Although I'm a far cry from an expert with points and distributors, my neighbor has a problem with his 1966 Case 730 Gas Engine firing. He is getting fire, but not out the cap to the plugs. Here is what I have found so far:
New points and cap on the Prestolite Dist.
Rotor checks good.
Wire from Starter to + on coil
Wire from - on coil to distributor.
Points are gapped and firing correctly.
When the key switch is on, there is fire to the coil and back to the dist.
When the engine is turning over, there is no fire out of the cap, but with a test light on the - terminal from the coil, the test light is lighting every time it fires. This is with the test light grounded and touching the - on the coil. The test light is bright when it is firing. If you take the test light and then put in into the dist cap, there is no fire.
Any thoughts on this? Tried a second coil that I know is good, and the same thing. Thanks for any insight. Bob
