Terminal block or resistor?

1951 side mount distributor

Okay I have had a few conversations with some manufacturing maintenace guys and even printed out the wiirng diagram for a late model 8n with side mount distibutor.

Is the terminal block 8nnn-14448 listed in the wiring diargams in the FO-4 manaual a resistor or not?

Why can this replacmeent number not be found on replacement parts sites?

If it is the standard two prong resisitor, how does the flow of voltage to the coil get stopped if the switch is in parallel?

In the off position, will voltage not flow through the resistor?

Like Bob says, use a NAPA IC14SB Coil Or equivalent coil, (IC= ignition coil-- 14 = 14Volt rated -- SB cheap'er line my guess) also a OEM style Terminal block izz just plain nice to have to tap onto, money well spent, git'er changed out and life will be good.

What I really dont understand or need to know is do I need the standard two prong Ford resistor used in 12 volt conversions and such forth or does the late model ford 8n original 6 volt round can coil and 5 nipple distibutor even need a resisitor?

I am thinking more and more that the terminal block 8nnn 14448 listed in the FO-4 manaul is really just a termianl block for mulitple contact points and this electrical system does not need in-line resistance before the coil.

If I could get past this mental hang up, I would try and crank her.

Otherwise, I might wait to use a volt meter and drift away from the original 6 volt FO-4 diagram.

 Terminal block , NO resistor... in reply to SCgoatfarmer, 08-09-2006 13:24:45  
Simple answer.

From the factory, the side-mounts used a true 6-Volt round-can coil, and NO resistor, just a junction block.

So, if you are still 6-Volt, no resistor, no problem.

If it has been converted to 12-Volts, get a TRUE 12-Volt round-can coil, which will also NOT need a resistor.

So, either way, you can enjoy a resistor-free life with your tractor!

MUCH simpler than if it were an older unit, with a front-mount distributor.

That is what I was leaning towards and how I needed to hear (in very simple terms).

Alright then, so if I dont have a junction box, what do I do then?

Can the ignition switch be used as a junction location if the electrical fittings are small enough?

Well if you have switched it to 12 volts but still useing the coil that was on it then you need a resister bewteen the switch and the coil. Now if you buy a new 12 volt coil and it has to be one that says something like internal resistor or no resister need on it then you don't need the ballast resistor.

SCgoatfarmer, A terminal block is "NOT" a resistor. It is simply electrical terminals/connections that allow separation of function.

The "Front Mount" Terminal Block has its Ballast Resistor mounted between the top two terminals.

Hope this Helps.
