The starter I bought is supposed to be for a '68 Fairlane, I'm using the same tranny (C4) original to the car, and bought a new 50 oz 154 tooth or 157 can't remember now but it has the same number of teeth as the old 28 oz flywheel.
I'm hoping that maybe the teeth just need to break in, they seem to work fine together as long as you don't hit it-let off-then immediately hit it again, that locks them up every time. Turn the motor over by hand just a little and everything's fine again.

The ballast resistor gets warm/hot to the touch if you leave the key on but engine not running. I unplugged the wires at the ballast and I've got 12 volts on the side going to the key switch, and just a couple volts on the side going to the coil??? I unplugged the wires at the coil and the neg./tach side is showing a small amount of voltage which is coming from the control module. I'm using a Duraspark module with the blue grommet and a TFI coil made by MSD. I'm sure it's wired up right, and the problem goes away after the car is started.

Can anyone unplug their coil and see if they read pos. voltage coming from the neg./tach side of the coil, I'm getting a small reading here and I'm sure thats what is making my ballast get hot, power coming from both sides. Just thinking I may have a defective control module.
