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. 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.
