I just finished up a 4 speed to th350 conversion in my 57 and thought I had wired everything back correctly until I just tried to start it back up.
It turns over and runs great until I release the key to run, at which point the car stops running. I have been running an MSD Ready to run distributor with MSD Blaster coil with no problems at all. The stock ballast resister was eliminated when when this system was installed. The only intentional change I made was the addition of a reverse light/nuetral safety switch on the steering column.
Could improper alignment of this switch be the problem? I have backtracked all of my wiring and everything seems to be as it was. I also removed and did not replace an old tach and it's wiring.
Anything that anybody can think of that I might have missed?
Thank you very much,
MikeH

Check for 12 volts on the + coil terminal with the key in run position. If no voltage, check the wire on the "ign" terminal, that it didn't come loose.
How did you rewire when the ballast was removed? If you joined the ballast resistor wires, check that connection.
The coil gets voltage from the starter R terminal, when the key is in "start" and from the ignition switch in the run/on position.

Thanks Don,
There was no voltage yesterday between the coil posts with the key in the run position. I’ll re-check connections when I get home later today

Check the + post to ground, not between them.

Put the red connector of the volt meter on the + post of the coil, and the black connector to ground, with the ignition switch in the run position.

Checked connection as instructed. No voltage. Will check connections tomorrow. Thanks for everyone’s help with this. Something may have loosened up although I gave all a good look during the installation. Will keep all posted.

Many thanks to all. As Don suggested the connection that I made when eliminating the ballast resister had loosened up during the changeover.
Car started fine and runs great. Now on to adjusting my shift linkage! If I need help there will post up in modified. You guys are great!
