Police force issue

[Steevsee]

The opto board with wires going in and coming out again. 
One side leads to the other opto, where does the other side go?

Just connects to other set of wires.
Here is pic of spare playfield. Hope it helps

Do you mean the wire colour changes?

[infinite1977]

I can't follow it all the way

[Steevsee]

What about on the spare play field, if you cut some cable ties?

[infinite1977]

Will give it a go. So am I following from the middle drop down target or the other one

[infinite1977]

So both connect to each other then go to another joiner then connect all the way to J19 . On my pin then there is a 2 pin plug that goes to J2. I can only assume there should be another for J16

[infinite1977]

I really need someone with this pin to take a pic to see if we can create a joiner from J2 to j16

[Steevsee]

J2 should connect to 3J1(Power supply) positions 5 and 13.

There should be no room at 2J19 for any extra wires.  If you have Black/yellow and Grey/yellow wires at J19, something is very wrong.

[infinite1977]

I don't have them at 19. The wires on the spare playfield just come off as all the harness is not there. The connection for J2 are the same for J16.  That being said i did try taking the connection from J2 and put it on J16 but the drop targets did not work

[Steevsee]

One possible solution I can think of, is to remove the connectors from both optos along with what ever wire is still attached (Blk/Yel, Gry/Yel wires only!) from the rest of the playfield harness, post it to me and I should be able to add a connector for 2J16.  Just to make sure it will be long enough I can add extra length.

Edit
To save on postage, take a photo of what's left of the existing harness once removed.  Probably won't need it all.

[infinite1977]

Not sure that would be practical. I appreciate the offer. Can i not spit it from the J2 connector as it is the same connector. ?

[Steevsee]

Technically you could bypass the interconnect board and run the optos directly from J2.  Not sure if any fusing or resistance occurs on the board that would be of concern, without consulting schematics.

You'll also still need to find the feed wires to hookup to J2.

Most people would consider it a hack though.

For testing purposes you could hook up J2 with test leads and find a suitable place to input the voltage along the black-yellow/grey- yellow wires going to the optos.

Also please see my edit in previous post if you haven't already.

Not sure that would be practical...(snip)

Wonder if you have misunderstood me?  Can't see why my suggestion would be even slightly impractical?

I think i may have confused myself and the situation

[infinite1977]

Ok let's reset as i am getting things muddled.

The wires from the opto under the playfield go to a joiner and then two wires go to J16 (i currently had this plugged into J2)
So if i plug it into J16 this means J2 is now blank so i need to get two wires into J2

[Steevsee]

J2 should connect to 3J1(Power supply) positions 5 and 13.

Ain't this detective work fun!
