What's wrong with my VPI motor?

Those owning the VPI TNT (or Aries, I guess, as well):

Have any of you tried different types of belt?

Thank you for your consideration.

At least on the original SAMA motor, removing the bottom cover plate, reveals that all wiring connections, including 2 capacitors, are WIRE NUTTED. (I challenge anyone to name another audio product using wire nuts.) I immediately soldered/heat shrank these, and ran Ven Haus wire to the switch (another price-point jewel)and hardwired a Ven Haus cable.

Point being, at least *look at the wiring connections; if it's (still) wire-nutted, swapping a new cap is, well, like quite easy.

Wire nuts?! OMG... Shasta, you've got me ROTFL.

So that's what SAMA stands for: Saving Any Monies Available?

actually, wire nuts would be more expensive than soldering.
