I need a wiring diagram of a 1960 ford f-100 6 cylinder ignation coil

I don't have wiring diagram for that year.
I don't mind talking to you.
The positive side of the coil gets voltage from ignition switch, the negative side of the coil goes to distributor and ignition points on a points type system.
Some makes and models, when cranking, everything gets full battery voltage. When it starts and you release the key it springs back to the run position. In the run position, voltage to the coil may go through resistor block or resistor wire, the purpose is so the points on a points ignition doesn't have to deal with full battery voltage all the time. Helps the points last longer.
Just my opinion.

What is the dwell angle on a 3f engine if point gap is 18 thou

dwell angle is the no of degrees rotation between points closed and points open and for example on a 4 cylinder engine ( 4 lobes =90 degrees the dwell would be around 45 degrees available
there is an adverse relationship between point gap and dwell angle
the closer the points the bigger the dwell and conversely the bigger the gap the smaller the dwell angle
in a distributor the point gap of 18 would have a large dwell angle and that affects ignition timing
in your workshop manual there will be a dwell angle specification and if you set the points at .020 " that will put you close to the dwell angle specification
from there you adjust the gap to obtain the dwell setting
after yo have the dwell set , adjust the ignition timing
there is plenty of information on dwell angle, /point gap if you type in ---dwell angle to point gap relationship--

What is the ignition point gap?

In older engines with traditional points-condenser-coil ignition systems the dwell if the ignition was set by the gap between the points. The points act like a switch that opens and closes the circuit of the primary side of the ignition coil.

All later engines use electronic ignition that do not require points.

What is the points gap?

Points gap was used before electronic ignition. The "points" were a set of contacts found under the distributor cap and rode a cam that opened and closed them at the firing point you set with a timing gun (a gun shaped device that flashed light, when the first cylinder plug fired) aimed at a scale on the front of the engine overhanging a mark on the crankshaft pulley. The points were set to a gap suggested by the manufacturer.

How to set points gap massey 35?

you have to bring the cam around till it opens the points fully and then you set the gap. if you have a dwell meter and you have a window on the side of the distributor or cap you can set dwell which is setting the gap, just more precise ( although you may not have this window

1967 ford mustang coil is getting so hot it turns of could this be from my points not gauged right? Plus at idle it sounds rough where do I start?? Help please

I would check voltage to the coil

It should be less than 12 volts

Iam a 1960's guy, but don't remember the exact voltage
There should be a resistor before the coil

Points are set to a specific gap or you use a dwell meter,
at least back in the day

The distributor needs to be on a clean surface ,so the points
& coil can ground out properly.

The idle could be valves,vacuum leaks,carb,any number of things

You may want a grounding strap from engine to body & sub frame

Check the alternator for AC Leakage (current ripple)

1964 292 engine how to set the points gap what is involved

There are feeler gauges (extremely thin) to adjust the points gap. First find the proper gap for your model vehicle, and then purchase a gauge. these gauges have something like 10 different thicknesses, for different points, so make sure it includes the exact gap that you need. I remember in my youth adjusting the gap with cigarette wrapper paper, it seemed to have the proper thickness to get you out of dodge. Also remember that you have to rotate the engine until the points are in the open position, in order to adjust them.
