I recently bought a Mata Hari with an Alltek board. I have been going over it to make sure everything works and here is what I am experiencing.
1) All switches register and score as expected except when any right drop target is down
2) Using the left outlane switch, when the top right drop target is down everything appears to be fine
3) Using the left outlane switch, when the second from top right drop target is down, the right sling fires
4) Using the left outlane switch, when the third from top right drop target is down, the left sling fires
5) Using the left outlane switch, when the bottom right drop target is down, all pop bumpers fire
Since I am leaving each drop target down, items 3 -5 are happening simultaneously. I have reviewed the schematics and it appears that somehow the ST4 column is shorted by the right drop targets. I am at a loss as to how to fix this issue.
Help...please!
Thanks,
Dave
