many techs, myself included, have spent hours kicking the crap out of machines over this issue.

Hello I have the door open m problem in two slamtop gameking and try the solution and connect the two with an optical cable as my previous post it worked once and then gave the same problem even with the cables connected thanks for the response If this clears the M door problem you will have to chase the break in the harness. It also by passes all other switches since these are all in the ground return wire of the optics. Basically what you are doing is feeding the output pulses from the processor straight back to the optic input circuit. Unplug both optics - Now use a piece of wire to and connect the Green optic wire on the door to the Purple optic wire in the cabinet. Just checked and it works on Game King as well. This is a trick that I use on S+ and PE+. Was waiting for monitors that were sent away to confirm something. You may have to keychip it but I assume you have it available.īTW the door optics dont use the IO cards - signals go to processor board via the backplane. Sounds like a faulty processor board then - Try a known working processor board in the problem machine to confirm. It seems I am missing 5v at the optic harness with the door open. The drop door has the only jumper, OEM part #XXXX.

We have replace all with known working, and have lined up the optics. Micro switch that gets triggered by the top latch of the BV door.Īlso remove the optics and align them manually.

Have a constant M Door open on a 3902 Game King Slant.
