I’m not suggesting that any of the following applies to your current problem but it may help illustrate how you can end up with a perplexing problem with your trigger circuit.

1. Somehow I ended up with stock of some ICS wiring harnesses. I’ve never seen an ICS anything in my shop. One day I installed one in a version 2 gearbox and then drove myself crazy until I noticed that the metal part of the switch that moves back and forth when you pull the trigger is much shorter than any other brand trigger I have ever seen. Thus it barely makes connection if at all. Replaced with different brand wiring harness and all is well.

2. Tried using a trigger that came from a cheap Cybergun gearbox in a Modify Torus gearbox for a custom build. After many hours of banging my head on the work bench trying to understand why sometimes it would fire and other times it wouldn’t I came to understand the engagement of the trigger with the switch was paper thin and the trigger would pass beyond the switch and end up in front of the switch so next time I tried to pull the trigger the switch did not move forward. Changed out trigger for a Mad Bull M16 trigger and all is well with the world.

3. Trigger arching can add so much corrosion to the contracts that they become high resistance and don’t allow the current to flow but this should not be a problem with a new switch.
