ok i want to get a Perko swicth for my boat as i finally decided i need two batterys and want to hook them up correctly .
so the Perko swich has like 4 models which one is best? also while im ordering what else d i need with iut to get it and the two batterys hooked up correctly?
finally i am loking at boat hook up with one engine and two batterys install. it appears i need to put a negative ground thats running to single battery and simply connect it from that one to the 2nd with another winre, then take a positive from each to the perko swicth to 1 and 2 , and finally a separate wire from starter to common on perko swich?
is that all there is to it? also on the starter common how is that ran?
I have a 2000 supra launch direct drive and as of now a single car battery and one deep cycle marine battery i just purchased.
so can i get some help?
thanks in advance
