Hi All, looking for advice please. Ive lost a 12v supply to my fuel shutoff valve on the engine, kubota v1505. i have the 12v when ignition switch is on but the power for the second wire which i assume may come directly from the ( i assume) starter motor has failed. Does anyone have a wiring diagram / or can confirm where the 12v is supplied from would be great. The solenoid will work if a temporary secondary12v is supplied. Many thanks for any help.

    Depending on how it’s set up. They usually use either a timer/relay, which could be anywhere and that could be bad, or they run directly from the starter bendix post for the initial pull in operation, for the fuel shutoff solenoid. There could and should be an inline fuse for that.
