    Also, on the block where the starter is mounted and behind the steering linkage are raised letters "8N"

    It isn't just as simple as a dead battery, is it? I haven't read that you checked that.

    as suspected. you DO NOT have an 8n. you have a 9n or 2n. and it is somewhere before a mid 44 model.. as it has i beam radius rods. .. Oval came out in 44.

    big difference.

    no solenoid on a 9n/2n.

    and the trans safety interlock switch is a mechanical starter switch. not a grounding switch to a solenoid.

    can't help you with your problems without knowing what tractor you had.

    essentially same wireing except you remove the old vreg and it's field wire. take the old armature wire. one end goes to alt charge stud.. other end goes to bat wire that was on vreg.

    add in your ballast resistor or get proper coil.

    if a 3 wire gm 10/12si alt.. jump charge stud to #2 terminal. take #1 terminal thru a 194 lamp to the hot side of the key switch ( good use of that old field wire ).

    change out lamp elements and fuse for new elements. change battery.. make sure ground polarity matches alternator... usually negative ground.


    if a round can coil.. make sure it's (-) side goes to dizzy... if negative ground.

    'bout it.

    I have a 1949 8N front mount dist. and the 3 wire GM 10/12si alt only reason I'm changing is the generator fried and I had the alt. just sitting here anyway I'm just not crazy about doing the wiring changes.
