I am chasing out my electrical gremlins and now am stumped on the turn signals, the car is 70 roadrunner. I have no signals and want to know where the power to the switch comes from. The steering wheels off and I have a new switch, tried it and does not work. I put a meter on the contacts and have no power. I am assuming power should be here on the contacts and the switch bridges the contacts. So I think I am not getting power to here. So it is bot a switch but the power source, the fuses look a intact and the schematic looks like the power comes thru the switch. The car turns over over and flashers work. Any ideas or leads to help me?

Thanks
