ok im about to fit battery to boot
got a bat box, agm battery, cables

plan is to fit the pos from battery through cabin to the starter motor. have 4 other acces wires for thermo fan etc going to pos on battery (all though relays) and the fusible link.
was going to run these straight off the starter too.

my question is should i run a fuse/curcit breaker on the power to the starter? if so what amp?

was thiunking of running a keyed isolator switch too either in boot, cabin or even where stock battery tray is too. so if i go:

battery - curcuit breaker, isolator switch then starter would that work

or as im running fusible link stiff could i just go batt, starter and all off that?

could even go batt, isolator swich starter, and runn all the wires off isolator switch, before starter... that would include fusible link.

spoken to a few member who go battery, isolator starter , and run all their stuff off starter post.

cheers
