TomB Posted January 14, 2021 Share Posted January 14, 2021 Hi,For a number of years Ive had a feature of my FIA switch that it doesn’t kill the light and dash lights. It kills everything else, but not the lights. I’ve got my scuttle off at the moment so I thought I’d try and investigate why.The car is an early 1996 K series, before the comprehensive changes to chassis and loom post 1996. As such, it has an older Ford chassis wiring, but with the injection engine loom. My Multimeter shows battery power is reaching the light switch (brown & blue wire) when the FIA switch is off and the wiring diagram suggests this is from a common connection on the ignition barrel with the brown wire that eventually ends up at the starter solenoid. As such at the solenoid, it’s sharing a big red cable.On Sevens with Ford chassis wiring, how do I make sure the FIA kills all electrics? Below are the diagrams I’m working with. Below, the red is from the battery, green is to the ignition and blue is to the light switch. The cut off key doesn’t appear to cut thes connections, as neither go to the small connection on the switch. Is thish just something I have to accept, or is there anything I can do.
