Hello I was wondering if anyone could tell me if this alternator was ever mass
produced and if so,what year and/or make of vehicle.
I would like to try and get one of these for my dart at the wreckers,but need to know what vehicles they came in.
Can anyone help.

Thanks

Duane
 
I have one that came off of a 22R in a Nissan pickup from the early 80's. Not sure if it's the smallest tho?

That's great if you're running a big block. Still need an application for the alternator. I can buy rebuilds cheap locally, if I know what I'm looking for.

ive got a denso alt. that i took off of a acura legend.....dunno if its what your looking for......how do you make this work on the mopar stuff..(wires) i can make the brace to fit i think.....
 
There are denso alternators for sale on Ebay that advertise 60 amp, with one wire hookup. I don't know if they are all that way, but I would think that would be pretty simple to install.

EDIT NOTE: when I looked at the diagrams harder it was the 102mm alternator at 6.78 lbs. So I don't have a lead on original application on the 5.68 lbs unit.

I got the 102mm mini from like a 87-90-ish? Chevy Nova/Spectrum with the single groove steel V-belt pulley. Got it from the junkyard. Tested fine. It is the same physically as powermaster p/n 8122/8128 6.78 lbs. 102 mm. ( http://www.powermastermotorsports.com/denso_alternators.html ) They are not one wire stock. But they have an internal regulator.

I have yet to install it or really spend time trying to figure out the fabrication of the brackets.

I don't think AREngineering does not make a bracket for that alternator with mechanical fuel pump and 69 down water pump.

Those are the smallest alternator advertised on the Powermaster website. We use the ultra mini powermaster on our Circle Track race cars.
 
Not positive of the year, but I got a 90-120 amp Nippondenso alternator, from a junk yard for my 66 Cuda slant six. It came off a dodge pick up, wth a small block V-8. Don't remember if it was a D150 or a Dakota. It was either a 88 or 89. The early model had the V-belt pully, and the later ones had a multi rib pulley. The pulleys can be swaped. These can be installed on any Mopar using the stock external voltage regulator for the car.
 
I have 2 that came off 87 to 89 Honda Accord.

Most of the Denso alternators are the same electrically. The main difference is the output amps 90-120, and whether it is internally or externally regulated. The biggest problem is the mounting. There are many different mounting configurations. I would suggest you look at the late 80's mopar small block trucks. They might be a "bolt on" for your engine, if you use the donor vehicle mounting brackets. These will also be a straight wire for wire hook up. Just remember to upgrade the wireing to a larger size between the alternator and the battery, and bypass the amp meter. The factory wiring and meter was not designed for that amount of amps.
 
I use a Denso 90 amp unit off of a Bobcat. One wire hook up with my own fabbed brackets mounted low on the left side. You can see my older Nippondenso 40 amp unit mounted in this pic. I didn't need to change much to mount the newer 90 amp unit but I don't have a pic of that yet.

The alternator you're after is from an '88-'91 Dodge Dakota, D-series truck, or B-series van with a 3.9 V6, 5.2 V8, or 5.9 V8; or an '88-'89 M-body (Diplomat, Gran Fury, New Yorker Fifth Avenue, or Canadian Caravelle). It has the V-belt pulley you'll need, and electrically it'll hook up to any earlier Mopar regulator. If you're using the '70-up electronic regulator, just connect one field wire to each of the new alternator's two field terminals. If you're using the '69-down regulator, connect the one field wire to either of the alternator's field terminals, and ground the alternator's other field terminal. You will need to do some bracket adaptation, purchase new brackets if you're running something other than an LA engine, or use the '88-'91 brackets if you are running an LA engine. You will also need to consider the effect of this alternator's higher output on the rest of your electrical system; see this post and here for more info.

Why did you switch out the 40 amp unit?

Was that a smaller or different bodied alternator?

Did you buy the 40 amp aftermarket, like powermaster, or did you get it off an original application? If so, what application/car did it come from?

I believe the original question was to find the OE application of the Ultra Mini Denso alternator. I assume that is the Powermaster PN 8162 (93mm) alternator.

Duane, is this the alternator you are asking about??:

I'm looking at adapting one off of a Toyota brand forklift. An older one off of a 7 series model are rated at 37amps. My plan is install it on my drag race car.
 
I must not be getting it. Besides going down to one wire, what is the benefit to this? I have probably 8 good spare old MOPAR distributors, I say good because I tested the on my car 3 years ago, that I've taken off cars that I stripped so it's not like I'm short on spares. So basically I guess I am asking for somebody to sell me on these things.

Most guys want lighter weight higher output altenaters for electric fans, fuel pumps, sterios, whatever.
My idea is to mount a smaller altenater infront of the mechanical fuel pump, then mount a samll a/c compumper where the altenater was. May not be possible but worth a try. I'll probably need to delete the mechanical fuel pump and go electric so I've bought the delete plate already.
One piece I still want to play with is the heavy altenater mount from a 66 and earlier 273 ( foundation for the a/c pump ).
 
Thank you for the info RedFish and I appologize for hijacking your thread for a short time Duane.

OK, in order, the 40 amp unit was keeping up the electrical system but was not really charging the batteries. 12.87 volts at the batteries.

Yes it's smaller.

The 40 amp unit came off of a mid to late 80's Colt.

The 90 amp unit provides 13.87 volts at the batteries. I used 8 gauge wire instead of the 10 that came in the Painless harness but it's still a long way back to the batteries.
 
Yes this would be the one I am after. 93 mm.
What OEM vehicles came with this alternator.
