Hi All,

New to the forum but not new to Chryslers. I picked up a 1964 300 last weekend, which had the ignition tampered with. I got a replacement ignition switch, but when i tried to start the car nothing happened. No lights, nothing. I tried to jump the car, nothing. Took the battery to Autozone they said it was shorted out. Bought another battery. Nothing. No lights, no power at all.
Checked the cables and roughed them up with sandpaper. Nothing. Tested the battery and it is charged.
The replacement ignition switch I got, which is the same switch EVERYWHERE I look, has 6 prongs on it....ACC, IGN1, IGN2, GRND, BATT, and ST. The ignition plug on the Chrysler has 5 prongs. When i plug it in, the GRND prong has nowhere to go and just sits outside of the plug.
I have looked high and low online and I cannot find a 5-prong ignition switch. Am I missing something here? Am I using the wrong switch? Or could it be something totally unrelated to the igntion switch (a fuse or something?) Is there a master fuse on these cars? I have the wiring diagram and it shows only 5 prongs on the ignition switch.

Thanks in advance.

Keith
