2000 gas no fire

My 2000 model gas converted to 12V several years ago and has always started and run fine. Yesterday tried to crank it but would not fire. Gas flow thru carb is good. 12V to coil and to distributor and to points but no spark either at the points or on wire to plugs. No spark thru wire from coil to distributor, (not sure what should be there) but continuity on wire from coil to distributor is good. Have replaced coil and condenser but still will not fire. Any suggestions will be appreciated.

eeing as how your measurement/results do not add up, in my book anyway, I'll assume that a sensitive meter is yielding bogus conclusions. So used a 12v bulb test light & probe all those same places as well as directly from one point contact to the other, both with points open & points closed.
If you like sparks and arcs, I do, then quickly "sweep" a grounded wire across input to coil (spark means power good from ign sw), across distributor side of coil (points open or distr to coil wire disconnected) (spark means continuity thru coil). This last one should produce HV at coil tower.
 
No spark at the points means one of 2 things. #1 the points need cleaned or replaced or #2 the insulator going into the side of the distributor is shorted out. But since you say you have voltage at the points that can only mean the points are dirty or bad
 
I'd check dwell with a meter, you can get a rough test on the coil with continuity testing (I always have to open a book or do a web search to recall where to test), might me as simple as a bad condenser.
 
Thanks for the responses. Found the problem. Turned out the copper connector from the coil terminal that passes thru the distributor housing and connects to the points, after 50 years decided to move. Just so happened it moved against the distributor housing, thus a short. I must add that this connector showed signs of less than careful attention over the years. It was pretty well mangled. Anyway, we are running now. Hope to move some hay bales tomorrow.

lad that you got it fixed! Remember when I said all the measurements didn't add up? A short at he copper strip would have precluded, " 12V to coil and to distributor and to points ". :)
