[GreenKeys] M28 motor won't start

[Duncan Brown]

Thanks to everyone who replied!!

I'll have to pull the motor when I am at the Museum next Tuesday. Have 
to find my right angle screw driver as this M28 has the three-speed gear 
shift and it covers up the motor wiring screw terminals. (or maybe would 
be easier to just remove the typing unit first!)

I'll check the relay contacts first.  I noticed in Bul 295 that some 
units had a spark suppressor across the contacts and other units used a 
triac to do the start coil switching, so arcing of the relay contacts 
apparently was a problem.

Tom - if the relay is the problem & I can't clean it up , I'll take you 
up on your offer. THANKS!

Ed - I'm not in a big hurry for one.  This M28 is the only one on 
display at the Museum right now (though there are others in storage), 
but this is the first winter that the Museum has been open, so not a lot 
of visitors coming through. (Also not as much tourist traffic in upstate 
New York at his time of year!)

If I need a new cap & Ed doesn't have one I'll order one from Grainger 
or SurplusTraders.  I'm not against tyraping a larger capacitor to the 
motor chassis if I have to!

Steve - thanks for the info on the FSC # & SurplusTraders.  I didn't 
think there would be any of the original caps left around, so I didn't 
bother to search for the TT part #.

Thanks again & Have fun,

Duncan
