I recieved a new switch. The only marking on it is the next to the top spade marked "RED". I read the switch out with my ohmeter and hooked up the load to the top spade, the source to the middle spade. The accessory works fine but the switch doesn't illuminate and when I ground the bottom spade it blows fuse. I tried all combinations and still no joy on getting the light to work, although the load works fine. Does anyone have a wiring diagram on carling Illuminated toggle swtiches?
