Stormy=2C
Thanks for sharing your mystery solving skills with us.
I guess better a CHT wire than a Mag wire.......or something else.
I'm chasing down a EI fuel gauge=2C right tank=2C intermittent off /on read
ing on my capacitance system now. Tank good=2C converter good=2C unit sent
back to EI for checkout=2C next thing is to change factory wiring harness!!
Big PITA.
Larry=2C
Thanks for explaining the "let me google that for you" very cool. I never k
new that !

"Here. Let me Google that for you..."
Answered my own question with a trip to the GRT website - they sell replace
ment screw-in bayonet probe adapters for 5 bucks. I'll be good to go when
the mail runs later this week.

Cause of my recent low (190-210*F) CHT's on #4 cylinder=2C with normal pre-
start readings and normal EGT's and power in flight=2C was just what one mi
ght suspect before even pulling the cowl - a faulty sensor=3B in this case
=2C dangling free of the cylinder head=2C leaning against the intake manifo
ld tube.
What's curious is how the twist and lock spring-loaded connector came loose
on this bayonet probe: the tiny spot-welded pin that protrudes radially fr
om the side of stainless barrel that screws into the cylinder head=2C which
the probe cap is slotted to lock upon=2C fell out of its hole. I will fin
d out soon if I need to buy a whole new sensor or just the mounting assembl
y. These probes are 12 years old and have 750 hours on them. I see no way
to anticipate or detect this kind of failure before it happens. Fortunatel
y=2C it's not a big safety-of-flight item to suddenly get a low CHT reading
if the engine is still making normal power.
Off to call GRT and see what's available in the way of spare parts...

Bob - don't you hate electrical gremlins? They're the worst sort.
Almost done with my annual... new strobe head for the belly, replace a worn
alternator mounting bolt, lash up the FWF wiring with fresh zip-ties, repair
bottom damage to a wheel pant (I hate fiberglass work!) and repack the wheel
bearings... and we're GTG.
OUR FLY-IN IS ON FOR JUNE 26th!
