Vintage Alemite Electronic Wheel Balancer

[Plymouthy Adams]

I have on hand a vintage wheel balancer.  I picked this unit up years ago and never have messed with it.  Heavy unit and would like to check it out but some conflicting data at present, wired at plug for 110 but data tag says 230.  The data tag is the cover to the electrical contact field for wiring and under the lid is small schematic.  Sadly the schematic is messed up in the middle section to the point I cannot read it.  Inputs are shown but does not indicate that 230 by lack of noting line 1 and line 2 inputs.  There is a note below that I cannot read but think it states (double motor) The spin motor is a Lamb (Ametek) 1s14790 where the first digit could also be an I possibily.  It is an AC brush style cast housing and well made.   Nothing on the internet come close to this motor by number or image search.  Stuck on this one a bit.  

 

Question for the masses, does anyone have one of these in captivity that could remove the cover and scan/photograph their schematic...or...even better, the odds of having a book on hand with a schematic inside.    Operation manual I did find searching but nothing on wiring at this time.

 

Reaching out on this one and hoping for the best....thanks for your time.

I have the same dang issue. My compressor is 120/240 with a Doer cap start motor, and I had to wire it for 120 when I moved, 35 years ago.

 

I want to re-wire for 240, but I can’t remember how, and the diagram is scratched away.

 

I need to unwire it, measure the coils with an ohmmeter, draw the diagram, and determine what goes where.

 

It didn’t occur to me that a 40+ year old motor might have diagrams online, until I read your post.

I seem to recall the strobe balancer we had at the tire shop I worked at 50 years ago could only be plugged in at one outlet and was only used for the balancer.  Very heavy cord.  I suspect it ran on 240 and the strobe may have been 110.  Most of the car and light truck tires were bubble balanced only back then and the strobe brought out only when an on the car balance was needed.  Occasionally semis, school buses would also need balancing and would have to be done on the vehicle.  Those tires took a lot to get them up to speed so I don't think a 110 motor would have had enough.  Cement trucks and logging trucks with the big flotation 22.5s would have to be done in stages because of all the mass it was trying to get moving.  Only a couple of us in the crew did those.

 

My story doesn't help your wiring dilemma.  The motor may have started up on 110 and switched over as it came up to speed and I can't recall if a capacitor was hanging on it either.
