Interesting.. new development.

With key off:
12.5----12.5 00.0----00.0
12.5----12.5 00.0----00.0
00.0----00.0 00.0----00.0
00.0----00.0 00.0----00.0

With key on (initially):
12.5----12.5 0.01----0.01
12.5----12.5 00.0----00.0
0.01----0.01 00.0----00.0
0.01----0.01 00.0----00.0

The ones I marked as 0.01 I happened to notice just barely flicker off 0 for a second as I was originally testing. I went back to them after writing down my findings to test with a lower voltage setting (more decimal places) and in the middle of this, they all (the ones marked 0.01 above) jumped to about 10.5V. At this point turning the key cranks the engine. However, after a couple tries it goes back into the "dead" state, but if I let it sit with the key on again, it eventually comes back.

Is this the circuit breaker maybe not liking the 30-40 degree weather we've been having recently?

Also tested the lights. They never come on, and if I flip the switch (even just the first notch for running lights) then the 0.01 screws all read 0.000 and never appears to fix itself as it does with the lights off and the key on. So that seems pretty suspicious.
