Does anyone know of a good wiring diagram for an 8N (Front Mount Distributor) for a 12 volt conversion? I am not sure if I have this done correctly or not...the instructions in the kit were less than clear. The alternator the dealer sold me has a single post as well as 2 available prongs. The dealer indicated that I only need to connect to the post. Any help or diagrams out there ?

If you use just the wire on the post, you have to rev the engine after you start the tractor to excite the alternator. That means it won't charge until you rev it. I like to do it that way, keeps it simple. Using the spade terminals like the other guys said lets the alternator start charging as soon as the alternator starts turning.

Roger: You should check out Gennesse's website listed under Parts & Supplies on this website. They have under the 12volt conversion section a good explanation of what wire goes where. I used their wiring directions (using a voltmeter instead of a ampmeter), and it works perfect. I believe the "resistor" that JRH_9N is talking about is actually the DIODE. Anyway, check out Gennesee, I used their kit and directions and I couldn't be happier with it.

Your alternator sounds similar to mine (post to battery circuit, and two 'prongs'). Mine is a Delco (not sure what part number). On mine, the two prongs are wired together, and run back through a resistor (maybe 150 ohm) to the ignition switch. When the ignition switch is turned off, power is removed from the two prongs.

It is my undertanding that the resistor prevents the tractor from continuing to run when the ignition switch is turned off, by limiting the amount of current that can be delivered by the alternator through through this secondary path through the two prongs.

I believe one of the functions of the connection to the 'prongs' is voltage sensing. On mine, if I disconnect the connector to the prongs, the alternator will not charge the battery.

Claus is the real/ best guru here on this subject. And I'm sure the archives have schematic diagrams for 12 volt conversions.

Not much help maybe, but just my thoughts. Good luck...

Jim
