 Hello all. I'm new here and still trying to find my way around. I'm also new to rebuilding fans. I recently came into a
pretty tired looking, at least on the outside Emerson 79648 AP-G. The fan was non functional when I got it and someone had go through it and cut just about all the wires.

I tried searching for this topic but could not seem to find anything so double apologies if this is redundant or too remedial...

I've seen the diagrams for similar Emerson fans here and while they make sense I'm a little confused as to where the initial 120 AC connections are, or more precisely where one of them goes. In the diagrams I've seen there seems to be a connection or connection post on the upper right corner of the speed conrol looking at it from above.

The speed control I have has a plastic( phenolic ?) plate where all the connections are but in that position all there is, is a hole. It looks clean as if there was never anything attached there, no marring at all. I'm not sure what the rules are for posting photos so I'll try posting a top and bottom view... I guess the other way to ask the question is will it work to run one side of the AC input directly to the midrange connection ("B"?) on the stator?

Yeah I know I need a fans for dummies book.

Thanks in advance.

Jerry

You need a capacitor also with that model .
Some on should  give you the wiring and r a link for it.
Welcome to the forum .
 Remember there are no stupid questions!!
That will make a nice fan when you get up and running.
the AP-G stands for government.

Thanks Charlie. I have the original capacitor which I was able to check and shows 2.6mf, in fact the fan while beat up seems complete. I checked the resistance on the windings and they are close to what I read they should be.

I'm just missing one threaded hard bushing and the special screw for the oscillating function. I will try to make both.
My greatest challenge I believe will be to straighten out the fan cage.

I just want to make sure I don't dumb thumb anything if I can avoid it.

For this first fan, for now anyway I'm going to use contemporary wire, no fancy period stuff although once I had a lot of cloth wrap wire from my late dad who was a long time HAM and had stuff back to the 20s. I just could not keep everything and still sleep in my home.

Jerry,
Some of the guys  use a hook   in the basement joist or where ever  you can  mount one solid and  you can put the cage on it and work it around with your hands.
I live in a double wide so it has a trailer frame and I just wrap a short chain around  one of the beams,just get it solid.
You probably know if the old cap looks leaky a or bulged replace it. Take your time !

Well I noodled it out. The old girl is running well. All I need do is make some felt disks to hold lubricant in place, balance the fan blades, make a shoulder screw for the oscillation function  and finish straightening out the fan cage then she will be right as rain. Runs whisper quiet.

There's the potential for more of these or similar and now I know more or less what I'm up against.
