Another Sr20 no crank, no start. Out of ideas!

Here is the situation...

Two days ago I get ready to go to work in the morning, like usual.
I go out to my drive way, jump in my 240 and I crank over the engine a couple times. Btw, the motor is tuned on E85 ethanol, so on cold mornings it's a PITA to start as I have to crank over the engine a couple times, let it rest for about 30 seconds to allow the starter to cool down.
Any ways, I crank it over about 4 times, wait 30seconds, try it again, wait 30seconds, and on the third attempt the engine won't turn over.
It makes a click noise only when I turn the key, which makes me belive the starter or battery.

Later that night when I return from work, I cleaned the battery terminals, check grounds, and brought a jumper. I give it a go, and again no crank.
Well no biggie, I have a spare starter in the garage. I swap that bad boy in, and again no crank....
Lol, at this moment I take the starter out, I bench test both of them and they both work!
I have checked fuses, and they are also good.

Only thing I can think about is the harness for the starter/alternator maybe be not getting enough juice.

Help please, gracias
