I've learned a great deal here over the last year, thanks to many that have helped.

I've got a 1990 Vegas whose drop targets are not all functioning. In self-test mode, targets 2 and 3 work, but not 1, 4 or 5. Contacts show electrically closed when the target is dropped, but self-test does not detect. Based on an earlier thread describing an intermittent issue with a system 1 Genie (#200329), I checked all diodes in both diode boards and found no issues.

Anyone had similar issue or can help guide me where to look next?
