I have a 2005 Moomba Mobius LSV. I want to hook up a second battery with an Isolator.

Has anyone attemped this?

Is there an enticer wire from the alternator to the battery, if not do I need to wire one in and where do I connect it to the alternator?

My Biggest concern is the big red cable coming from/going to the starter (where it gets hooked up to) and what I need to do regarding hooking it up to the alternator. Running a seperate wire to it etc?

Pros and cons of such set-up?
