CAT 308e2 Wiring Issue

NauticaEE ยท 2026-03-28 16:12

I have a 2018 308 that has no power when ignition is turned on. ECU has an orange LED on and hour meter turns on. Battery voltage is good and if I jump power to one of the main relays next to the battery (purple wire) I can start it by jumping the engine starter but still zero key control. I was wondering if maybe someone had some wiring diagram for the machine ECU and the ignition circuit so I can start chasing wires. All fuses and relays test good. Thanks a lot. Serial number is FJX12200
