    Default Nishijin Mad Monster fever bugs

    I recently picked up this machine along with a Monroe in the same style frame as part of a package deal, this one however has some odd problems that arenít reproducible all the time:

    1. Getting a scoring ball in the 1 or 2 pockets sometimes IMMEDIATLY triggers a fever round; a V is shown on the led display; the flippers/arms open once then it goes into alarm/error mode and then requires a reboot as it sounds like an ambulance. (This shouldnít happen).

    However most of the time they function normally and just open the flippers like they are supposed to giving the opportunity to get a fever via the V hole in the center feature like every other hanemono of this vintage.

    2. Sometime during a fever it will suddenly go into error mode for no reason; balls are being fired and making it into the center feature past the arms/flippers (Iím not a hanemono newb ) and the machine is full of balls; no overflow happening, etc.

    All payouts and everything else work just fine; this machine has vintage payout mechanics so it pays out just fine even without electricity. Any ideas? Iím thinking must be something in the mystery metal box of obsolete electronic components that might be going out.

    Is the centre feature counting the V pocket hits correctly?
    All the Hanamonos I've had, had a 7 seg display that would count the hits per round. As you say It pays out without power. maybe the pocket sensor is playing up?

    I donít think so, it kept prematurely ending, then starting the next fever round before I could get 10 balls in.


    Normally it should allow you 20 seconds or so to score either 9 or 10 balls per round.

    Today itís acting up really bad; going into Fever mode then immediately errors out (with alarm) as soon as a ball is dropped in the 1 pocket.

    Itís pretty odd. Yesterday it was somewhat playable; today not so much.

    I figured it out! I guess a connector wasnít fully seated on the boards that was possibly bumped in transit or just a corrosion issue/bad connection (this machine must have been stored somewhere damp at one point, there was a lot of nail corrosion and chrome rust in spots) I kinda feel dumb for not completely removing and replugging in each one! (before I just checked they were all connected/seated, so figured I better double check my work). Maybe the cats did it.. who knows.

    These are the old style connectors that seem quite brittle so was being lazy as I didnít want to break one.

    Anyhow, the Mad Monster is functioning 100% like new!

    I polished the nails up to get it in tip top shape:
