# Ring Magnet Blues #

Got those low-down # Ring Magnet Blues # today.


Ring isn't holding the ball anymore, didn't notice it right away.
Had worked OK for a day or two so:
  • Checked over the switches and optos associated with the ring. There is a special Ring Test (sounds painful, doesn't it?)
  • Spinner #52 not stuck and only makes when it should.  All switches are showing as normal during the ring tests.
  • Optos at #47 and trough exit #48 are fine.  I'm pretty good with this stuff, and everything looks good to me!
  • Magnet will do a "hold and drop" with a 4A SB (slo-blo) fuse, but "grab and throw" will blow the fuse.
    That's where it throws the ball behind the ring and out the wireform.  It needs to be able to do this!
  • To get "grab and throw" to work at all, need install a 5A SB , or a mini-circuit breaker rated at 5A.
     It definitely blows a 4A SB or 5A Fast-blo fuse when the game tries to "grab and throw" the ball.
Today was not a good pinball day.     :(
