Ed, that is a worthwhile suggestion. I am going to pick up some resistors tomorrow. I note that the sensors are 10 to 180 ohms for temp and pressure, was there a reason for the suggestion of 20K?

Thanks.

Just a WAG, Bill.  Could it be the oscillator of the microchip in the EM2 generating the nose because some of the pins (tied to the sensors) are not a complete circuit. Might try just hooking up some 20K ohm resistors between your sensor leads and ground just to see.  Either that or perhaps getting feed back from the chip on your power lines suggesting a low value .01uf capacitor.

I am in the process of wiring up and testing each piece of electronic equipment before putting the top on my plane which will make it much harder to get access.

I have an SL-30 NAV/COM and SL-40 COM. The COM works, but when I turn on the EM-2 I get a bunch of hash (white noise).  Any suggestions on diagonstics? The EM-2 is not connected to 'all' sensors yet.
