The problem is with the EIS=2C only why did it coincide with a battery move
?
I checked the voltage in the panel and everything looks fine with the main
system.
The EIS gives good readings with the engine off. Thde only anomaly is the v
oltage which says 11.0=2C when it should be 12.5.
When I start the engine the readings go haywire: oil temp is below of what
is possible=2C pressure is 99=2C cht is 900C. After switching the EIS off a
nd on a few times the readings are good. But then the numbers start bouncin
g around again. Of course Grand Rapids are closed for Oshkosh until Monday
=2C and I am not sure what to do.
Any other ideas ?

Hmm..Not sure=2C
My first thought was along the line of what Ira had said..bad ground somewh
ere.
Try making some measurements between the power and ground rails with a han
dheld meter to confirm what the EIS was reading. Take the measurements with
the key on and the engine off=2C to eliminate all chance of actually produ
cing deadly avionics voltages from a spinning alternator. What is the EIS r
eading in this configuration(engine off)? Could there be something that was
connected to the rear-ward wiring that became disconnected when moving the
battery up front? Is the ground strap to the engine block still connected?

This one is for you electric specialists:
All I did was to move the battery back to the firewall from the rear fusela
ge. I fire up the engine for a highspeed taxi test for my MG configuration
and I get a voltage reading of 25.
I swapped regulators - I always carry a spare - but no change. I also get
the same reading with the alternator switched off. What could I possibly ha
ve screwed up ?
To make things even more perplexing=2C the oil pressure indication does not
drop below 93=2C as the engine is warming up=2C but maybe the two are some
how related. All readings are from the EIS. Never had a problem like this b
efore.
Any help appreciated.
Thanks=2C Karl
