Dual 510 -- power loss?

Hi folks. This is my first post, so hope it's in the right place.

I have a Dual 510 turntable that all of a sudden won't turn on/spin when lifting the control arm. (Full disclaimer: I know basically zero about turntable repair.)

Anyway, I popped the plate and cover off to investigate. I used a multi-meter to test the SM840 motor and it was 0.5 Ohm, which seems acceptable. The control arm mechanism appears to be OK. Could it be the power cord or wiring? The pulley seems fairly loose, and I've ordered a new one, but it seems like that wouldn't prevent the record player to power up when moving the control arm. Photo below. Any advice would be appreciated for this noob. Thanks!

In investigating a bit further, I removed the switch housing and it looks like a badly blown fuse. Can I just replace the fuse, or is it best to get the entire switch assembly with fuse?

What fuse?
Even without your picture, I can tell you NO FUSE.
Did you by any chance post the same on Dual Turntable FB OWNER's page?
 
Isn't the top part a fuse in a resistor? If not, what else could it be? No, I've only posted in this forum. Do you recommend the FB one too?
 
We do have a Dual-only site over there, but the guys here know just as much.
Your 2nd pic did not come out.
The part is a capacitor. Charred ir not, ut shiuld not prevent the motor from spinning.
Paur the motor wires as required for USA mains are you here?) and plug in.
Could be the switch contacts.
 
Did this pic turn out better?

FYI, when I closed the circuit on this capacitor with my voltage tester, the motor would run a little.

I think that you simply nudged the connector posts a bit.
Wow, Southern-fried capacitor.
Even if that cap shorted out, this should not be.
Assuming that the motor is unscathed, it is a good bet that the switch is toast. Earlier switches were bakelite. Yours looks like plastic.
 
Hmmmm, interesting, and Southern-fried no doubt. This turn table has moved West to East and back West the past 4 years, so maybe some extra jostling. So just get an entirely new capacitor, even if it's plastic?
