Hey guys - my Shadow's had this weird issue for a while now. The sanctum target goes up/down/up/down ...as if it's "confused"...and eventually will just stay down. Keep in mind this isn't a normal drop target so it's not an issue of catching on the lip. The coil/peg that holds the target up is firing to drop the target.
I've completely gone over the mech. Totally cleaned it, installed new coils & switch. Everything checks out in test. The optos in front of the target also check out fine in test. Even so - it still does the weird up/down/up/down behavior.
What am I missing here? I'm thinking I might have a switch matrix board issue at this point...but thought I'd ask in case I'm missing something obvious.
Thanks!
