I'm new to this forum, and have read a lot of great posts that I found helpful...I thought I'd see if someone could give me an assist with my Williams Gulfstream. I've gotten a number of errors sorted out on this machine, one by reading a post here, but there is one remaining I can't seem to find. I am at a disadvantage since I have no paperwork on this machine. The center target is not scoring when hit. I've checked things and discovered the following: When the center target is hit, it does activate the center target relay. The relay stays energized until the next time the score motor runs by hitting something else, say the 500 point roll over, and then scores the center target points. It seems when the center target relay activates, it should start the score motor, but it does not. I could be wrong though...any ideas? I'm almost done with the playfield as well, just a few parts left to clean up...attached a pic for your review.

Thanks for any assistance...

Thanks for the tips guys...I have tried to cross pairs of connectors on that relay, but none that I could find that start the score motor. I thought too, it might be a problem in the wire that runs to the score motor...looks like I'll have to try to find a schematic for this machine.

Chrisbee, thanks so much for this feedback, yes, I've narrowed this to the orange wire I believe...I will look closer tonight though at this. I just ordered a schematic from Steve Young this morning...I can usually sort them out without paperwork, but looks like it will be very helpful in this case. This forum is great, lot's of great feedback and knowledge!

I've ordered a schematic for this machine, should be here today...if I get stuck after that arrives, I'll add to this post...maybe it will help someone else as well. Thanks for all the assistance...more to come.

Problem Solved - I got the schematic, and it confirmed the line I thought (orange) was the line that starts the score motor. I also noticed in the schematic, this same circuit is shared by a number of relays...so instead if unspooling the harness to find the problem in that line, I ran a jumper to a neighboring relay on that same circuit to the score motor, because I knew that connection was working. The machine is working nicely now, and that saved countless hours trying to hunt down the problem in that line. This is a fast machine, we've decided to keep this one in our arcade. The play field turned out nice, pops are rebuilt, sounds great...pretty challenging.
