I was given a Control master 20 - not sure if it works - plugged it in and only get voltage across terminals labeled for meter purposed terminals 3,4. No voltage across any other terminals - no manual and cannot find one online. I have tried different settings to same results. ANy ideas how I can proceed? New to trains and would love if this works for now.
