The dreaded electrical Gremlins strike again!!

My partner was thinking that the problem went away when the engine
smoothed out at the highter RPM. I asked him if he pulled back the power
on the way back from Oklahoma to see if he could get the avionics to
crap out again and he said "Hell no" I just wanted to get back. Can't
say that I blame him. :-)

The post stated that the problem went away when high engine RPM
was used, meaning that the alternator/regulator/battery
combination was not producing enough energy to satisfy the load
at the lower RPMs.

I'm not yet convinced that a ground problem would be overcome
by higher RPMs. (unless it's some wierd resonance effect g)

Hmm, another though has just occured to me.., what if the
battery has a shorted cell ?
That scenario would cause low voltage at the battery and the
regulator will try to send a *lot* of current into the battery
in an effort to get it back to nominal.
