Hi all, I have read many times about having an isolation switch for the dual battery set up. A couple of questions if someone could answer for me please.
1. I can't see an isolator switch on my set up. What is it, what does it do and how hard is to install one?
2. I have also read that some people charge their second battery over night. Isn't it chaged whilst driving like the starter battery?
Thanks
Paul
You don't have to have an isolation switch altho 95% or more do so that you can stop a load draining both batteries.
They can range from a simple On Off switch like a Cole Hersey, to a solenoid to a smart relay (or VSR) such as Redarc Piranha etc etc
Instrallation varies from easy peasy to medium depending on how techo the switch is and how eleccy savvy you are
Vehicle Alternators are crap at correctly charging a battery.
Vehicle alternators are really crap at correctly charging two batteries.
Most people with dual (or more) batteries will charge their batteries overnight once a month or so with a good quality smart charger (CTEK etc)
This will significantly increase the life of your batteries and for any nah sayers it sure can't hurt

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
