.....


Any hints of where I should begin my search would be greatly
appreciated. I
have to pull this beast out of the hanger to run it up. With out
Northwest
weather I haven't had two clear days to work on it outside and I'm
too old
and stiff to do a lot under the panel. So any hints or experience of
a
similar trouble would really be appreciated.

I'm going to jumper the alternator field portion of the dual master
switch
to start with but beyond that ----------------


Thanks in advance

May want to check with Paul Malkasian up in Sequim, (360)683-6245, he
has a very good reputation for rebuilding all kinds of OEM Cessna
gauges. Also, before further experimentation, verify you do not have an
automotive regulator - VERY bad deal on airplanes. Unlike aircraft
units, turning off power to the S pin (turning off half of a split
master) does not cut field to the alternator, but shuts off the
regulator itself, resulting in easy 90-100V out of a healthy alternator
at high RPM.
