[QUOTE="condor22, post: 300674, member: 1932"] Bundy, 1. Re the input 50A fuse - place it as near to the start battery as possible. Also consider using a self reset circuit breaker instead of a fuse and run a twin cable to the rear one for + and one for - that way chassis earth which with all the plastic and sealers used in vehicles today is a better connection. The Anderson in the back end is fine for disconnect, get one of the rubber weather covers for the Anderson to prevent accidental shorting. 2. Re connection - Anderson on the input cable from the main battery, then Anderson on the input of the IDC25, then Anderson the output of the IDC25 and finally Anderson a lead to the AGM. Using twin core cable the whole way and Anderson plugs, everything is removable. Don't forget that by connecting directly to the main battery you are relying on any low voltage settings within the IDC25 to protect the main battery from being discharged to low. Even though I have a Redarc BCDC that can do this, I use a 70A solenoid under the hood to positively isolate the main when engine off. [/QUOTE]
