    66 Mustang Starting Problems…

    My ‘66 seems to be having battery issues or something. It turns over very slowly and does not start. The battery shows as 13.5V. If I jump it, it starts up fine and I can even turn it off and restart then. But if i let it sit for an hour or so, or maybe 30 minutes, it won’t start again. What can I do to fix this?

    Have your battery checked at your local parts shop. Also, do you have headers? Its possible that the headers are heating up your starter and causing some failure. You need either some heat protection for the starter, a new starter, or both. But first check the battery!
