1949 Ford 8n
Good afternoon all. I have a 1949 Ford 8n 6v. It is turning over slowly, when i test the starter, i have 6.35v on the battery side, and when i activate the starter i only get 4.3v on the starter side. Does anyone have any ideas on this? Thanks for your help.

It could be a bad cell in the battery, check the voltage at the battery terminals when engaging the starter. If it drops, bad cell. If it stays at 6+v, check the connections at the terminals, starter connections, and solenoid, if separate, and ground. Take note of the cable condition as well; if the clamp has lots of corrosion and the plastic jacket has swelled near it, the corrosion has migrated down the cable and is causing lots of resistance.

Check battery connections paying special attention to ground cable where it attaches to tractor frame. Load test battery with a battery tester.
