How to Test for Continuity with a Multimeter
To start, remove the reference cell from the probe.
1. From where the reference cell screws into the probe, to the black banana jack, should be a short.
2. To test the trigger cable, as seen on the diagram below, pins 1 and 3 should be open. Press the red trigger button (if equipped) and it should change to a short.
3. Check for shorts to ground. None of the following checks should yield a short, they should all be open. Place one lead on the metal tube (lower section) and probe the black banana jack and pins 1 and 3 on the trigger cable.
