Not Cheap, but pays for itself in fuel savings and engine diagnostics!

just me. After all, one of the biggest causes of engine stoppages is fuel

choice for maintaining your batteries. It will not boil or overcharge your
battery. Been using mine for 4 years and my
Concorde batteries are still quite healthy. Good choice for doing gear swings or when at
the avionics shop or in cold weather climates for that extra "edge" in

Bushing #48 on the idler arm in the Part Diagram is often neglected. If/when you
change bushing #48 ask your mechanic about drilling it and fitting it with a
grease zerk fitting. An experienced Beech Lister has reported that you DO NOT
have to remove the co-pilot rudder pedal shaft to remove this idler arm. Simply
remove the outer hardware and rotate the arm aft to clear the nose gear cavity,
then slide the idler arm off the shaft!

If you fly in IMC for much at
all, please consider some form of Voltmeter or
alternator out annunciation light
for your panel. Early warning of an alternator failure or bus voltage problem
BEFORE the battery is DEAD is very helpful, IMHO.
Big airplane saving tip
follows: If you experience an alternator failure in flight (and don't know how
long you were without charging because you don't have a voltmeter or alternator
out light), if you extend the gear with the battery PLEASE give a check of the
crank counterclockwise to confirm that you have a FULL extension and only about
1/4 turn to the mechanical stop of the transmission sector gear. When your plane
is on jacks sometime and the gear is down, give a few turns of the crank
CLOCKWISE and see how few turns it takes to break the nose gear downlock arm
from over center. You really want to make sure, via the crank, that your
weakened battery got the gear completely down.
