Quoted from chuckwurt:
Try the zconnector like some one else suggested. If that’s making a poor connection I guess that could cause issues too. But to me it sounds like switch adjustment.
If I remember right, this is a normally closed switch so when you hit the WW, it opens and registers the hit. Pop the hood and see if when the WW is at rest, it’s barely pushing the switch closed.
Put the game in switch test while you’re doing this. If every little vibration is opening that switch, it could be your issue.
is it possible it was just the code I was using? Because I updated from Cleland old version to the official stern version and I think things are ok so far (crossing my fingers!)
