The middle target in the 5-bank drop target works intermittently and then quits, so the bank stops resetting properly.
Five-bank drop target stops resetting reliably: clean the targets and opto
Cause: The target was hanging up in its guides and the opto was dirty, so the game did not reliably see it drop or reset.
Checks
- Push each target down and let the bank reset by hand: every target should drop and come back up crisply.
- Look for dirt and wear on the target blades and guides, and dust on the opto emitters and receivers.
- Check the opto board connector for heat damage while it is out.
Fix
- Clean the target blades and guides so each moves freely, and clean the optos, then reassemble.
