Overview
This is a hands-on electrical diagnostic for six-volt Farmall 6 tractors, not a walkaround. Tom explains why slow-cranking or dead starters usually trace to undersized cables, corroded connections, or worn switches rather than the battery itself, then physically replaces cables, crimps and heat-shrinks terminals, and cleans/tests a light switch with a multimeter. Useful for owners troubleshooting six-volt starting issues who want real wiring detail rather than a case-for-12-volt-conversion argument.
