Quoted from Redketchup:Look like i found my problem...
[quoted image]
If i isolate the droptarget actuator from the switch.... the problem go away...
Look like my drop target switch didn’t like the bath they take in the ultrasonic cleaner
It’s exactly the same problem i had with my drop target #2
did the plating come off in the bath?
guess I'll know not to do that when/if I ever get a cleaner.
Quoted from Redketchup:I Will remove and change the switch tommorow, i Will look carefully... but it’s the first Time i have this problem
might of been worn down from the actuator. maybe ground in dirt kept it from shorting on the bank, and the cleaner took that insulator away.
Quoted from cottonm4:The only thing that makes any sense here is that something happened to fiche/isolation paper. Everything else is metal-to-metal.
EDIT: And what I just said does not make any sense, either. You had the switches activated but blocked from the actuator with tape and problem stops. ????
yeah I know it's weird, not something I would of thought of either.
I think it has to do with signal resistance going to the cpu board. if it's to high of a resistance then it the signal won't act as closed.
I was playing around with a spinner switch, and even thought it was touching it only worked when the two copper parts were touching. not the plated parts.
Remember a long time ago I tried installing a tungsten EOS in a new stern, and it didn't work. Mainly tried to do a quick fix, since I didn't have an normal EOS at the time.
Quoted from Redketchup:Confirm succes!
I change the switch an everything back to normal! Yeah! Plating look ok, maybe the isolation paper or something else
Awesome, lets just chalk it up to gremlins.
