Not sure if this is what you are asking about but a voltmeter can easily be wired in regardless of what charging system is installed. One wire from the accessory terminal or anything related to it is all that's needed and a good ground.

Hi I was not able to find any wiring instructions on the website you suggest---any help would be appreciated.Thanks.

Are you still on the Forum---I found it interesting that you are running a wire to a volt meter, not the GEN light. I like that. Any cpmments?Thanks. Harold

got it!

I installed a 10SI on my 55 Club Sedan... and used a Vintage Air bracket.

I installed the CASCO for the Thunderbird on my 56 Victoria. It was not “bolt-on” and I expected a few modifications. The original bracket between the ends had to be extended .300” to make the belt line up. The bracket mounting to the two water pump extension at the alternator had to be recontoured over the alternator fan for clearance. I also needed to make a 1/2” spacer at the rear. A 1” shorter belt was needed.
I liked the ease of the wiring and even tho it appears to be a single wire the connection for the gen light makes it immediately charging without reviving the engine.

For what it's worth, I've been using a one wire alternator for about 19 years.  I have a volt gauge, instead of the light and look at it once in a while.  I have not had one problem with it and this is a year round daily driver.  I don't think the concerns of a one wire are really going to be much of a problem on an older vehicle with a mostly stock electrical system.

Is the generNator the one made by Powermaster? I’ve been looking at those and the one wire thingy concerns me. I’d like my generator light to function along with other benefits of a three wire system.

Interesting stuff y’all. I have the alternator/compressor bracket set that comes with Vintage Air and Classic Auto Air systems. It’s a bit of a monkey motion looking setup that puts the compressor down low and the alternator up high. I don’t like the look at all.

I’m thinking seriously about that Powermaster generator looking alternator, and if they fit the stock brackets, My big issue with them is they’re one wire with all the drawbacks they offer. I will most likely go with it if I can figure a way around the issues. The wife wants to cruise this fall, so I’ll need to hook it all up with what I have and then revisit it all this winter. I like the stock look. I’ve gone through the trouble of hiding as much aftermarket hoses inside the heater and blower motor ducting, and having it duck out the bottom where it’s less noticeable.

What I’m going to do when I have the time to revisit this is use an original 56 factory air compressor bracket. I can mount a Senden on there as easy as anything. It sits up high, slightly to the right of the thermostat housing.

And one other thing. For those like me who care about such things, read this: Classic Auto Air advertises their “Perfect Fit” system to fit a 55-56 Ford car with no modifications. That’s not QUITE true. As it turns out, the factory Ford radio cannot be used with this system. Nowhere does it say this in any of their advertising. I actually drove to their headquarters myself as it’s only 5 miles from my shop and questioned them. I thought I had the wrong in dash unit. They printed a copy of my receipt, and there it was, on my sales slip “will not work with factory radio”. Needless to say, I was pretty darn upset. They offered me my money back, but I was already half through the installation. There’s about four inches of space so even a modern radio won’t fit.
My solution? I had an extra non working stock radio frame with the face on the shelf, so a few minutes with a hacksaw cut the front off and after cleaning, polishing, and repainting, I put it in the hole. My nice Town and Country radio is now in the closet. I’ll need to use a remote Bluetooth or some plug in jack for an iPod hook up I guess. That deal pissed me off more than it had a right to, but I don’t like purposely hidden surprises.

Anyway, onward and upward. I bought the Perfect Fit system because it was advertised as such: a perfect fit in place of the factory heat only system.
