Bill: I own a 2001 Safari Zanzibar and have replaced the original alternator with a single wire 180 amp Delco. If you understand the purpose of the isolator it really is not necessary. The isolator is used to direct alt charge to either house or coach batteries as needed. The inverter has a battery charged built in to keep house batteries charged. We have been on the road full time for three years and have not had a problem without the isolator. You just need to hook battery wire from alternator to coach side of bus bar to keep chassis batteries charged.
