burning up coils?
I have a 72 f250 highboy the 360 in it was vapor locking. When it stopped that after new plugs wires distributor and fuel pump. It just died acting like no spark. Once I put a new coil and battery truck started and ran. Drove abt 4 miles parked it the when I tried to start it again bam right back to no start any idea's?

Are you using a coil with the resister in the coil or a external resistor ??/ or are you familiar that you even need to use a resister between the coil and distributor ??/ What are you running points ,Duraspark, other ??/ what do your points if your running points look like after you lose your coil ??/ Are you using a cheap after market coil ??/ Any combination of these occurrences could cause you problems not saying that's the cause of your failure but its a start ??? Also each system ( Distributor ) uses a different OHM resister some may not even need one( Mainly
the electronically triggered ones ) ??/

Sounds like you are confusing resistor with capacitor/ condenser. The tubular part in distributor is the condenser, one by voltage reg is a noise filter. The resistor wire is behind the dash in the wiring harness between ign switch and firewall. My guess is you have replaced coil with the wrong one. Most are marked for use with internal or external resistor. For use with external resistor is the one you need. Primary reading across +/- posts should read about 1.4 ohms. Standard for all older Ford vehicles, points or Duraspark.

Condensers (and coils) often fail only when they reach operating temperature. Something to beware of.
