I just inherited a 1989 35 hp merc and its not charging. I've only
checked the voltage at the battery (closed) but I never see any thing
more then 12.71 volts. This doesn't change with rpm.

I was wondering if someone knew how to test the charge coil and
rectifier. I'm new at this and would really like to fix this myself.
