Low Voltage to the coil

What kind of ignition you running? If you are running a Mopar ECU you do not normally want to bypass the resistor on the street

It seems to be a mixed bag (depending on coil type) for those like me running a GM HEI module. I checked mine for heat carefully over some hot day's running, and it seems to do fine.

Other systems, MSD, etc, vary. Follow their destructions.

AND if you are having a voltage drop problem (poor connection) bypassing the ballast wont' help
