    Yes you are correct. That fuse also powers the Kysor stuff like oil and water shut down. If one of those wires is grounded out it blows. Also powers the reverse lights so if you replace fuse make sure it doesn’t pop when you put it in retreat
     
    Oxbow Thanks this.

    Well I #### sure didn't remember it, and I won't remember it when I need to, I just spent a half an hour looking at that schematic.

    I like that "put it in retreat" !

    D3D6F072-C0DA-4B93-9C2E-37AFE35B27E6.jpeg New electric sending unit and new gauge. Sending unit is installed and as recommended I didn’t thread tape the bottom threads. Ok, got the gauge and there’s 3 terminals and the obvious ground terminal, S and I. “S” is sending and “I” is ignition/power?
     
    Oxbow Thanks this.

    Interesting use of the passenger side box area. Hydraulic tank and boot box with step?
