Last weekend I was driving between the woods and the house and heard an arcing noise then the truck died. Turned out the battery cable had come loose and bounced off (disconnected). Arced the post up pretty goood. Wouldn't start again. Have worked on it some and found the following. - 6 volts to the coil, - points will spark (bright blue) when I open and close them with a screw driver (when the lobe is set where they should be closed) - No spark at the plugs (best I can tell trying to crank it with a screwdriver jumping the starter button on the firewall. -Testing for continuity I have continuity from the plug inside the center of the cap to the coil end of the coil wire. ???????????

No surprise there, a lead acid battery will hold good enough voltage to spark when it is lightly loaded, and drop into no spark when a 350 amp load is applied. Jim [Reply]  [No Email]

I was ready to go to town and buy a condesor on monday. Had put it on the charger overnight, tried it again this afternoon and it started. Not sure why it wouldn't all week but did today. Thankful, dumped the load and parked it inside. [Reply]  [No Email]

Put it within i/8 inch of the engine block (tuck it in so you can let go of it and it will stay in place.) now with the key on, move the points from closed to open to get that blue spark at the points. If no blue spark at the coil wire to block, replace the coil. Jim [Reply]  [No Email]

If no blue arc when points open you will have no spark. Short could have damaged coil to where it will make some arc but not enough to fire the plugs. Try changing the condensor first [Reply]  [No Email]
