hey guys

I am getting an error with the hi/low alarm, every 15 minutes or so of play.

the lights dim down to just a few of the pockets blinking and the center goes dark.

if I unplug to reset (didn't see a reset button on this one), it plays fine.

wondering if there's a bad or dirty sensor somewhere? there hasn't been a ball jam when this happened (at least since when I first got it with jackpotting too much due to pulled nails).

anyone else had this problem on this type nishijin? it's sort of a C with motors and solenoids.
