0 power after going from 40A boost to 200A boost attempting to cold start.

Video explains it all. Suggestions? This weekend I'm going to head back and probe for voltages. Didn't have the tools on me at the time.

Main fuse at battery blown

Also
You should have a battery hooked up in normal location when trying to jump start .

Should yes, but I didn't have one that fit. None of the fuses are blown in either box, or the fuse on the battery terminal.

Has to be a fuse...

even if you completely toasted the ECU you would still get lights.

So , do you have a good battery on it yet ? Any sign of life when you connect that ?

Do you have a voltmeter ?

I was going to try to probe for voltage in the fuse boxes this weekend with a multi-meter, but unfortunately have gotten caught up with work. No good battery yet, trying to get a warranty claim on the one that was in the Rx8, but after playing with a few different things yesterday with the car I could not get any sort of power, even though the connected battery was charged to almost 12v

Get a decent battery connected to it properly then use your voltmeter to check where you do and don't have power . Starting from before and after the main fuse after the battery and then over to the fuse box . If you have power there , test voltage with a probe on either side of each fuse .

Thats the plan! I'm currently fighting with a parts store to get the warranty claim on my "deep cycle" AGM battery... Paid $250 for a battery with a 5 year replacement warranty, they better gimme another one...
If I still don't have power with a new battery connected, I should probably start probing the wire harness right?

Doubtfull it is the harness ............. that's why you have fuses . Just work your way away from the battery logically and the problem will reveal itself .

Be sure your ground wire is secure.

ALL FUSES ARE GOOD. I'm heading back tomorrow morning early to start probing for power through the fuse boxes and see where I have and don't have power. I got caught up with work over the weekend.

edit- got the warranty processed on the battery... Won't have another one till the 11'th, so I will have to wait till the 15'th Will update then.
