HI Guys.

I mentioned I had a problem with the motor running the Belle... I have located the problem further up and need your advice now.

The relay before the motor is bad. That is the one making the rattling noise and subsequently let´s uneven power through to the motor. Thus the motor and gears rattle and shake. This happens only in attract mode. In attract mode the motor is supposed to be off. However the relay, weak as it is (due to time probably ?), cannot resist and hold back the voltage but it leaks through..

If i change the relay would that do it or wold there still be a problem higher up in the flow ? If my math is right there is constant voltage to the relay. Why put a relay inbetween and not have the motor CPU controlled and shut power off when the game is in attract mode ? Could the game be putting out higher voltage than the relay can handle ? If so, could there be a bad transistor involved further up ?

Thanks for any advice if I´m on the right track.

The game acts fine untill warmed up (first 8-15minutes).. That would still support the theory with a bad solder joint cracking up. Throw in the occuring dead DMD phenomena while it happens and it´s beyond my reason.... At least at this point.

HI. No, I didn´t get around to it yet. Am busy with my Getaway but need to start making a plan how to conquer the relay problem on Maverick...

I checked mine... I have the upgrade installed by the previous owner... It does NOT work very good.. Apparently the magnet is only ziptied on the leftside through the hole... As soon as the VUK on the right gets into business the magnet moves ever so little but it is still enough to hinder the ball and interupt the Lauren Belle ball count.

Has anyone figured this out yet...? I have yet to fully check thoroughly what is going on but I can almost say that the magnet needs to be secured on also the right side in order to stay put... Is this at all possible?

Thanks
Matt
