Quick question about the overdrive relay. I can't get my relay to actually operate without external power. Schematics say that power should come from the ACC on Ignition. I'm only getting 6 volts. When I bypass and run a wire from batter to relay it works and my overdrive is alive again. Thoughts? First instanct is that I have a bad ignition switch. This switch DOES crank the truck very well. Thanks for the posts.
