More Electrical Help ...

Update....pulled main harness out and took voltages at light sw.
Getting closer to one of the problems.
Why does it have connection in run?
And why isn't it turning the starter in run of there is power on the hot side?
Is the ground run to ignition switch or something strang liek that?

The old ignition switch does not have the grd connection on it. But the car is cranking fine now - starting - radio works, now headlights work...as you'd expect, have some 12 volt power to the light switch and the temp gauge is maxing out again...still no movement from the ammeter or gas gauge...but the gas gauge may just be registering low because there is little gas in the tank, so I am going to get gas and see if there is any change...just do not understand the ballast resistor issue...the new starter relay requires a ground wire and S-2 is in a different position, but the car cranks correctly...
