Electrical Problem-71 convertible
I have been rebuilding a 1971 convertible for the past five years. Last week I tried to start the motor and I had no ignition voltage (nothing happens when the switch is turned on), however when I tried to start it the turned over and the engine started. I had to turn it off immediately because the starter was engaged. I changed the ignition switch and still have the same condition. Any suggestions?

Have you checked to see if there is power on the positive side of the coil when the key is in the run position? Should be about 8 - 10 volts.
Also when the key is turned to the start position it supplies full voltage to the coil. This is done with a sepeate wire that runs from the starter solenoid to the coil. This is why the engine would start when its turned over.
If the solenoid is not disengaging when the key is returned back to the run position this will still supply power to the coil.
You may want to check that you have no issues with the starter solenoid.
Also have you replaced or done any work on the harness during the rebuild.

Thanks for the response and sending me in the right direction. I changed the starter solenoid and noted that I had the yellow and purple wire reversed. Wired correctly and she fired right up. When I put the wiring harness on I had just gone by wire length rather than looking at the schematic.
