Well, between all the newsgroups/forums I've been reading, I've been able to
assemble a working system. Thanks to all of you for your help in getting me
setup, I greatly appreciate it. What I've been able to gather is that a CD
ignition system functions exactly like an alternator, so it supplies a tach
feed that is usable, (grey wire) even though it cannot charge a battery.
The only thing that isn't totally clear yet is whether I should use a 5 pole
setting or a 6 pole. I purchased a used tach this afternoon, and it works
beautifully off of the stator feed.

Thanks again everyone!

I'm trying to put a tach on my '79 50hp Johnson (which has no alternator),
and all I seem to be able to find are tachs that require an alternator
hookup. Does anyone know if it's possible to modify one of those to work
for
me, or know of a tach (other than the TinyTach clipon, I want a dash mount
gauge) that will work? Any help/tips are greatly appreciated.
