I'll need to see a high quality scan of the schematic from (for example) Staples ($2) or Kinkos ($6)

I'm so sorry, I do not have the schematics. Tried looking for them online but to no avail.

Check switches on the lock relay. Might be called hold relay.

pbresource.com or marcospecialties.com may have it. Did you try them?

Also, the other owners may have it.

There are schematics for Trade Winds and other games made around the same time on ipdb.org. The Trade Winds schematic shows that the backbox and playfield have separate fuses.

If your game has the same configuration you could have a bad 6V playfield fuse, or a bad fuse holder.

check for loose or broken connections at the jones plugs.

Hi, I checked the fuses and the fuse holder, seems good. Also looked at he switches on the lock relay, that also seems to check out. All the jones plugs have good continuity, no apparent loose connections there. Still no lights.

Trade Winds, Reserve and possibly other games from this era put many of the playfield lights through a Make/Break switch on the Tilt relay:

In Trade Winds the wire colors are 51/white-red, 50/white and 95/gray-white. Do you have a similar switch?

Hi all, I got my problem fixed, turns out it was a bad solder joint on the fuse block. It all works fine now, thank you all for your help.
