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

and is three pins

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!

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

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.

[Nacho-RT74]

actually, about my self doesn't care correctness about color or font on this item. The one I have is a generic piece. My concern was about the application crossover

[maxwellwedge]

Nacho's ebay listing is 1972 date coded.....no dimple

The second ebay listing is a repop.....no dimple

[charger500az]

This may sound dumb but I will ask anyway. How do I go about switching to an electronic regulator? Where is the best place to buy one and what other things do I need to switch it over? It it easy to do yourself. I'm guessing yes. Finally, how much easier is it to start your vehicle? I don't even have  a choke on my car and it's so hard to start in the winter. Need to get that fixed to. Thanks in advance guys.

[Nacho-RT74]

there are several topics around talking about that make a search and will find the info even with grpahics

[Nacho-RT74]

another yellow script piece NOS:

as the earlier one, not italic though

[maxwellwedge]

1974 over the counter part.

[Nacho-RT74]

well that prooves originally they were yellow and not white ? LOL

[maxwellwedge]

OK -  Let's discount the hundreds if not thousands of original tests and survivors that had them as the pic I posted. We will go with the ONLY magazine example of the yellow one with italic lettering on a pre-production prototype.

I will rip all the originals off my cars as soon as I get home today and throw them in the trash. I will also tell everyone I know with original cars to do the same.

[BIG ZAZA]

Guys 2 pages to talk about what color letters are on a voltage regulator.

Here in 1969 assembly line they were yellow.

1970 and 1971 assemly line were white.

And that picture of an engine compartment has many production line differences.

[maxwellwedge]

69 non electronic were yellow.....

[Nacho-RT74]

I'm just joking... I don't really care LOL, the main reason was already answered and poll is locked
