NewGin CR Furious Gaou MB 2003 - Alarm Sound Issue

[CollinP]

I've just picked up a NewGin - CR Furious Gaou MB 2003. (Images 01 and 02)


Could anyone please help me with the following points:


1) There is an alarm type sound on all of the time when powered on.


At the rear of the machine there is a wire connector at the top right. When the wires are connected the alarm sound is on, when disconnected the alarm sound goes off. If I leave the wires disconnected the game will play but there is no music. (Images 03 and 04)


There is a toggle switch (painted yellow) and there is a #7 showing on one of the boards.(Image 05).


I tried holding the toggle switch on/up before powering on and it seemed to make a difference. The alarm sound then went off when I powered up and if I then played a game the music also comes on, but so does the alarm sound. I think I'm close to solving but seem to be missing a step or two.


Is there a reset procedure for these machines?




2) I don't know if this is related to the #1 issue or any reset procedures, but on the rear, top of door and left of the tracks, there is a large plastic component with spring loaded claws. The movement of the claws operates an open/closed micro switch. It's just hanging in mid air and I can't see where it fits. (Image 06)




3) Do I need the fill the tracks at the rear (top) of the machine door with balls?

Thanks. CollinP
