I have a Wells Gardner Model 25K7194 and I have a connection question that is probably pretty simple. This is my first post so please go easy on me... :)
On the WG K7194 Monitor board section where you connect the video cables there is a set of 6 pin connections (left side) and a set of 3 pins (right side). I know that from left to right they are Red, Green, Blue, Gnd, +V.Sync, +H.Sync and then the set of 3 are Gnd, -V.Sync, -H.Sync.
I purchased what was supposed to be a WG monitor cable but arrived with just the 6 pins, with the +V.Sync Yellow and the +H. Sync White.
My questions:
1. I bought a Super Jamma Plus harness which already had the wires grouped and labeled. The "Video" group has Red, Green, Blue, Black and a white wire (5wires)- What does the white wire plug into? If I matched the colors to the 6 pin monitor cable I bought it would go to the +H. Sync.
2. What are the +/- V. and H. Sychs used for? The harness that I pulled out did not use all of the pins. It had the Red, Green, Blue and Black of course, but then had a white wire going over to the far right pin, which I think is the -H.Sync. (I pulled out a custom harness that used a PlayStation as the game console and translated the controls to buttons on the CP- anyone want it? LOL!) I think knowing what the +/-V. and H. Syncs are for will help.
3. Did I buy the wrong monitor cable (just having a 6 pin connection)?
4. If I do use the monitor cable that I have, I will have one extra/unused wire if I match the wires up with the "Video" cluster in the Jamma Plus Harness.
Thank you for any help or knowledge you can share!
