So my 72 is not starting at all. It doesn't turn over but clicks like the starter went out. I have tested the starter and alternator. Picked up a new battery and replaced the external voltage regulator. The problem is still the same. I drive it all the time so it's not like it has been sitting. Any suggestions on things to check. Any help is appreciated. Thanks.
Ok, so I just went up and had the brand new battery checked and it was dead with a bad cell. They gave me a new one and I took the car to have a complete charging system check and everything checked out fine. So I think it may have been the voltage regulator that I replaced. We will see tomorrow after it sits all night.
