K7000 Monitor Blowing Fuses (19K7901)
I picked up a Final Fight jamma cab which was working but had an intermittently working monitor. Sometimes it played blind, sometimes it came up with video. It had neck glow and I could turn up the brightness and see white on the screen. I also picked up a SF2 cab that had a completely black monitor that also played blind.
My friend and I replaced the flyback transformers and capped the monitor boards for both cabs last night. When I hooked it up it looked the same. Then after turning it on and of a few times the main fuse blew. I installed a new fuse and it blew that one, then I removed power to everything except the monitor and it powers up fine.
The monitor is a Wells Gardner 19K7901.
I installed a K7000 series cap kit and flyback I bought from twistedquarter.com.
The fuse on the video board is not blown. I have double checked cap polarities and looked for burn marks but didn't see any. What should I check next?
Another question, there is a green ground line running up to the coin door that has two more grounding forks connected to it that aren't connected to anything. I thought one should be connected to the video chassis since its not grounded anywhere else so I've had it connected there since I started on the cab. Where should those two extra points be screwed down? Control panel and video chassis?
