I'm limited in my electronic knowledge. But I do understand most trouble shooting information. On my game the drop targets on the left side when hit don't advance the bonus value, the ones on the right work. What should I look for in the wiring?

Any help would be very much appreciated.

Hi Scott,

Probably the easiest way to explain it when you have something that is
not working is to first find that item on the schematic.

In most cases one side of the activating coil will go to the 'Hot' side
of the solenoid power, the other side goes into a bit of a maze of representational wires and switches down to the Common. Common typically
runs down the middle of the schematic - lengthwise.

Now you study the side that appears to work - in this case the right
side drop target switches that advance the Advance Bonus Unit Step-Up
coil, that will be the coil name. See if you can follow that and find
out where the left side drop target switches appear.

(Of course, before all this, I am assuming you already checked for a
broken wire at the left side drop target switch assembly and visually comparing to the right side!)

Next try to figure out where breaks or bad connections would stop the
left side switches from performing the same as the right side - for
example, if there is an Alternating Relay or some such set of switches
that separates the action of the right side from the left.

That is about all I can help you with right now, pity there won't be a
pinball show in June for the PNW assoc, I was hoping to go back and do
part 2 of Reading Schematics - Trouble Shooting Processes.

However between Covid-19 and a different minor medical problem for me,
that just isn't going to happen this year.

Stay healthy!

It looks like "Out of Sight" might be similar to "Spirit of 76" that I
have schematics for.

On the schematics, find the ADD BONUS coil and trace the circuit to the
right. You should find a switch that adds the bonus. On So76 it's D.
Next find the coil for that relay. Trace right from that coil to find switches that add bonus.

On So76 all the drop target switches are wired in parallel. They are momentary switches that activate when the drop target falls. If Out of
Sight is the same it indicates something common to all of the switches
like a broken wire as John pointed out. It could also be something
mechanical interfering with switch operation.

If you would like more help understanding the operation snap a picture
of those two sections of the schematic and email them to kcimming at pobox.com.
