PMS medication required
My low range indicator does not light but my 4X4 light does when in high or low range. I've checked the switch and bulb and both are good. I tested the plug that connects into the switch and I get a reading of about 12 volts on the one lead but only about 6 volts on the other. I don't know if that's normal or not. Does anyone have circuit info on this? What is the wire color code going into the firewall? Is there any other things on this circuit?
