I have replaced everything in the starting line. New super heavy duty wires, new battery, changed the starter floor switch, and even put on one of those new 6 volt starter. But the car still gives me problems at times like it has a low battery. I just don't know what else to do. Have any of you had problems with those new reproduction starters, floor switches or 6 volt battery. I have also put on extra grounds to make sure that isn't the problem. Sometimes it will spin ove like a new, and other times it just grunts. Thank, Jerry 1931 Flamingo 07-16-2022 @ 10:32 AM reply profile send p.m. Member Posts: 379 Joined: Nov 2019 Just guessing here but how about the contacts in the ignition switch??

Both the starter and the oil pan should be clear of paint in this area. also the starter motor has a couple of sections that the joints should also be clear of paint. The two long bolts that mount the starter should not have painted threads and the hex heads should have star washers between the rear end plate and the hex head. voced 07-17-2022 @ 4:45 AM reply profile send p.m. Member Posts: 86 Joined: Oct 2009 It starts great if it turns over correctly. My other Flathead Fords don't have this problem, but this one has gave me trouble and I have tried everything.

Have you cleaned and tightened all of the electrical connections in the starting system including all of the ground paths? Are there any parasitic drains on your battery when the engine is turned off and not running? Once you have done all of these external checks and eliminated any obvious concerns, if the problem still persists, you will have to look inside each component of the system to locate and repair the cause of the problem. Your battery voltage may not be sufficient to crank the engine at the required speed when your problem presents itself. Check to make sure your generator is putting out sufficient voltage to keep the battery fully charged. Does the slow cranking speed only occur after the headlights have been used? If so, you will have to run the engine long and fast enough with the lights off to adequately recharge the battery for the next start. marko39 07-18-2022 @ 6:00 AM reply profile send p.m. Member Posts: 40 Joined: Sep 2016 Check voltage at starter when this is occurring. 37RAGTOPMAN 07-18-2022 @ 7:15 AM reply profile send p.m. Senior Posts: 1939 Joined: Oct 2009 was wondering if you have a battery disconnect switch ? I had the same problem, and that switch was the problem, now I use a 1/2 inch wrench ALSO do you have a GOOD GROUND going to engine to chassis ? a corroded ground connetion or loose, or to light a cable hope this helps 37Ragtopman voced 07-19-2022 @ 5:38 AM reply profile send p.m. Member Posts: 86 Joined: Oct 2009 I have a cutout switch, but bypassed it and didn't make a difference. Also ran several more clean new heavy grounds. This problem has pulled my hair out. It is worse when hot. I did clean the paint under starter and put star washers on. Thanks again for your thoughts. Jerry 37RAGTOPMAN 07-19-2022 @ 6:46 AM reply profile send p.m. Senior Posts: 1939 Joined: Oct 2009 I would swap out the starter, for a original maybe the comutator is swelling when HOT and rubbing against the fields, this is A long shot, I have used CERTIFIED AUTO ELECTRIC in OHIO, for rebuilding starters and GENERATORS I am not a fan of this new repro parts that some vendors are selling, my 2 cents 37Ragtopman , Maine ALSO , when engine is HOT, TRY turning the engine over by hand, you could use the hand crank try it cold and hot, was the engine rebuilt ? voced 07-20-2022 @ 5:28 PM reply profile send p.m. Member Posts: 86 Joined: Oct 2009 I have considered rebuilding the original starter, but it did this before I put on the repo starter. However, I think this is another thing to try. I would guess that the windings on the old starter are better than the new repo ones.
