At Sun-N-Fun, discovered battery getting weak while trying to
relocate aircraft from one mudhole to another. (FYI, they have an
excellent volunteer aircraft repair group there that will fix your
airplane but you have to buy the parts). Had generator tested
by "Buddy" downtown and he said it was "burnt". Found another
correct generator at the Aircraft "Fly" Market on the field and it
checked out good so installed same. Still no charging so another
good Ercouper who shall go unnamed (thanks Bill) just happened to
have a new voltage regulator in his Coupe that he for some reason
threw in at the last minute. Installed the new voltage regulator and
still no charge (+) indicated on the guage. I get a decrease when
the landing light is on, but no increase after start or other load on
the battery. Any ideas? Anyone?
BTW, y'all missed a good show. The Mustang ride was the best.
