I have a question regarding the replacement wiring kit for a 6 volt 8N. The wiring kit has 4 wires which go to the dash - 1 wire goes to the starter button and the other 3 go behind the dash to the anmeter. Which specific posts do these 3 wires go to? One is a longer thick wire which has a plastic covering on it - I believe that goes directly to the anmeter. The other 2 are smaller wires - where do they go?

No one can tell you where a thin wire goes or a thick wire goes. What we can tell you is that the wire that comes from the Generator Field terminal hooks up to the Field terminal on the Voltage Regulator. You must specify where one end is hooked to in order to tell you where the other end goes. If you can follow wiring diagrams check out the following site. Otherwise you must specify where the other end of the skinny wire is hooked to.

I have viewed this site many times, but it doesn't do much for me, since it does not refer to wire colors and does not really show the exact number of wires included in the wire set. Also, the voltage regulator referred to on this site is different than the one Ford New Holland sells. The regulator on the site shows the 4 wire connections on 3 different sides of it, while the actual regulator sold by Ford New Holland has 3 connections on the bottom and the fourth connection attaching to a ground screw. Who is right?

The new voltage regulators only have 3 terminals. The ground from the generator goes to the case of the voltage regulator and to the positive of the battery. (At least that is the way I have mine wired. This assures a good ground connection to the VR and the Generator.) I make my own harness, this way I cannot go wrong.. The older voltage regulators had a ground terminal sticking out that is why most diagrams show 4 terminals. You cannot go by colors except that it helps when you put a (Example) yellow wire to the field of the generator, then you must put the other end to the field terminal of the VR.

Ok...since I have some time this afternoon and it is raining outside, I will do this for you:
Frontmount:
1. Wire from the top of the coil goes to one side of the ballast resistor.
2. The other side of the ballast resistor goes to the ignition switch.
3. the other side of the ignition switch goes to the tie point (Middle connection on the terminal block.
4. Heavy wire 10gauge from middle of terminal block to ammeter +.
5 Heavy wire 10G. from middle of terminal block to starter relay (where the battery cable is connected to.)
6. Small terminal on back to starter relay to the starter switch.
7. heavy wire 10 G from middle of terminal block to bat termial of voltage regulator.
8. Generator field to vr field.
9. Generator ground to case of vr.
10.Generator output terminal ( Heavy wire) to generator terminal on vr.
Try that

Thanks for all the help, Claus. I appreciate it. Do these instructions also apply to a side mount distributor? I have a side mount.

The only difference is that a sidemount does not have a ballast resistor. The sidemount ignition switch that would go to the ballast resistor uses a tie point on top of the terminal block. Then the coil wire would go from that connection to the - of the coil. Everything else is the same..

When I proofread it, I found a mistake I made:
5. Other side of ammeter to the to starter relay where the bat cable is connected to..
Sustitute this 5 for the before 5.
Sorry

I have the manual that you talk about. I also purchased a wire set directly from the Ford New Holland dealer. However, the wire colors mentioned in the manual do not match the wire colors on my wire set that I purchased. Therefore, the manual does not do me much good.

Matt..... ..Color code allows you to identify both ends of the same wire. Electrons are color blind and don't really care what the color of the wire insulation is.

Now determine which wire naturally falls into place at the voltage regulator (they are usually of different lengths). Use that colored wire other end to connect to the correct responding electrical terminal at the other end per the I&T FO-4 manual schematic. Piece of cake. (unless you are color blind, grin)..... ...Dell
