Just blew the ignition module inside my Mallory distributor. When I installed a new module I read the enclosed instruction sheet that stated "Failure to use a resistor will result in the eventual destruction of the module".
I have a resistor, but it has been bypassed by someone working on the engine.

Should I move the red wire from the coil and reconnect it to run the current through the resistor?
 
Im not a pro on ignitions but I think it depends on your coil that you are using. if your coil is internally resisted then you don't need the ballast resistor and vice versa.

Also if you leave your ignition on for a long time without it running you can burn up a module that way.
