wiring

[marc walker]

I am in need of some wiring advice. I have copied all past wiring post for Farmall A and SA but have misplaced them.
What I have is a Farmall A with a c135 engine with bits and pieces of wires.
1-It is 12 volt neg ground.
2-It has a two wire on/off switch.
3-A two wire starter button.
4-A 4 flat post car resistor.
5-A solenoid with all the wires on one large post, I guess it was used as a junction point.
6-coil.
7 Battery ignition.
8-A 3 wire delco alt. with 3 wires 1 large red on back, 2 on side red/black
A simple point to point diagram would be really appreciated I would like to get it running over the holidays. Thanks to anyone with time to help. Thanks again Marc

Check the archives and you should find a number of them. I know how to do it but hard to explain here in words. I can do a wiring job like that in my sleep but then I have done lots of them and am a Former Navy E-T so simple tractor wiring is child's play

Marc--not quite sure if this is what you are looking for but Bob has a great set of diagrams here! Good Luck and MERRY CHRISTMAS!! Steve

Assumes no relationship to a old diagram, and makes it correct. Use colors and make a diagram as you go.
Starting with the on off switch From the starter motor big terminal, a 10ga wire should be connected. In that wire near the connection at the starter end should be a 50 amp fuse link (mechanically connected, not soldered)
From the fuse link, a 10 gauge wire goes to the amp meter (probably + side, but they are marked wierd, so it may be the reverse of that connection)
From the amp meter output side, one 12gauge wire should go to a fuse (10 amp) that supplies the ignition and start button.
From the fuse take a 12ga wire to the ignition switch Bat terminal.
From the switched side of the ign. switch go to the ballast resistor (measure about 2 ohms from the terminals out of the 4 on it.)
from that same input terminal on the ballast resistor terminal(from the key) use a 14 gauge wire to connect to a 3 amp diode (connect to the end with no band, of the arrow pointing away from theat end toward the other)
From the diode go to the #1 terminal on the side of the alt.
From the ballast resistor output terminal use a 14 gauge wire to connect to the coil positive terminal. From the negative terminal of the coil use 14 gauge to connect to the distributor side pass through. (be sure not to let the pass through be grounded to the case where it mounts)
Back to the on off sw.
From the input (non switched) side of that device, run a 12 gauge wire to the starter button. From the starter button, connect the same color/size wire to the starter relay(soienoid) This assumes the starter is not setup as was original, but has a relay (ford looking device like a small can with 3 or 4 terminals on it)
If it has 4 terminals, the "I" terminal connects with a 14 gauge wire to the coil + small terminal.
If no "I" terminal ignore the above connection.
From
Hook that wire to the S (small) terminal on the relay.
From the amp meter output side run a 12 gauge wire to the light switch fuse.
From the output side of the amp meter, run a 10 gauge wire to the alternator big terminal on the back. From that terminal, run a 14 gauge wire to the #2 terminal on the side of the alternator.
Use black plastic tape to bundle the wires nicely.
Use crimp on connectors that are bare, solder them and then use shrink tubing to insulate them.
This should get the job done and is correct.

If I use FARMALLBOBS #5 diagram to wire this Farmall, What changes or additions Do I have to make to add a 2 wire push button starter? Thanks Marc
