On the topic of switch guards, I was very surprised at the extremely scant availability. I found the .5 inch one mentioned abundantly, however any other types were just seemingly unavailable. i found
one I did like but the only manufacturer stated contact their venders, and then when i told them none of their venders had any, and they even verified this, they said they would make me a deal if i ordered only 250 and pay tooling
cost....thanks but no.
What I wanted was the ability to secure standard .5 inch toggle switches on during flight since some of my toggles being on is mission critical, like my primary batt and primary fuel pump. I currently have the previously
mentioned guard installed upside down on my primary batt so as to have the switch activated when the guard is closed. while it works as desired in this application, it is big and kinda ugly. seems I remember spring bars that would
hold a row of toggles in one position back in my days of youth, perhaps in twins, but this point I have had no joy in finding a more elegant solution for these pesky little toggles that if bumped make my engine quiet. I do have the old
NASA style half circle guards on each side of the toggles, just not effective enough.
Any ideas from the collective?

Good idea, but afraid that source won't work - that particular guard is designed for 1/2" dia standard toggle switches - the one on the EC2/3 control panel is smaller.

Maybe it would be a good idea to put a switch guard on the cold start switch. I put a guard on after my engine started bogging and I saw that I had inadvertantly brushed againt the cold start switch while adjusting the mixture. My guard is just a piece
of stainless sheet bent into a U shape that makes it hard it inadvertantly flip it.

Especially, considering that mpja.com is practically giving them away!!

(they have several other colors, but yellow would be appropriate.)

My own experience is that when the cold start switch is inappropriately selected and the engine is running at medium-hight rpm - is that the engine does not stop immediately, but starts to bog down, sloppy sounding exhaust and then
eventually dies. But, then I am using 460 cc/min injectors. I even found that I could fly (keep engine running) with the cold start on provided I put the manual mixture control maximum lean and it was still sloppy sounding - if I had 550 cc/min injectors
I doubt that it would have kept running.
My best SWAG given that Tracy found no fault and the sudden termination of the engine - is either CAS problem or ignition (and it would have to be an ignition problem that would taken out both sets of spark producing devices). If CAS
then that could account for the sudden stoppage more so than a misplaced cold start switch in my opinion, but then distant diagnostics is still an evolving "Art". {:>)

Man, I hate that cold start switch ;-)

Thought the group would like to hear what i found when I Finally had a chance to closely examine Bill's EC2. I was hoping to find a definitive reason behind his sudden and complete loss of power on takeoff on his last flight.
On powering it up on the bench I found both A and B controllers Working normally. Bill noted in his report that in the 'Fly The Plane' situation called for in a power failure during takeoff he had not tried switching to controller B. It does not appear
that it would have done any good this time.
None of the parameters were set outside the expected range so no sign of data corruption. In fact the only thing notable about the data downloaded from it was the unusually smooth programming of the MAP table. Most of the time I find units returned for updates
with choppy looking data in the table indicating a lack of care or proper methodology in setting it up. A and B controllers had identical data.
The PCM was also returned with the unit so just in case the control panel was the cause I substituted it for the bench test panel I normally use. Thought I saw a problem because the injection pulse width was so large that it could well have caused engine
flooding. This was caused by the mixture control being set fairly high and the cold start switch being in the on position. This does not prove anything because that could easily have happened during removal of the panel from the plane or while packing it
for shipping. When the switch and mixture control was returned to normal settings the injection pulse width returned to normal.
Ran the unit on the bench for several hours while heating and subjecting it to vibration but nothing else turned up.
