Track and field restoration

[Sarah77]

Hi, I purchased a converted track and field. I've spent a whole week or more turning it back into a track and field using the jamma setup that it came with. The jamma 60 in 1 that I have works great, but my track and field board isn't working as should. It has lines running through it. Does anyone have any idea of what the problem might be? I was also wondering if anyone has or knows where I could get 2 coin reject buttons and the track and field cardboard shroud?.

Check you don't have voltage droop before doing anything more major. Measure at the board.

If it's a cheap Chinese JAMMA loom, it won't be good enough for original PCBs. The power and ground wires on them are a joke.

I checked the voltage as that's what I thought it could be 5.4 and I did adjust it both ways and the image was still the same. Maybe its a ground issue or something to do with the button setup. I'm a newbie so I'm easily confused

Yeah, you could be right. I just tested the track and field on a jamma setup and the screen is fine

Where would get or what would you recommend for a good harness please?

Sadly, I don't know anywhere that sells a good quality JAMMA harness. You could ask in the Wanted section incase someone has one spare. Otherwise, you can replace the power/ground wires on your one, if you're up for a bit of soldering. I think AWG 18 is the gauge of wire to use.

Would a suzo happ harness be any good? This is my first restoration and will be my first attempt at a jamma setup, but I feel confident enough as having a jamma setup already to work from is a bonus. Thank you for your help. I guess just need a little reassurance

You mean this one?

Suzo Happ Jamma Harness Wiring 150cm / 56 pins (28 pin per side)

High quality Jamma wiring with 22AWG wide wires. This cable comes without crimped terminals / end connectors for customization and user preference (Includes wiring for speakers).

Hmm, I don't know. The AWG 22 wires sound a bit weedy to me for power and ground.

Yeah, thats what I was looking at... Well at least I know it not the pcb. I will keep looking for a better harness. There's 2 ground wires cut in the cabinet but they don't lead anywhere. The harness doesn't look to bad. I probably need to do a little bit more research into jamma setup
