check your three yellow wire connection on the same side as your r/r. thats the stator. that goes to the three yellows coming off your r/r. they could be fucked as well...other than that, dont know what to tell you, except pictures are greatly appreciated.
....... Here's one of my '86 melt-downs, a classic i guess........ AmaZING but true, that mess was still charging but soon to fail.
Many people on here (including myself) throw the troublesome plugs away opting for soldering the wires together or twisting the wires together and using some 30amp screw connectors.
Dude - first step - battery good? - You said no lights, no power. -- The r/r connector isnt gonna fix that. -- -But if you do want to do the connector fix, look in the failures thread for good suggestions.
