New style Alt, old style regulator
Has anyone tried or know if this will work.
I have a new style alternator and I'm wondering if you can pair it up with the old style regulator. The alternator is from a 92 Dakota 80amp and I was going to get a 70's/80/s style regulator to regulate the output. I have one friend that says the regulator will regulate any alternator as long as it is a 2 wire unit while another friend says the only way to get a new Alt to work is to wire it with the computer that it came with.
The way I was thinking was if the regulator regulates 14.2 volts would it matter what alt you have it working with it? Now that I've talked to another guy that's says 'no it won't work' it has me thinking.
Thanks for any input.

Re: New style Alt, old style regulator
Keith, you better do your homework on this. I believe that I read somewhere that the wire going to the amp gauge is too light to carry the extra current. I have a write up on it somewhere, I'll look and post it if I can find it.

Re: New style Alt, old style regulator
Yes Dan good point. I think I saw the same post on FABO as you mentioned and I should of mentioned that in my original post.
What I have done is run a new wire from the alt directly to the battery with a 8 gauge wire and I send no current through the dash as the original car. I am now using a volt gauge like newer vehicles do. I also upgraded the battery feed wire from the battery to a 10 gauge wire so heavier than original I think both those wires were handled by a 12 gauge on my 65 car.

Re: New style Alt, old style regulator
I hope I’m not off topic or stealing your thread.
Keith are you using a new alternator on the old motor? Just wondering how you adapted this alternator to a V belt type of drive or did you find a way to use a serpentine belt, I was going to,do this but there were no belts available for my application and i saw a post on fabo but still couldn’t figure out how to set it up and the fellow didn’t have a belt on it in his post
Thanks for any help

Re: New style Alt, old style regulator
the new style alt has a main feed and 1 or 2 field wires one of the 2 field wires is a ground same as the old style so it should work an alt is an alt they are all built on the same theory
now if it had a build in regulator that was only triggered by the computer then you might have problems .as far as the wire gauge goes this is an 80 amp and the stock one is 30 to 50 or so under load the factory wiring would be stressed for sure .

Re: New style Alt, old style regulator
Yea I upgraded the wiring to handle the new alt current to 8 gauge as I think the original is 12gauge. And I am running an 80 amp alt.
Dan I'll get some pics for you, I am running a serpentine belt so later I can run air cond fairly easily.

Re: New style Alt, old style regulator
Looks good, can you give me the part number for that belt as the part guy told me you can’t get that short of size and did all the bracketery allbolt on to the motor ok.? I have a magnum based engine as well going in my valiant and was going to use the alternator and ac bracket from the same style of motor you used do you think mine would bolt up ok and would it mater if the bracket came from a v6 or v8.
Thanks for your help

Re: New style Alt, old style regulator
Dan if you are going to run AC right away you will need a longer serpentine belt than the one I have in my picture.
The AC/ALT bracket can come from a V6 or V8 of magnum style motor (3.9, 5.2 or 5.9) and will bolt to a motor with magnum heads and a magnum style water pump. The bracket I used was from an AC delete truck but I have an AC/ALT spare bracket for later.

Re: New style Alt, old style regulator
Sorry Dan I forgot to give you the part no. for that shorty serpentine belt. This is only for the setup in the picture I provided with no AC and no PS.
It's from a 2001 GM T7500 Diesel truck , with AC delete.
Part no. is Ultra power K070553, and of course it's cheapest at Rock Auto.

Re: New style Alt, old style regulator
Thanks for the part no. I don’t know how you figured out that part no for a short serpentine belt as I couldn’t find any reference online as I’m going to fire up my motor with no ac pump that is why I wanted the short belt like you have I also noticed that you have a different pulley on your idler than is on my auto wrecker part that I have and did you just put the pulley from the tensioner in its place.
Thanks for the help Keith

Re: New style Alt, old style regulator
Yes I put a pulley from the tensioner on where just a smooth pulley would go as the belt would normally continue on to the ac unit. I just hope that I have enough belt contact area on the alt and it doesn't squeal like a pig when I fire it up. I think to find the catalogue for serpentine belt lengths I googled serpentine 7 rib belt length chart.
I was hoping to fire it up but clutch linkage is taking a lot of time to clear the TTI headers, had to order another clutch fork so I'm waiting on that.

Re: New style Alt, old style regulator
hey Keith that's a nice clean looking setup . I am just thinking of a way of making a bracket to adapt the tensioner to an L A style head but its not as easy as it sounds . it also looks like a magnum timing cover and water pump would need to be used .

Re: New style Alt, old style regulator
Aaron you defiantly need a magnum timing cover and water pump. I do have a set of old heads on the shelf so I'll try the tensioner bracket on them to see how easy or hard it would be to get it to work on old style heads.

Re: New style Alt, old style regulator
I sat in on the Mr Mopar seminar at Moparfest this summer and the best thing I got out of what was basically an infomercial was the Powermaster 1 wire alternator idea , it bolts right into our brackets , you run 1 wire to the battery and your done , no more regulator because it is internally regulated , all that extra wire can be scrapped cleaning up your engine bay .

Re: New style Alt, old style regulator
Wow thanks. I'm going to look into that as I had trouble with the charging using the magnum alt and the old style Mopar regulator.

Re: New style Alt, old style regulator
I bought the Powermaster and the heavy guage wire needed to use it but haven't made the swap yet , you need to do the MAD Bypass or something similar before using it because itbis a 100amp alternator and will fry your ampmeter and may cause a fire if you don't do the bypass or upgrade your wiring to handle the higher output . I'm looking at adding a second parralell set of wires to the ampmeter in my cuda with a jumper across the posts so the meter still functions , it won't read correctly but all it really tells you is if your charging or discharging so if it still goes up or down accordingly I don't care where it sits at rest .

Re: New style Alt, old style regulator
Keith and Cannucky, please keep us informed on how you make out. Maybe a diagram and description of what is required. This is probably an update that I should consider doing to my Duster.

Re: New style Alt, old style regulator
well theres 6ft of snow in front of my garage so it will be a while lol , the duster has a different dash and gauges but I know MoparWedden (John) didvthe MAD Bypass on his duster so you might google that for some diagrams and engineering advice .

Re: New style Alt, old style regulator
I have changed out the charging wire and bypassed the dash amp meter but I do plan on doing the MAD bypass when the car is on the road or maybe a voltmeter instead. My original magnum style alt is rated at 90amp so that is what I wired it for and I do plan on putting a fuse in line just in case.
The magnum style alt with built in regulator is part no. 433111 and at my local speed shop it's $529.
