Seems like we checked everything. We had IA's and A&P's scratching
their collective heads over it. Fuse was OK, master switch on all
the time, ran it up to 1300+ to ensure generator cut-in speed,
flashed the field etc. Really puzzling. The latest theory is that
the master switch might be mis-wired so that will be looked at in a
couple of days or the voltage regulator needs to be set higher
because of the installed battery. There is also a big red light by
the circuit breaker panel that never illuminates under any
circumstances although the bulb looks good. It looks light it might
be a generator failure warning light.
Chasing down the wiring will be a gritch because there are also two
electrical switches, one under the instrument panel on the left side
and the other at the bottom of the panel on the right side which
apparently do nothing. I think the one on the left is for a solitary
red panel light on the left side but it doesn't illuminate even
though the bulb looks good.
But hey. The plane sure flies good.
Also, I can relate a little bit to Syd and his coupe. When I was
cleared for take-off from Sun-n-Fun, tower said "The chrome Ercoupe
is cleard for take off". Wheeeeeeee!

When in idle rpm, the generator can not produce enough energy to
trigger the regulator even.
