1 Wire Alternator Wiring Diagram For Ammeter. Marcus I have reviewed the wiring diagram and have a minor correction to make to what I described above. I bought a 1eZwire wiring diagram on CD and mapped out the wiring before I did the alternator and wiring change.

One wire alternators eliminate the unsightly factory wiring harness and simplifies instal-lation by using only one wire for charging. In their place goes the alternator and that one wire going to the ammeter now is the one wire coming from the alternator. First you cant run to the same side since with the 12 volt conversion we are going to use negative ground rather than positive ground that all the old tractors used.

Some other tidbits available from AC Delco for wiring up a 10SI is wiring package 1870921 for those 6 to 12volt conversions.

Remove the alternator mounting bolt with an appropriately-sized socket wrench and separate the alternator from the vehicles body about 14 inch. I should have said. The eZwire wiring diagram is much easier to read that the one in the shop manual. By Jeff Balazs July 28.
