Hey group
I was working on a solid state Mata Hari today and for some reason it keeps scoring by itself. Sometimes you can play a ball and everything is fine. Then all of a sudden, it will start scoring by itself. I looked at every switch and do not see anything wrong..
Any suggestions??
Thanks in advance!

Could be bad caps on the switches or you could have the problem I had with the drop targets. With all targets up, pound on the playfield and see if it starts scoring. If not, start dropping targets one at a time and repeat. Have you replaced the drop targets with new, by chance?

Thanks dothedoo I did not touch the drop targets. I turned the game on, started a game and the drop targets reset. The game then starts scoring by itself. Pounding on the playfield does nothing

was this a visual check or you had the machine is switch test mode

Visual check including underneath making sure they all switches were not close..

Had this problem on mine and it turned out to be the single switch behind the rubbers in back of the targets. True up on the switch test question. Run the diags and see if a stuck switch is identified.

you need to put it in switch test mode to be 100% sure & go from there
