When I bought my twin fan setup years ago. I really didn't understand the load/ Current draw of twin fans. I too just bought a "Painless Electrics ". Wiring kit.
have had 3 circuit breakers fail. Circuit breakers just don't work with underhood temps and fan startup surges. Use a fuse. The relay they supply is not enough for twin fans. Melted the connections twice and changed 4 relays. Melted wiring connections at the fans.
the painless kit is just not up to twin fans.
you need a proper fuse, not a breaker. You need heavier wire. And you definitely need a properly setup charging system.
if you haven't gone to Mad Electrical's web site and read there tech pages on Alternators yet. Please do so.

All, Thank you for the help. I think that I am going to have to just go with the mechanical fan until I can buy a better more robust wiring kit. I may just take the painless kit apart and replace the wires a couple steps bigger for each. But regardless, it seems that I was perhaps saved from some unnecessary headaches
