Hey guys,

I've got a board called Caveman Ninja, and it doesn't run in my Cabinet. My JAMMA harness is only connected on pin 5, but not on E, so a game that uses -5VDC wouldn't run with my current JAMMA harness, is that correct?

PS: Pins 7 8 9 11 15 on the harness and the corresponding letter side don't have any cables connected to them either. Is that normal?

Sorry about the newbie question and thanks for any answers!

If you have a -5 wire connected to pin 5 already, check to see if 5 and E are connected on the board. Try a continuity check between the two. You may find they're connected, so you won't need a wire on E.

As for the other empty spots, check this to see what may be there. Some spots will be empty normally. And if you don't have coin counters or stereo sound, you won't need wiring for those things...
 
Hey, thanks a lot for your response. I've done a continuity check on the board and 5 and E are connected. So I guess it should work then? Well seems like I'll have to take a closer look at the board to check for faults.

Thanks again!
