Ballast Bypass

You dont want to run the car long with the ballast jumped as it can burn out the coil and ecu. Its not a 6 volt coil on the cars. The reason for the ballast resitor is to keep the current flow (amps) to a certain level so the coil wont overheat. All manufactors ran a type of resistor in the ign circuit when they used points. And they all bypassed the resistor on cranking becuse when the started draws 200 amps it pulls the battery volts down to around 10 to 11 depending on temps outside which will drop the coil volts and amps so they bypas the resistor on cranking and give the coil about 10 volts instead of about 7 that it normally runs with when driving. Ford and GM also used a resitor up into the early 70's when they used points also but they had a resistor wire built into the wire harness. And they both bypassed them by a small finger contact in the starter solenoid that supplied 12 volts to the coil while cranking. Mopar bypassed its resistor with the ign switch. Ron
