400 won't start, what next?

[super99]

A week ago, I used my 400 Farmall and let it run for about an hour since it hadn't run in a month or so. Tuesday nite I went out to start it, it turned over but wouldn't fire. It was drizzling, and I thought it was just damp and would start when it dried out. Tried Wednesday, clear out, same thing. I did some checking with my tester and there is power at the resistor before the coil and power going into the coil, but no power coming out of the coil. The general answers from here were to change the points and condensor. I put new points, condensor and rotor in this morning, and no fire at the points. I am guessing that the resistor before the coil is to change it from 12 volts to 6 volts? Is this right? The test light is brighter on the inlet side of the resistor than the output side going to the coil. What is the next thing to try to get it to fire? Chris

Open the cap and (if it has one) remove the rotor and plastic divider plate to expose the points.
Put a corner of a dollar bill between the points. and leave it there.
Turn on the ignition sw.
Use your test light as before, test the input side of coil, and now the output side. If it now lights, the points may need a little bit of 320 paper used between them to get the factory goo off of them. If there is no light, one of two things are happening.
If the little stud that goes through the side of the distributor is grounded on the case it will not run.
If the coil is open inside (bad) it will not run.
To check which, take the wire off of the distributor terminal and than check to see power on the coil side that is opposite the resistor. If no power, the coil is open and bad.
Good luck, JimN
