Finally found a hood ornament for my 1959 Dodge Coronet. Thanks so much to challenger340 who had one in his collection and was kind enough to let me purchase it. My car is one step closer to being complete. Thanks so much challenger340...my car and I really appreciate it.

Good morning and Happy Halloween!!
It's been awhile but I've made progress on the 1959 Dodge Coronet. The engine is done and installed. (Thanks to a member here named Finsinthemirror for having a good engine core for me to use!!!) All fluids, etc changed. Engine spins over great, fuel and cooling system work great. The ONE problem is I have no spark at the plugs. I've checked the battery and have 12.5v. At the resistor I have 12.3v on one side and it gets reduced to 6.3v on the other side going to the coil. At the coil I have 6.3v. When I crank the engine there is spark at the points and the rotor spins. I pulled the cable from the coil to the distributor cap and there is spark from the coil. Just nothing getting to the wires. I did install all new cap, rotor, wires and plugs. I swapped the rotor and no change. I did set the distributor at TDC watching the intake and valves close and the crank mark at about 10 degrees BTDC. The distributor was point slightly past the #1 cylinder (but the only other option was 180 degrees the other way) so thinking it should be in time. So, will try another cap. Just can't figure out where the spark is going if it's coming out of the coil into the cap and then going nowhere with the points/condensor working. Could it be grounding out in the distributor? Any help or guidance from this wonderful group would be appreciated. Here are some pictures. Thanks!!

Thanks for the compliment!!
Checking with a spark tester in line between the plug wire and the spark plug. Also put a known good plug in the end of the spark plug wire and ground to engine and no spark.

Here’s a simple question:
Does it have a rotor?

Please actually read the post before making that kind of comment. As I said in the post "the rotor spins" AND "I swapped the rotor and no change".

In talking with some other forum members, I'm thinking maybe the 6v after the resistor cuts the 12v down going to the coil may be to low. Should the coil be getting 9-10volts? Maybe I will try bypassing the resistor and run a lead from the battery to the coil to give it a full 12v to check. Will keep the group updated. Thanks.

Look for any type of grounding between the distributer and the coil.
And yes, I did this accidentally in my youth: Reversed the two wires on the coil.

Will also need to rebuild the carb as the needle and seat don't seem to be sealing. Does anyone recommend any place in particular for a carb rebuild kit? I see one on the Mopar mall. Thanks.

Well, was able to bypass the power from the resistor and run 12v directly to the coil. Cranked the engine over and there was spark at both the spark tester and a spark plug. I measured the voltage again before I jumped it and it was 6v. It looks like the resistor is either bad or the wrong one as a direct 12v works.
