Hi Bud=2C
Good try. There are other small batteries=2C but they are totally isolated
=2C some 9 volts for variometer and stall warners=2C and a small 12V for an
exterior alarm (to scare animals off the runway or warn pedestrians when t
axiing etc.).
I merely reconnected the battery leads to the two posts which I have on top
of the starboard footwell. I must have caused a short or ground somehow
=2C but I just don't see it.
The engine starts and is running fine=2C but I only let it run for a minute
or so.

Not knowing your bus wiring=2C
Do you have a spare / backup battery=2C and if so did it accidentally get w
ired in series?
Double the voltage and a higher than normal voltage to the sender tends to
drive the pressure up and temps down (I think=2C I may have to do some rese
arch as I may have that backwards.)
I know=2C dumb question=2C but I thought I'd ask.

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
