1968 Z28 starter woes

[firez]

I tried to start my 68 Z today and the starter would not turn engine over. I pulled it out and used jumper cables and on the floor the starter turned. I put it back in the car with all connections cleaned and tightened up. I turned the key and just had a humm under the hood,but the starter was not kicking in yet it works out of the car on my bench. Any ideas from anyone. Thanks

If the starter is turning, but not engaging the flywheel, check the bendix.

The starter is not turning when it is installed on the car. Just turns when it is on my work bench.

Check the connection from the negative battery cable to chassis/engine if you have not already.

I shall do that when I get home Thanks. Its the small things that are hard to find.

I found the problem,it was a new spring ring positive battery cable. The cable going into the positive terminal was loose causing the problem. If I held the cable tight into the spring ring terminal the car would start. Thanks for the help,who would have thought a brand new battery cable .

How do New Car Dealers auto mechanics make money if every thing is new? Find and fix just like you did. Paul

Paul, I am glad you found the problem. I was just before recommending that you start parking facing downhill, which would not have been much fun in the snow.
