I’ve owned my ’76 since September, and it had what I thought was a marginal battery. For a couple of months the starter would barely turn over, but the motor would always fire up, and I always carried jumper cables figuring I was getting close to needing a new battery. Now it does nothing when you turn the key. No click, nothing, even with jumper cables. I recharged the battery for about 10 hours and put a tester on it which gave a reading of fair. All other electrical components work fine. I tried the old screwdriver trick, using the blade to bridge between the positive and negative terminals on the solenoid, and I get a click, but that’s all. Question: How do I know for sure if it’s the starter that needs replacing? All the wires seem new, intact and tightened down, and the starter looks to be fairly new. I hate to buy a new one if that’s not what’s wrong.
