Read the big three sticky up above in this forum.
Take that cap out and get a new HUGE high output alternator...I mean massive of your potentially running around 3000 watts its gonna pull some major amps.
Thats well over 400 amps...just a rough estimate...I know it could be more or less.

you cannot run a 16 volt battery in line with a 12 volt system, your looking to smoke something. Look into a higher amp alternator from a reputable company.
Irragi, ohio gen, powermaster are all good places to start looking at over a 200 amp alternator

ALSO KEEP IN MIND THAT YOUR CAP SHOULD BE 1 FARAD FOR EVERY 500 WATTS OF POWER.THIS IS ADDITIONAL OF COURSE TO YOUR H/O ALTERNATOR..
