On the first picture the wire from the capacitor looks like it has been pinched/cut. On the last pictures the wire looks like it laps over the edge of the metal housing. When you push it back in the housing to install the cap maybe the wire touches the housing and shorts out. You were getting close and then replaced several parts. When you do this you bring the possability of more bad or incorrectly installed parts. chuck

49, no the wire from the cap isnt cut or pinched. I tried to see if i could get spark from the points with the cap of and the ground wire didnt look like it was touching anything but i will double check and make sure it isnt. I seen at another forum about inline 6 ford engines that the gap is suppose to be set at .25 so ill give that a shot to. Who knows tomorrow i should get the new distributor i ordered last week and if this fails tonight ill pop that in and see what happens i guess.

Tell you what, its got me stumped. The new distributor might be worth a try, but Im not sure after all the work, and checking you did why there would not be spark..

YAY, finally she fired up. The problem was when i tightened the wires up comming from the coil had been touching the body of the distributor so it was grounding out. tomorrow i will replace the fuel pump with a new one and see if she will suck gas out of a gas can so it will run longer that the 3 seconds from the shot of either....

good job. I would be very careful replacing parts in the future when you have a issue.
In most cases you can get what you have working enough to get it running. Then when you replace something and have issues you can narrow it down to the new parts.These old truck are fairly simple if you just work through your problems one step at a time and don't get frustrated and start replacing parts, having no idea whats wrong.
Congrats on getting it running

What a mess, the wire to the coil is supposed to go through the white thing but hang on for now; I have sent a PM Julie who has a wiring diagram for you.

Are you sure that the white # 1 wire is from the ignition switch? If the power from the ignition switch does not go through the white thing (ballast resistor) your points will burn in no time. Also there is a small wire from the S terminal on the starter solenoid that also goes to the coil bypassing the white thing to give 12 volts when starting.

As far as i know it does, it comes on with the key on. So there should be 2 wires going to the hot side of the coil? Im wondering if i should just spend the 200 bucks and get 1 of those ez wiring kits for it, it sure would clean it up.

Well, congratulations on getting the old girl running! I might be tempted to go buy a Lottory ticket - your pretty lucky!

I looked at your pictures and Old is understating a little - that wiring is a disaster. I tend to be a perfectionist - spend the $200 and get the EZ wire.

The signal flow on the ignition wiring is very simple: Power flows from the "Ign" terminal of the ignition switch to one terminal of the "White Thing" which is a ceramic block holding a "Ballast Resistor."

So, in from the ignition switch to the ballast resistor, then out from the OTHER terminal on the resistor to the positive post on the coil. The negative post of the coil runs to the distributor and the points. As you discovered, nothing can be chaffed or bare to ground out.

Now there is one more wire on a 12 volt conversion. It runs from the "I" terminal on the Starter Solenoid and is tapped into the wire running from the ignition swith to the ballast resister - before it gets to the resistor. You can do that one of three ways: you can run it directly to the "Ign" post on the ignition switch; you can run it directly to the post of the Ballast Resistor that is connected to the "Ign" post of the ignition switch; or, you can slice it into that wire anywhere between the two (ignition switch and ballast resistor). See the diagram below. Note that it is for a one wire alternator - which I don't think you have. But it's not related. The ignition circuit and starter button flow is seperate and that is what yours should look like. Busses are the places you are distributing power out of - like a fuse block. Hot is on all the time (lights, brake lights, etc). Switched is turned on with the key (heater, radio, etc). I'm not going to guess at how that mess is powered or distributed. After awhile, it should all be replaced, and we can help you with that.

I noticed that your primary ignition power wire goes into the ballast resistor then out from the same post, that's wrong, and I don't know what you have connected to the other side of the ballast resistor???????

Anyway, if you ever need wiring diagrams, you can check out my #4 gallery - there's lots there. Or if you ever have any questions, just send me an e-mail - I'll be glad to help.

Now I am confused. The "I" wire comming from starter solenoid is supposed to be supplying 12 volts directly to the + side of coil, bypassing the voltage drop thru ballast resistor. What am I missing??????

Good question and I'll confirm it, but this way the extra charge comes out and is reduced as well making the total from the two sources 12 volts. If it was the other way you would have mnismatched voltage - 6 coming out of the resister and 12 coming out of the solenoid (remember that voltage drop resistors are commulative in nature reducing both voltage and amperage. And amperage at 12 volts is really what you are looking for during the "suppliment" and what the reducer actually needs to lower for normal operation).

But, I'll check just to be sure.

I think the wire from the I post on the sol. goes directly to the coil. That supply's full voltage only during the start cycle. When the sol. retracts then coil voltage returns through the resister lowering voltage to prevent point burn up.At least thats the way 6 volts work and no reason 12 would be different. It simply bypasses the resister to provide full voltage for easier starts.
But then I am old and mostly senile and could be wrong.

Except there are no ballast resisters on 6 volt systems nor is there an "I" post on a 6 volt starter solenoid, just the "S" post for the starter button. I think the drawing is correct.

Actually, I heard somewhere here it could be done either way. All you are looking for is the boost from the solenoid. It's still going to work even if it gets reduced down.

You may well be correct on the wiring. On the old ford cars, there is a resister under the dash on the firewall. It reduces the voltage going to the coil from 6 to 3 volts. It was very common to go from the starter side of the sol. to the coil with a wire, bypassing the resister. That way when the starter button was pushed it gave full 6 volts to the coil.
Looks like you have a lovely place to live from your trailer pictures. Sure beats N. Missouri this time of year.

I used to live in St. Louis! I've never seen weather like that - winter or summer!

Interesting note about the car electrical systems. Ya learn something new everyday.
