Title: Alpha-open door M ???
Post by: slots-4-u on April 29, 2014, 09:37:52 AM

I'm missing something but can't put my finger on it. On Alpha 9000 have open door M. Checked switches on all doors & seem Ok. Put other switches in and no difference. When open door no buzzer goes off. What am I missing.
Thanks Ford

Just pull off the cherry switches and splice the top box and middle door switches so they are by-passed.  Now you are down to one door switch...bottom door. 


Still have the error?  Try a new switch. 


Still have the error?  Start checking harnesses from all 3 doors back to the back plane looking for a break in the line.


No breaks found?  Try a new board.


Still have the error?  Try a new back plane.


Still have the error?  Throw machine off a cliff.

Thanks Jim. Will try all you said except for throwing off cliff.
@ switches all I do is join wires?

Your the man Jim. Eliminated top 2 switches needed new switch on bottom.
Thanks Ford
