Quoted from pinden007:
Revisiting my drop target issues/errors.
In switch test mode they seem to function fine mechanically. However, when target 1 and 2 drop they don't register as dropped. Target 3 does regisiter. Also, i do get all 3 opti alerts for all three balls. Target 3 registers up and down.
So there seems to be an issue with target 1 and 2 drops which is the errors I'm getting.
If it's not mechanical (springs,etc), how do I fix this?
I think I found the culprit. The little button is not registering on 1 and 2 but works perfect on 3. Do I need 2 new parts? See picture. It completely doesn't work on target 1, on target 2 it works about 20% of the time.
For everyone getting drop target errors check the switches/buttons.
EDIT: #2 with a meter reading all three buttons seem to register the same as in when the button is depressed it registers a change on the meter reading. So now I don't know if the issue lies in the button/switch or in a board somewhere else. The plug this firmly in the board.
Sorry I an a newbie when it comes to repairs.
I had drop target 1 down error last night.
I removed all the balls.
I lifted the playfield up to the backbox( I usually put a towel or something across the top of the edge of the backbox)
I turned the machine on and went into switch test mode in the menu.
Now any switch I make, makes a noise and the screen tells you what switch was made.
Carefully push that drop darget 1 switch down with your finger, if the switch is ok it will make the noise.
You can check the others too.
Now does the switch make when the drop target drops?
With your finger on the top of the playfield push the drop target down.
Does it make a noise?
Mine did not make the noise.
You can push the target back up by pushing the rod in the coil up and back.
Now on your pic you see the two nuts holding the switch, one has a slot in it.
You can loosen the two nuts and adjust the switch to make when the drop target is down.
The slot is there to give you some adjustment on all the switches in the drops.(good thinking Scott)
I hope I have explained this easy for you to understand.
