WARN isolator great for Toyota FJ Cruiser Nov 10, 2011
By Dennis Alva Installed this isolator in my FJ Cruiser several months ago for a second Optima Yellow Top battery. It is compatible with the Denso alternator and it works great. Both batteries stay 100% charged and the FJ power system is affected in no way. The instructions were reasonably easy to follow and it worked from the first start.

Dual battery protector Oct 06, 2011
By R. Lahr Using this protector system (for power systems with two batteries) prevents accidental discharge of the primary battery. You could make it yourself out of individual parts, but it would cost more than the Amazon price to do it that way.
