Hi,

I've recently bought a refurbished Twilight Zone, which has LEDs installed throughout. It has some mods attached to the playfield, but in some cases (for reasons unknown) they aren't wired in.

One such mod is a camera mod. It has a pair of red and black crocodile clips on the end of the wire, and the install instructions (https://drive.google.com/file/d/0B18V2Lyll3xhUXlBZnFOdGRvOWc/view) talk about connecting them to the camera insert. I've looked at this on the underside, and it looks like a lamp diode fitting - but I haven't got a clue where I should attach this red and black crocodile clip. I tried connecting it once already and all I managed to do was end up making multiple lamps light up erroneously at the same time (a short I guess), so have removed them again.

I should say that I'm pretty clueless about electronics beyond the fact that I know red = positive and black = negative.

Here is a photo of the "camera" lamp insert on the playfield:

..and here are the two crocodile clips that are currently attached to an inert metal bar:

Also - it has a slot machine mod (http://www.pinballdecals.com/TwilightZoneUltimateSlotMachinePage.html) which has three separate circuits for 3 different LEDs (two orange ones either side, a blue one at the top that is supposed to light up when Super Slot door panel is lit, and a third white LED that is supposed to be wired to general illumination). Only the 2 orange ones are currently working. The orange cable pair is wired into a couple of plugs...

..the blue pair is soldered directly to the Super Slot location (but doesn't come on when this panel is lit?)

..the green pair, which by process of elimination I'm guessing is the white LED and is supposed to be "wired to general illumination" is just hanging there..

Thanks in advance for any help anyone can provide

The camera mod is yours, I believe.

The problem is not so much that I can't get the mod to illuminate (white LED top, multicoloured one bottom right?), but when it is connected it causes other lamps to come on when they shouldn't. There may be others coming on by mistake too.

For example - with mod connected and on single lamp test on e.g. Super Slot, both Super Slot and The Spiral light up (not ghosting, I mean properly switched on).

I'm presuming I've just wired it wrong, since the mod works, but I don't know how to wire it to the camera insert (first image in my original post). There is a green/yellow wire going to one prong, and two red/green wires going to another side. I don't know based on this where the red/black croc clips should go.

Thanks in advance.

Ok thanks, this is what it looks like - it looked like yours from what I could tell, but as I didn't buy the mods originally I couldn't confirm.

Thanks. I'm pretty much a novice when it comes to this stuff I'm afraid.

The camera angle isn't great, but yes both red wires are connected to the same lug. I guess I need to attach the black (or red?) crocodile clip to the lug on the OTHER side? (this is the unbanded side right?)

Excellent, thanks, I'll give that a try.

The last time I wired it up I connected the clip to the same lug that the red wires are attached to, and the other clip to the green wired lug, and it behaved exactly as you stated - i.e. more than one lamp would come on during "single lamp" tests.

Just wired it up as instructed by Coyote, and now it's working like a charm with no random lights illuminating. You're an absolute star!

Thanks to everyone for your help. That's one mod sorted, now onto the next ones
