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.
