I love reading about modifications. But please, tell us why do you want all that electrical power?I have installed second battery (parallel dual) with the factory cables.
Also installed a 220A alternator. Stock setup is a 145/160 amp alternator, with a 175A fuse.
Sounds like I'm supposed to add a larger fuse (250A?) but am worried the battery and alternator cables maybe too small?
What if I wire a SECOND CABLE from the alternator to AUX battery with ANOTHER 175A fuse?
The batteries (+) would then be connected through both the starter and alternator cables.
Alternator could output full power if needed going through two 175A fuses.
I know many upgrade the battery cables, but with two batteries/cables, I'd prefer to leave it stock if one or two extra cables can achieve the same thing. (I like the stock battery terminals)
Or will this create radio noise or other problems, or just not work like I am thinking?
