Yes I originally posted about the underdash resistor and voltage, then reread this was about a 50 merc and deleted.


No spark is coming from something going on in the dizzy I'd guess, since you've changed out the coil and condenser. But I'd test everything. Assuming the points are good and gapped and the timing is set.
