We can test diseqc switches using a 9 volt battery and a Digital Meter.
Just connect the battery positive pole to the center of the coaxial cable and negative will be
connected to the shield of the cable.

Looking at the Digital Meter you can test the 4 input ports of the switch, each port should be about .8 to 1.2 volts less than the battery voltage, any port less than 1.5 volts than the battery voltage is a bad port.

Test 1
Port#1: 8.2V
Port#2: 8.23V
Port#3: 8.15V
Port#4: 8.24V
All the port are in good condition.

Test 2
Port#1: 8.2V
Port#2: 6.23V
Port#3: 8.15V
Port#4: 8.24V
Port #2: Bad Port
