Hi All.
Had a job starting the engine away from base, Starter turned the engine over OK
but there did not seem any spare electricity for electronic ignition system,
jump leaded it from another battery and away it went.
The battery is a Odyssey 680 which give 680amps for 5 seconds dated 2008,
installed
09 2009 so 5 or 6 years old.
However bought a new one, put a volt meter on the new one, 12.87v
tried it on the old one 12.95v ?????
Anyway the new one seemed to turn the engine over quicker and it started
straight
away .
I know a cars Alternator output is 13.8v,engine running, but on the aircraft
using
a volt meter on the battery, I was getting about 13.05v charging rate, switched
on all the electrics and it dropped down to 12.6v
Do I have a problem.????
Many thanks
Alan
