Have a 10 inch Craftsman radial arm saw since 1975 and suddenly it has
developed a dead short somewhere, disassembled the motor and everything
looks good, it has a capacitor about the size of a C flash light battery is
there a way to check to see if it's any good? Thanks
Get the numbers off the capacitor and check an electrical supply house for
another. Replace. Probable cost under 10 bucks.

Hopefully it's just a start capacitor. Should be readily available at any
electric motor shop. I buy such things at my local air conditioner
warehouse where the local installers buy from.
Almost a decade ago, I bought a 1980 era Craftsman RAS used for $25. The
motor was dead, but the rest was in good shape. Packed full of sawdust, the
coils eventually cooked. I took it to several shops to get it rewound.
They said they won't touch a universal type motor. I paid $255 for a
replacement motor from Sears. My bargain saw wasn't a bargain anymore.
Still, I now have a old era saw with the better guides with a new motor for
about half of what a new one costs. To make the deal sweeter, Emerson
Electric had a recall on this model. They sent me a new blade guard and a
new wooden tabletop for free. Now my saw looks and performs like new.
Maybe you'll get lucky.
I had the same problem with my circa 1978 Craftsman RAS. It turned out
the problem was with the overload protector. If you were tripping the
automatic overload prior to the motor going dead, you might want to
check that out.
Also, in case you can't (or don't want) to fix this, you can use
Emerson's RAS recall. This saw is too old to be fitted with the
replacement guard, but I think they'll pay you $100 for the old motor.
At least, you could use the $100 toward a new motor, if necessary.
