Hey guys, looking into installing a second battery here pretty soon. Was looking at buying a battery switch wanting to see what you guys run. I have read a little about them and want to make sure I connect everything right, I've read that if you get the wrong type or have both batteries turned on for ex 1+2 it can cause damage to the alternator. Looking for recommendations on the better switches to buy and also install advice. Im running a 03 Launch SSV with indmar GM small block EFI. Thanks in advance, Matt.
