How do you bench test a #7778A12 mercury switch box
I swap it to another group of cylinders, and check results (spark test/read plugs).
I've got several I want to test
I put my meter on 20k ohms and I get a 14.00 is this good or bad

There is no published meter test for this switch box. I think yamaha has a test spec sheet for theirs but not Merc.
+1 process of elimination test all else replace boxes in pairs
