New to the Forum. I have a 1970 FORD XL. 429 CU. IN. Auto. Trans, Convertible.When I drive 20-30 miles ,turn off engine and try to restart ,starter drags,or will do nothing.New starter,heat shield on starter ,less than 10,000 miles on rebuit engine.Has not over heated.Any ideas.

 

Welcome to the site..

Charging system has been checked? After some extended driving and a out of spec system would/could drain the battery reserve..

 

New alt. ,volt reg,coil.,batt.,Amp ga. shows steady when running.

 

I think Hayapower brought up a good point. The way those amp meters were wired , if the charging system put out 5amps it will show charging but the vehicle could be pulling more than 5 and the battery could get run down. If the battery cables are so, so, it could start ok when cold , but when hot they could have some hi resistance and the charging system thinks the battery is fully charged when it really is not. It would be a good idea to check just what the alt/gen is putting out. check that at the alt and battery ! Last , you could have a defective starter !

 

Thank you for the input.Will recheck everything again.

 

On a restart attempt,

If jumped with a set of 'good quality', heavy gauge cables to a hot donor vehicle, does the engine spin over at a normal cranking rate?

 

Yes even hot it will start when jumped.If not jumped you have to wait for motor to cool down before it will start.
