Yes, drain it into bucket. Then you can filter it through old T-shirt and pour it back in at end. Why are you losing coolant? Fix that problem too.

1) What do you mean "bridge two terminals"? Sorry for the basic question, but I'm lost on the terminology here.
When you unplug connector from thermoswitch, you'll have connector with two metal terminals inside.



Make short jumper wire with bare ends.



Plug it into connector's metal terminals to send current from one across to other.



With key ON, this jumper should activate fan (if it's operational). Also measure for voltage on blue/white terminal of this connector and there should be +12v power if wiring is correct.

2) Do you have a suggestion for getting +12v? I haven't tested some of the rogue wires so I may have a live wire somewhere that was leading to the grip warmers (not good, but can fix that later), but if not is the best bet to go buy another battery?
You can get some test-leads with alligator clips. Then get power directly from battery to test fan.
Or you can also clip to auxiliary power-connectors near front.
