Hi Just bringing a Gottlieb Hot Shot back to life hadn't been on for years, I solved the continuos score motor issue, by R&R the reels. I now have an issue where the lights do not work at all on the playfield GI might but the playfield lights for the balls and others do not work at all. Also the 10's 100's and 1000's switches do nothing no noise no nothing the 500 and others do score.

Any pointers on where to start with either issue would be great, the machine was just moved so I will double check the harness plug I read somewhere that could be the scoring issue with the 10~1000's.

Thanks for any ideas, I just ordered schematics, this is my first EM work, I am very comfortable and skilled on SS machines, but this is a whole new path for me.

Thank you for your thoughts, I am awaiting schematics right now. I'll sand and re-seat the connectors first

Out of curiuousity, is H part of the tilt unit? That was the one thing I thought might be causing the light issues as iirc when the game tilts the playfield goes dark completely.
