Thank you for your suggestions. I haven't had a chance as yet. I think the manual is incorrect in that it state f105 for the bank of solenoids but I found f104 was the offender. My thoughts as to what may be causing the problem could be the side magna save magnets. Either or both may be too sensitive and are being activating a lot during game play. So this may be putting too much strain on the fuse. I will try adjusting these first unless someone can suggest more obvious things to look at first. Thanks again
