First..... I left my meter and leads at home. I had to use a manual ranging meter and not knowing the sensor's proper resistance, I had the meter set to 200 Ohms. With this range set, 8K Ohms is read as an open. I was seeing "two" bad loops and that just didn't make sense.

It was only after I moved the selection to 20K that I was able to get the proper readings.

I'm "not" a fan of manual ranging meters for just this reason.

I had to use safety wire as test leads at the card. I'm not big on doing this either.

A Decade Box would of been useful as a substitute for sensor resistance simulation.]]>

Two fingernails will pop the light cover off. The actual assembly is held in by two tabs that pull up to a mounting plate that butts up to the backside of the glare-shield panel. These tabs are loosened to the point of swinging back into the switch with two allen head screws.

With the switch removed, the sleeve can be seen. On the rear side of the sleeve, there are two cut out slots that the tabs engage and pull up to for securing the switch assembly.

The switch is held into the socket by two bent tabs. One can be (barely) seen in this image above. A awl or pocket screwdriver will bend these up quite easily.

Switch removed and socket visible.

The sleeve has nothing to back it up when inserting the switch assembly. On this aircraft, removal of the co-pilot's navigation control panel allowed for holding the sleeve in place while the allen screws/tabs are tightened down. (This was rather lucky...... the initial thought was that the glare shield cover was going to need to be pulled up.) It is best practice to screw the tabs as far back as possible before sliding the sleeve over. If they are to far forward they could actually be beyond the sleeve cut out and they will not have anything to catch.

New switch in. Controller out. After a re-install of the controller, it needs a functional check just to be sure all functions operate normal.]]>
