I have 2 4D batteries in the compartment under the aft starboard settee. Am installing a Link 20 to monitor this house bank and the Group 24 in the forward settee compartment. Trying to find a location for the massive copper shunt and the 3 ground cables that connect to it. No room in the aft settee compartment. Anyone have a Catalina 36 with this configuration with a Link 20? Where did you mount the shunt? Thanks, Brian Giersch
