Mk VII Shopsmith Switch

Hi
My Shopsmith all of a sudden wouldn't turn on. I checked the line in to the
switch and have 110V at L1 & L2. No voltage out at the other L1 & L2, but
there might not supposed to be. From there I don't know where to check next.
The wiring diagram is too complicated for me. I am trying to find out if it is
the switch, capacitor, relay or motor that has gone bad. The diagram is at

Appreciate any help. Thanks.

I don't have a shopsmith, so I don't *know*, but my
bet is that you should see 120 v across L1 and L2 on
both sides of the switch when the switch is turned on.

If it was mine, I would disconnect the plug, then install
jumpers to connect L1 to L1 and L2 to L2. Next, turn the
switch on. Finally, plug it in. If it runs, that demonstrates
that the switch should connect L1-L1 and L2-L2 - and the
switch is bad.

And before you do this, make damn sure your circuit-breakers are
working and perhaps install a GFCI while you're about it.
