Rented a C172SP (Made in 1999) on 04/10/04 and was told to start the
engine
with the battery side of the master switch only on, then turn on the
alternator side after the engine was running. I was told that this was a
new recommendation for all C172SP's. Can someone tell me where to find
the
text of this recommendation?

Thanks in advance,

This was a service bulletin that applies to Cessna piston singles having to
do with the alternator field breaker popping. Until this SB is fully
complied with you are supposed to start the engine this way. The SB came
with a temporary yellow page that is inserted into the "Normal Procedures"
checklist in the POH, but no revision for the separate checklist.

Mike Pickett tells me that you should only use the battery side of the
switch anyway, especially when using external power. He says starting the
engine on external power with the alternator switch on was what caused my
alternator to burn out several months ago.
