Hello, I have an issue with the Borg Lock drop target not successfully resetting. It looks like a pretty complex assembly to work on. Symptoms: target does reset when new ball launched but then the reset solenoid fires several times in a row unsuccessfully try to reset the target. I'm wondering if there is a FAQ or tips to troubleshoot /re and re this particular assembly - it looks a bit daunting. From what I can tell there is too much play in the coil assembly and friction along the entire system, so a through disassembly is required. Is this a common area for maintenance , like cannon harness, optos?? Thanks!
