I recommend that you not do that just yet. It is probably a good thing to consider for the future, but right now it is important not to do anything that might set you back. Wait until you're back on level ground. > When I'm done with that I'll look again at all those grounds and other > wiring paths with the VOM.

Yes, I think I would specifically check another set or 2 of trigger points. When you're done, I'd like to at least see the ones that you had that were bad. BTW, it's a good idea to lube the trigger point cam with something. The Bosch cam grease is perfect for this. Running either dist cam dry will lead to rapid rubbing block wear. > > This is a pretty good test. Do it again WHILE the engine is running > > on just 2&3 (failure mode).
