Need to make sure you see what's been done to the car. 80% chance it has been converted to a 12V battery and neg. ground!

Ah - fond memories. I had a 67 BRG.

I bought this 12V neg. ground converted car for a song. Owner thought it had a cooling system / engine problem because after warming up it would stop running. It had sat for a couple years and he moved and couldn't deal with it anymore.

Turns out the car had an ignition coil hooked up wrong - assuming it was still pos. ground. So after a few minutes the coil would overheat and the car would stop running.

I had a mechanic buddy at the time. He spotted that after a couple rounds of re-creating the symptoms.

So, in summary, the other guys are correct with their assessment, my input is to be checking carefully what's been done and making sure everything matches the conversion or lack thereof.
