Quoted from Yelobird:
Assuming a week or so means your traveling so..... If you wish to send me Both boards this time I will reflow All pins and send it back again. Your call trying anything to help you out. Would honestly take me 10 minutes and could return same day they arrive. Just let me know and consider it done. I honestly think you have an issue with the pins on the board of possibly one of the wires in the molex has a loose grip pin. Most times while in test if you simple move the molex plug side to side and up and down you will loose signal showing the bad pin.
Long update and new troubleshooting notes:
1. I (again) switched the motor relay boards on the spinning disc and the ship motor. BOTH relay boards work the disc very reliably. I hate to go against LTG, but this in my mind completely rules out a bad motor relay board and the need to reflow pins on either board.
2. When I jumper 12V from the spinning disc and put the the game into coil test mode for the disc I can get the ship motor to work. HOWEVER - and this is likely very important - I only get it to work if I directly jumper the wires to some exposed areas on the motor posts. (see photo). Both the 12V and the ground posts for the motor have areas in the rubber sleeves that are all chewed up (don't know why). If I jumper to the 2-pin molex that leads to the motor the motor does not work even though I confirmed 12V IS at the molex connector. This makes me think I might have a bad connection at the motor itself - perhaps a broken wire at the post? I have never messed with any motor but am leaning towards uninstalling the motor and seeing if I can remove the wires at the motor and make a better connection. When doing this, is there anything I need to be mindful of so I don't screw something up? (Is this connection something slips off or would this be a soldered connection? I don't want to accidentally yank something off and make things worse)
3. I definitely do have some looseness in the 5 pin molex that connects to the motor relay board. The 12V wire has a little give in it and the entire connector has some left-right wiggle-room as well.
So, my next steps as I see it are as follows:
1. Evaluate and fix wire connection at the motor
2. If that does not fix my issue, make a new 5 pin molex. (if I get to that point, I will need some guidance on what to buy material wise to make molex connections as I don't have anything at home to do so)
Thanks for the continued input and thoughts.
