Hi All : I did it this time 53 ford Golden Jubilee, so proud of getting fifteen years out of my battery, kept trying to get tractor started one more time, gave up, bought new 6 V battery hocked it up nothing, so I ordered new voltage regulator, solenoid , key switch and starter push switch, just changed solenoid and new 200.00 battery, let’s try this first, connected battery positive ground and negative Boom blew off top of battery nice show Ed, fifteen years ago replaced voltage regulator, solenoid, rebuilt starter and generator, and wiring harness, I was going to pull starter get rebuilt, and change voltage regulator, key switch and starter push switch next , use tractor for snow removal and rear dump bucket , light use. Any help is appreciated , one should be smarter after 80 years old !!! THANKS ALL TURMAN
