HI:
I have a 1969 Mustang, 390, GT. A few weeks back the voltage regulator blew up, and I tired to drive home and the car finally stopped as the battery was fully dead. I replaced the voltage regulator, and charged up the battery. Now, sometimes, the starter barely turns and I get a VERY loud "knock" from the starter area. This is usually after driving a long distance and stopping the engine for a few minutes. I had the battery tested and they said it was good. I have a header close to the starter which I realize can heat up the copper coils in the starter making it harder for the starter to crank. The starter is a high torque starter, and the battery is basically a cheap one. Should I replace my battery with a 800 CCA battery, will this stop the horrible loud knock I sometime hear from the starter? I have wrapped the header with lava tape in an effort to keep the starter cool. What is making the very loud knock??
Thanks,
Mark
