Re: No spark
 
Get new points and condenser and gap it correctly.

The meter read 0.18. Shouldn't it read 0?

If I understand you correctly, you measure the resistance of the wire from the coil positive side to the wire that goes to the ignition switch. It will not read 0. The wire from the coil positive to the engine connector is a resistor wire (ballast resistor). The wire from the engine connector to the ignition switch should be a plain wire. The reading you have seem to be low. In my 1964 GMC manual the V6 should be 1.5 Ohm.

Your exactly right James. I was reading the ohms thru the resistor wire and plain wire. I ran a wire from outside the cab from the resistor wire to the inside of cab to the wire that was hooked onto the IGN iginition switch. This is where I thought the problem might be. I think I will purchase a new condenser and points like Ken said and go from there. I love this site and all the help I have gotten on this site. It's just so wierd that when I drove the truck into the garage it ran great but something happened that I did to cause this. Thank all of you so much!!
