8n Front mount distribitor 6v

I have an early 8n. Still six volt.
I rebuilt the steering so with I had to remove some wires.
I had marked then all.
Bought a new 6 volt battery. Got everything back together. Double checked wiring against manual.
No spark.
Then the wire that goes from the terminal block (has other wires besides on it)to the negative stud and negative cable from battery, burned up.

Help!

Sounds like the terminal block may have been damaged, causing a short, or one of the wires connected to it is somehow shorted, or a wire terminal is turned and contacting something that is grounded.

The resistor block and terminal block are one in the same?
I know that the resistor has two connections and then there is a third bolt that has about 4 wires going to it.
Can you explain how works? Doe sthat supply a voltage to all those wires? Because teh wire that burnt had voltage as it was on teh same stud asthe Neg cable from the battery.

" The resistor block and terminal block are one in the same?"

While the terms are commonly used to mean the same part, your tractor has a resistor block......that's a terminal block to which a resistor is attached. A terminal block, used on mid-50's to 52 8N's, did not have a resistor.

" Doe sthat supply a voltage to all those wires?"

Google "wiring diagram JMOR" to get a visual of what it's supposed to look like wired.

The center post is the "common"; all but 2 wires attach there.

The top two posts are for the resistor. Attach the wire to the coil on the left & the wire to the ignition switch on the right. That puts the resistor between the switch & the coil.

As to your problem......

Make a visual inspection first, compared to the JMOR diagram. You will probably find something burnt at the short.
