Hi guys just hoping someone can give me advice on isolators. What size should I be looking at? Is 100a enough? And how important is it to have a switch over type for linking the batteries for starting if the main one fails.
Also any suggestions on where I can get a tray for the second batt?
I'm thinking of putting a sidewinder unit under the bonnet and a manual switch in the car to link if needed probably go with a optima yellow top as the second battery.
Cheers
