Okay I have a ’46 2 ton with a 216 the system aperies to be the original 6 volt but half the wires are cracking/corroding/just bad I tried to start the truck one day after weeks of tinkering with the engine to get the starter to turn the flywheel (various problems) now the distributor isn’t producing any spark, the wiring is far from 100% but I think its good at least to the distributor, my question is how do you know a distributor is fried? Is there a way to test it? Can I use the distributor cap off of a 235 on this 216 (I have the cap off a 235 that was recently restored so it should be good) I’m just wondering if it would be compatible.
