i have an FIA battery isolator switch with quite a few connections as well as the 2 larger bolt on connections.
my question is how do you connect these properly in order for it to work correctly as ive heard of loads of people who turn there isolators off but the engine keeps running? is there a 'correct' way? cheers

This help you

wiring diagram

yeah thanks for that!
what size cables are needed for each terminal and what does the resistor do in this circuit? cheers
