coil question
I'm currently changing my 1971 original 350cid engine for a 383cid engine including all ancillary parts such as tuff stuff starter, mallory electronic dist, mallory coil, proform carb, air gap intake, PM alternator, and so on.
Q: There are two wires coming from the fire wall for ignition (one black and one red with cloth sheath) that are soldered together that connected to the "+" side of the old coil. The black wire is getting very hot when the ignition is in the start and run positions. I thought that this wire is somehow related to the wire that I cut at the starter so I cut if away from the black wire that it was soldered to to see if this helped the "hot" black wire situation. It didn't seem to. The black wire reads 12V when it is disconnected from the coil and 9V when connected and the engine running. I read some posts about needing a new ignition wire and a ballast resistor????????

Are you using a ballast resister? The Mallory Ecectronic Distributor I have requires one. Check your instructions. If your Mallory is the same as mine, you could cook the electronics with 12v. What model are you running.

My Mallory Unilite distributor has a Mallory coil with an external ballast resistor on my 77. It is required with this coil. I have since bought a Mallory coil that doesn't need one and I will bolt it in when the original fails. I don't know if a 71 had a resistor "wire" that could be substituted for the Mallory resistor block.
