Hey, since you cut the wires to your key, your TSS and the kill switch on the right side of the handlebar are the only ways you have left to shut it off. They both use the same circuit, and hence you're unplugging them both, so be aware that you'll need to reconnect the plug to shut it off! If you can't figure out which connector it is, just unplug everything that goes the the right side of the handlebars. That'll do it. 
And you need to check the belt deflection. Mine had a very similar bog, and that's what it ended up being as far as I've been able to tell. You should have the top of the belt riding 2-3mm ABOVE the tops of the secondary sheaves when stopped. (I forget the actual deflection measurement...) You add or subtract some spacers as necessary to get it to ride there. My sled had an unused spacer in the tool kit, and I used it to get the belt to ride high enough. (Worn belt evidently requires more spacers IIRC)
Good luck!
