Is ignition stock? You have a four prong double resistor? Which is burning out top or bottom?

I have a two prong and the whole things is burning up (i was told by advanced auto that the resister was for the ignition had to take the old one in to ask because I didnt know and thats what they told me it was but the location is right in front of of the driver inside the engine compartment

That is the ignition resistor it drops voltage to coil to @ 8V to keep points from burning up. Is system stock? Have you gone with diffenent coil? Electronic dist?

O.K. Have you had car very long? Or did problem start up soon after purchace? Do you have a volt meter? If yes measure voltage to Old School name Ballest resistor in and out. Look at coil does it say ues with external resistor on it? Can you pop dist cap and visually describe what tou see?

With new ballast how long will it run? Does it run well?

O.K. There is a direct short in circuit to coil. On coli there is a Neg terminal --- and a positive terminal +. Check wire to positive side is insulation frayed? Remove wire with new ballast try and start if no burning of ballast the coil is faulty internal short.
