[Amps] using a scope to time relays

[Steve Flood]

I'm attempting to set my input and output relay sequencing using a scope.  I am using a 9v battery source to provide the indication of contact closure.  How do you get the scope to show the actual sudden voltage change as contact closure occurs? My traces simply move up and down as I close the amp key line.  I get the impression this is a common way to set up the relays but what am I missing here?
