Xenophobe Joystick Wiring
(1/3) > >>
coasternuts:
I have a Xenophobe joystick, with trigger and two lighted buttons.  There are 4 wires coming from the handle, black, brown, blue, yellow.  I wanted to make sure the switches were working so I set up a continuity tester between the black(assumed gnd) and the others.  I got the trigger to signal, but not the two lighted ones.   Two questions,  how much voltage do I send through to test the lights, and do I need that voltage to register a "fire" in the top mounted handle?

Thanks

Bump.

 I suppose I could try sending 3,5, or 12 volts through each of the two wires I know must be the top fires but I'm ignorant enough about electronics to know if I need AC or DC?  (I assume DC.)

I just want to be able to get them lighted and registering fires.  The switches sound and feel fine.  Just no continuity on contact.

 Any help??

I have a Xenophobe joystick I bought on Ebay a few years ago (Still hoping to find the day that I get to use it) and I have never investigated so I tried just now.

On mine, yellow is the common wire and when I do continuity with yellow and each of the other 3, I get all 3 buttons to work.

 I do see a higher resistance on the thumbs, the trigger is straight shorted.  I wonder if that's a coincidence, maybe the contacts need cleaning (wish I had the bit to unscrew that handle, whatever it is).

Since there's no extra wires to light any lights, are you sure they were lighted buttons? I can't remember how it looked back in the 80s when I played it.  I found a link to a schematic and also there's no mention of lights, but it does confirm the yellow ground and the colors of the other button wires.  Look at sheet 2-2 on the right side you'l see joystick connector info.

Whoo hoo!! That was it!  Yellow is common?  I didn't think to try that.  Thanks Druin.  My only concerns now is if the leds still even work, if that's what's even in there and how would I get into it to change it.

This screws might prove problematic.   :P

See my post again, I just edited it...

No luck on lights, and I have the same handle problem.
