I haven't actually installed it yet - but i have bought:
-1 120amp simple battery isolator [
]Canadian Tire
-1 AC Delco starting battery maintenance free
-1 AC Delco deep cycle/marine/RV battery maintenance free
-a bunch of 10mm cabling
-upgraded to a 100amp alternator
i'll be installing it all in the next couple of weeks for my expedition style build in my 81 FJ45LV...the starting battery should be completely isolated [hence 'isolator'] from the deep cycle battery - pretty much eliminating the chance of running down the starting battery - leaving the deep cycle in charge of keeping the beers cold, the tunes flowing and the extra lights shining...
if anyone sees any serious issues with this agenda, do please be a dear and let me know....
