So, after a long ass haul I got my Defender all up and running great with a Jrok card. The monitor was dialed in. Rebuilt the controls. It was really coming along. The coin door was the last real issue. The wiring was butchered and nothing worked. So I figured I'd go for the easy fix and re-do the coin eject lights first. Had a beer and built a harness. Had another beer and hooked everything up. Turned it on. Zaps and sparking noises.
I had put the ground to the +6 volts and vice versa. So I ran juice through the earth ground on the game.
I unhooked my dumb shit light job and turned the game back on. Crazy wazy lines in the screen. I have over the last 3 months done the following to diagnose where my issue is without any change:
1. Put a new chassis into the game.
2. Bypassed all of the switches (on/off and door open killers)
3. Completely taken the coin door out of the loop.
4. Rebuilt the power supply stuff (filter, blocks, fuses and transformer) Literally everything including the wiring.
5. Swapped in a new switching power supply.
6. Pulled out the Jrok card and stuck it in another cab where it works fine.
7. Put another Jrok into Defender where it displayed the same issue.
Here are two images of what it's doing. The band of waviness just slowly loops from top to bottom over and over and the details look crappy. (The ship looks like it's missing a few pixels)
Does anyone have any ideas where I can check next? I'm solidly out of ideas.
Thanks as always for taking the time to help.
