I have a '69 satellite with 440 and a few options that I don't think would matter in this problem. I have installed my 2nd starter relay and still have to use the screwdriver key to start the car. I get 12 volts from the yellow wire at the relay when I turn key to start the car. Also, read .3 ohms on the wire from the relay to the solenoid. I don't know if that is good or bad, but know it's better than OL reading. I'll also mention that I've been chasing an overcharging problem so I have cleaned and checked continuity on most wires and have made no difference. Any ideas on what to check next will be greatly appreciated. The most I've come up with is to move the jumper wires inside so I don't have to stand outside the car to start it in front of the Chevy guys.
