unless you're racing it ... I'd go with "correct"  

3480150 = P4529794

[Plumcrazy]

First one.

[tan top]

first one !!  P4529794      

have  read & heard the blue race only ones heat up the coil & reduce its life 

[Nacho-RT74]

why? the coil has nothing to do with charging

[Ghoste]

I'd use the correct one.  Do you really need the constant output one?  (other than its intended application)

[tan top]

not  100% on this Nacho  just trying to remember something that i've read , many years ago   on the over heating the coil  with the race only regulator !! ,  think  the race regulator  keeps the voltage as   minimum of   13.5  or something similar 

[68neverlate]

I like the look of original, so I'm with everyone else on this one.          

Not meaning to steal your thread at all Nacho so please      me if I'm out of line, but, what would a racing voltage regulator do for you to get an "edge" over stock?  If you wanted to run a hotter spark wouldn't you just upgrade your ignition and/or coil instead?     

All I can see a "racing" voltage regulator doing is putting a higher voltage to the field and possibly increasing the overall power output of the alternator.  And if that's what you were trying to achieve, wouldn't you just upgrade your alternator instead?  Just wanting to confirm my understanding of things...

The "correct one" should have white lettering......But I'm splitting hairs

[Nacho-RT74]

I got both because being overseas wanted to test both on same shipping.

I like more the yellow one... and I have seen NOS yellow ( real NOS ) not white

why my question? because I have known several ppl using the blue one on street with success and without any fail on anything else, so just wanted to know your thoughts

[ODZKing]

I just looked at the one I just purchased from Chrysler (dealer) again and my mistake, it is black with yellow letters and 2 pins as pictured

Assembly line were white lettering and "ELECTRONIC" was not a slanted font. They had a Pentastar and didn't say "Mopar" on them. The Yellow can be NOS but have later dates on them. Originals all have a round dime sized raised "dimple" on them. Not sure after 71.....I guess they might of been yellow.

Here is a better pic of the original style. 46th week of 69 date.

welll actually look at this:
http://www.ebay.com/itm/360241737227?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

and is three pins

[gtx6970]

The 3 pin one is some weird one for 1969 Imperials only,,,, I think.

1970 and 1971 or so were white print.

similar to this one

Then sometime in the early to mid 70's Mopar used this same print style but with yellow print color.
Reason I say this, is there is a 1975 or 76 duster I used to work on that had one. And it was dated correct for the car.

[gtx6970]

These  Later Mopar perf versions with the MOPAR in block print is an over counter release that ( afaik) is not OE correct for any vehicle

[Nacho-RT74]

welll actually I didn't care about correctness on this

I was wondering WHY there are two diff versions one is MP and the other one it looks is not not as far I remember. I remember have seen two diff PNs for same black box... not the printed PN, I mean the service ( labeled on package ) PN

got a picture saved  , just for reference

[maxwellwedge]

Yes - They both have different part numbers - good post TT

Bill is correct as to the 3 pin being an oddball....Imperials - maybe......truck - maybe. Not right for our stuff though.

[nascarxx29]

If I can find the issue or 1970 cars magazine Im pretty it was in there.They did a 70 V code charger roadtest.The vintage engine compartment picture though reversed image .Showed a yellow lettered voltage regulator

[maxwellwedge]

No way - No Sir!

If it appears yellow then it is the filter/ age/ lighting of that shot.

[UFO]

This one?

[Nacho-RT74]

and ITALIC characters too... sure everyone shows its differences

[nascarxx29]

Thats it thats the picture flipped image and yellow voltage reguulator

[gtx6970]

No way - No Sir!

Magazine car is most likely a pre-production or pilot car and probably should not to be used for restoration purposes

Yes to that.
Maybe the regulator was replaced with a parts department piece before that magazine got the car. The non assembly line over-the-counter parts were perhaps in the dealer stream already. I have seen original magazine tests with parts department batteries.....let's face it - stuff failed.

I'll be happy to invite you all to look at date coded originals still on the cars.
