Mr. B, I read your reply about 6 and 12 volt batteries. If I under stood correctly, both cables from the battery should end up on the starter. one hot one ground.
Meaning ground cable to starter from battery , being better than just grounding to a shinny spot on the tractor, under a nut and bolt.?
Thanks in advance.
Most machines depend on the iron of the tractor to complete the circuit. In old machines some of those points where the electron's current path depend on metal to metal contact, paint, rust, grease, & dirt interfere with the current flow.
If the starter does the same job in 6 or 12 volts we are talking watts (the unit of measurement of total power)
If voltage (think of it as torque) is reduced, amperage (think of it as flow rate)must increase.
If you buy cables made for a 12 volt system they will be smaller gauge wire. A 12 volt starter might draw 200 amps to start, a 6 volt might draw 400.
Good, heavy cables, two good identical batteries wired in parallel, two solenoid relays, and "ground" run from battery to the starter frame will improve starter function, and reduce amperage needed to crank.
People convert to 12 volt systems, when cleaning up ALL the connections, heavier cables, directly run would solve the problem.
