Let me do a quick run down. I have no spark out of coil. I'm using an inline spark tester on the high tension lead from coil to distributor cap.
Coil is new (3rd one)
Ignition sensor new (few months)
New batteries
New cables
New plugs
New plug wires
New starter
New ignition switch
I have run the TBIV test and it kind of points to the ignition module. However, sometimes the spark just comes back after working on something else in the boat. I took a couple of large waves over the side of my boat a few weeks back which shut everything down and the boat wouldn't start. It appears that the module connection got inundated with water/corrosion so I removed, cleaned, and added new grease where it connects to the distributor and it fired right up. I went to get a new timing light to reset timing and now, NO spark. This boat has had a consistent electrical gremlin since I purchased. I did find a worn through battery cable that was grounding to the engine so I assumed I was getting excessive voltage drop and that was causing my electrical issues. However, now that everything has been repaired, and the engine has run, I'm not sure why it doesn't have spark again after only 30 minutes of me going to get a new timing light. Could the fact that the distributor clamp bolt is an avenue of grounding the ignition module? I only loosen the bolt just enough so I can turn the distributor. I'm going to run through the tests again and clean and tighten the clamp and check for spark again. Any help would be great. It's like one day there will be spark...it'll run, then pow, nothing. Coil does test on the bench as well. Charge the positive side, release, and there is spark... My left arm is sore because of holding the spark test incorrectly.

When I went to plug red/white bullets back together, it sparked through the hi-tension coil wire lead indicated by my inline spark checker. I could unplug the red/white and do this but it only did it a couple times then quit. I would think with the key on, the coil should charge, and when the red/white bullet connectors are connected it should discharge the coil every time. Why only a couple times then quit?
