Clarke does your coach have an isolator? I dont have anything like that on mine, I have never really fully understood how this system works, any other input would be appreciated. On the dash is a 3 position switch on off on. The solonoid that connects the two batt cables from either side has one wire that when is energized connects the two together to "merge" the engine side batts with the coach side. So does it matter if the switch is on either position? Does it do the same thing? So with these older coaches with no isolator in order to charge the coach batts with the engine running the merge switch should be in either on position? Please correct me if I am wrong, this is how I understand it works.
