Got a Shocker RSX, been fine all season and over this last 2 months has began indicating low battery on every fresh 9v I try and giving an intermittent eye fault. I've stripped the gun, cleaned everything, reseated , etc. and the fault remains. The gun itself still shoots absolutely fine with the eyes off and sometimes with eyes on. But the fault is really niggling me. Any ideas as to what the problem may be? I have a feeling it may be a board fault but thought I'd put the question out encase I'm missing anything obvious and someone else has had the same issue. Cheers!
