1950 Ford 8N 12 volt conversion

Maxie Allen I recently did some web research on ford 8n 12 volt negative ground conversion. After studying some information and wiring diagrams I felt confident and decided to attempt rewiring my tractor. I followed the recommended wiring diagrams to a T using all the recommended wire gauges and alternator. My tractor cranked in the opposite direction ( counter clockwise ) and ruined my starter. Can someone give me some advise on what to do next.
jwm If the starter turned backward it was because it was wired backward. The + positive post of the battery must connect to the starter selenoid. From there it goes directly to the starter. I think you need to recheck these things. James
jon i am converting a 6v+ to a 12v-. do i need to change my starter solenoid to a - actuated two pole instead of the single pole + actuated system it has with the -6v system?
eli need a wireing diagram for a ford 8n 1950. i put a new steering on it and the wireing does not match.
fjb I bought an 8n tractor that was already converted to a 12 volt neg grnd system However the genuis decided to bypass the safety button which I found out the hard way can cause the tractor to start in gear.
I bought the start button however I need help with the wiring arrangement.

Jim Whittaker I have purchased a 12 volt conversion kit and I am installing an ignition start switch. I have tried following the supplied instruction and have gotten lost. Can someone Help me with a simplified
version for wireing this system?
Thank You

Travis The starter selnoid that came with the tractor uses ground to close the contacts, you either need a relay or a new selnoid for the starter to work on a 12 volt ign switch. The starter switch that came with the tractor will work fine and it has the safety interlock feature, but if you must it will work, but it will start in gear. All you need the ign switch for is to turn off the power to the coil to shut off the tractor. Wire the coil to the ign post and lights to the acessory post, only use the start position If you replace the starter selnoid or use a relay to control the ground start of the old selnoid. I hope that helps
