Quoted from eb94114:
I have recently been trying to do more work on my game and not have techs do it for me. That said, I am still learning a lot, and I am getting the message: "Check Switch 54/Lower Jet Area" on the test report with a credit dot coming up. Any direction on how to go about doing that and fixing it? Thanks in advance from a very not-technical pinsider.
If you don't have the game manual, go to ipdb.org, search game name and find the manual as pdf. On page 2-43 you will see all switches and where nr 54 is (above right outlane).
Now a switch can be flagged as "not working" by the game simply when a ball haven't hit it in a while, so depending on your rubber placement in the pop area this can be your case. Simply activate the switch by hand when game is running and see if credit dot disappear.
If this doesn't work go into the test menu, select switch test and press the 54 switch and see if the game recognizes you pressing it. If it doesn't either the switch is bad or some wiring might have come loose, either way you have to open the game and check below the playfield.
