Scotty AI Wiring (Completely Di erent to Scotty V1) for 4WD 5m run to Scotty 12V - 48V
Cable #1 marked Current Sense + is used for sense wire to Alternator. If hard to get to alternator, it can be on the starter battery but control will not be as good. If it is not used Scotty AI will not function. Cable #2 marked Current Sense - is used for power supply to Scotty Touch Display as 5V+ Output. If no display, just leave coiled up and reserved. Cable #18 marked Temperature Probe is used for Temp Sense Positive. Cut the current temperature “ring” o this cable. Connect this to the positive of the new temperature sensor. We use the same temperature sensors Victron Supply with Multiplus inverters. After cutting o the ring, Cable #19 marked Temperature Probe is used for GND (Black) Cable #20 marked “ignition or power” is to be connected to the High Side (48V typically) Cable #11 marked CAN + is CAN hi for connection to CANbus Cable #12 marked CAN - is CAN hi for connection to CANbus Cable #21 marked “Feature In” is to be used to disable charge from a BMS “stop charge” relay. A high signal allows charger. There is an “inverted” selection in the app for reverse condition wiring. Harness Cabling (instructions are for upgrade Scotty to Scotty AI). For new Scotty AI Cable numbers are the same. New labelling on its way but you may have Scotty Ver 1 labelling.
