No spark on my 84 Ram.

Plus + on + side of coil or better yet somewhere before the coil. - goes on ground not - side of coil.

It see's 9.6 volts with the dmm on the + side of the coil, and the - side of the battery while cranking.

Try checking the ballast resistor to see what the voltage is going through it. Also check with your meter on the + side of the coil and chassis ground with the key it the on position. I have seen this happen many times over the years. There will be no power to the coil during cranking, only in the run position.

Could be a body ground strap from the fire wall to the engine.Must have a good ground or it won,t fire.

I'm getting good voltage at the resistor, better then my Dart.

I was thinking a ground problem since it was so intermittent before now. I had a problem with the dash lights acting all stupid at random on the Dart last year and it turned out to be a ground that gave up the ghost.

I also noticed that after cranking the neg cable is pretty hot, where as the positive cable isn't. Which indicates resistance. I have the ground going to the block (head actually), then another strap running from that point to the frame. Been like that for a few years though, doesn't look corroded, but that doesn't really mean much.
