My AWD is not working ,the front hub coils are not magnetizing correctly.
I need to figure out how to bypass, or figure out where the "diode" is that allows current to pass in only one direction to my hub coils.(1999 SP 500) My hub coils have 12 volts and 25 ohms unplugged. (I borrowed electric from my brother's SP and my hubs will lock perfectly.) Somewhere there is a safety wire or switch that's not letting my coils create enough magnetism to engage my hubs. This switch\diode is keeping current from circulating through the hub coils. I have a tiny amount of magnetism using my SP electrical system but soon as I jump electric from another SP hubs will lock. Also AWD light doesn't light up but used to. The bulb is good. I have voltage at the AWD switch and have jumped across for testing. It must be a sensor problem, but I can't figure out exactly how to narrow this problem down. All helpful advice is appreciated. Thanx Polcat
