Engine died. Now won't start
The coil has no resistance between pos. and neg. terminals,
Please explain what you mean. "No" resistance could mean zero ohms, or infinity.
"No" could mean that your ohm meter just is not very accurate at low readings, and if it is reading "zero" then the coil may be OK, or may be shorted
If it is "infinity" (as when the leads are not connected to anything) then it is definitely "bad" meaning the primary windings are "open"
has some resistance from the terminal to the tower David
What means "some?" There should be "some" probably several 10's of K or kilo ohms
You need to do some troubleshooting to narrow it down.
With the key on, as someone said above, there should be some voltage at the coil negative, and probably very low voltage at the coil negative.
You should be able to hook your meter on low AC volts to the distributor connector and crank the engine. The distributor pickup should generate about a 1 volt AC
Also check voltage at the coil positive "when cranking." This should be about the same as battery, IE if the battery is 10.5 when cranking, then you should see close to that at the coil positive.
I'll tell ya, I made the decision to get rid of the Mopar box and go with GM HEI, and so far so good. Stock coil, no resistor, and HEI hooked to an Accel "stock replacement" type dist, which uses a Mopar pickup coil.
I have had some trouble with Mopar breakerless pickups, and a discussion on "another board" with someone who has done a HELL of a lot of tuneups indicates he suspects that pickup coils MAY lose their magnetism -- which would explain otherwise unexplained failure
