Location: Woolwich Twp, NJ (South Jersey)		What engine etc...? I just got my 354 running with a Mopar alt, BBC water pump and big block Mopar P/s pump. If you have a 354 / 392 I have a recipe and pictures plus I worked out a wiring diagram. I may have posted pics on the site.

Location: Hay Lakes, Alberta, Canada		Anyone know anything about those new "altergens"? They are an alternator built to look like a generator? Supposed to fit in with no modifications to brackets...

Location: Perth Australia		I have read about them as well and being an auto electrician, I am very curious as to how he does it. I do not know of any off the shelf alternators that you could raid to get the expensive parts to make that would fit inside a generator carcus.

My thoughts are that they are so expensive because of that.

I also have not seen what their current output is, but I would be surprised if it was much over 35-40 amps. Still better than a generator but nowhere near as good as a modern day alternator.

I dont know why people are keen on single wire alternators though, The gen to alt conversion (wiring wise) is pretty simple. This still lets you have your warning light working

Generators with power steering pump or tach drive attached to the rear end cannot be converted to a Gener-Nator.

Location: Perth Australia		I should look into that idea Loyd

Some of the little buz boxes that are around do have small Alternators but I still think they are a bit big.

I do have the resoarces to check though.

Thats what I need, another project lol

Location: Woolwich Twp, NJ (South Jersey)		Attached are photos of the setup I have on my 354H. I am running a Chrysler 2 sheave alternator (2 wire), using both sheaves; BBC water pump with adapters and a B/RB block P/S pump. The water pump pulley is 2V, 5 7/8" diameter x 1 7/8" set. The crank pulley is 3V, 7 1/4" diameter x 3 3/8" set. The W/P pulley has a 1" spacer block and 1/16" W/P pulley shim. The crank pulley is directly bolted on. The alternator has a 1/16" stainless steel washer between it and the water crossover. The alternator bolts have modified spacers with long bolts to the W/P and block. I modified a piece of flat plate and tied the (2) water pump bolts and (1) alternator bolt together. Hope this helps. Mike

any info on brackets for either the GM 1 wire or for the Mopar alternators.


For a gm 1 wire you will have to fabricate brackets.... for a 60's era alternator you might be able to get the brackets
from a small block to work on your engine.... you should if you get the brakets for a poly.

The GM 1 wire is the easiest to hook up.... the 3 wire mopar alternator is very easy as well and as you say it lets you have your light....

On the mopar alt you have the batt term which goes to the battery then 2 fields wires. With the old voltage regulator.... the top field wires goes to the
voltage regulator and the other side of the regulator goes to switched 12 volt ignition. The other field wire goes to ground.

With the new regulator the top field wire goes to the middle pin on the solid state regulator and the switched 12 volt ignition. The bottom field wire
goes to the left pin on the solid state regulator. Simple..... plus you wont need to fabricate brackets if you use a mopar alternator.

Check out the wiring diagram

Location: Woolwich Twp, NJ (South Jersey)		If this can help; below is the electrical conversion diagram for my '56 NYer. I converted the car to an alternator, electronic voltage regulator, electric fuel pump, MSD distributor and late model Torqueflite. An oil pressure safety switch is included with the fuel pump circuit. I reused the horn relay, starter relay, and dashboard switches, etc... Regards, Mike

Location: Blythewood, SC		Have you considered shunting the primary lead off the alternator so it does not travel through the ammeter? I have seen a lot of burned up ammeters, which leads to a dead car, when it's wired that way. It seems to be more reliable to keep the high amp load out of the guage.

Location: Woolwich Twp, NJ (South Jersey)		I was aware of the ammeter issue when I was working this out. An electrical engineer (Mopar dude) marked up this diagram for me and added the 30 amp fuses. I am an electrically challenged mechanical engineer.

50002000100010010010010025
Location: Perth Australia		I just looked at your schematic

you have a 30A fuse in the line out from the ammeter to the battery

But your alternator has an output potential of 65A

You need to replace that 30A fuse with a fuseable link wire

The fuse size required needs to be 25% larger than the current draw or in
this case current produced

To qualify the above, you also need to be sure that the components between the alt and battery are also
strong enough to handle the current

This is where meltdowns will happen

Location: Central NJ		If you have to fabricate your own it is not terribly difficult. Her is a pic of the cardboard template I made to mount a GM high output alternator onto an LA small block that's going into 56 dodge. I used an original bracket and copied the dimensions of the original mounting points at the water pump.

And the finished product.
