Hey guys .. I have a sega Harley here ... checked things over and when the door is shut top right flasher stays on and the top turbo bumper .. :/
I have looked in the manual and tried to isolate and see if any of the power wires or signal wires are going to ground but nothing found ...
Recently changed q29 and it’s still good just checked them all over again .
I only close the door for a quick second to test and flasher on and turbo same time so it’s something in the higher voltage section but what ? Can it be the relay on the board I’m not sure how to test that ... will try and attach a video .
Thx for help in advance .. no one else to get it from .. thx

I actually have a separate issue with display power supply it’s resetting , tested everything and have no 12v coming out but have the 18+ at cn1 ..

So something cooked in between so sadly no diagnostic mode for now ..

I did disconnect j10 and unplugged the one flasher connector under the playfield .. it stays in attract mode no further issue but not sure what’s going on the I/o board tests out ok ..

So I pulled my cpu board out of monopoly ..

Game fired up no issues and played fine .. so must be some type of logic or upstream issue I have no idea on repairs so will send the board out for a checkup and test .

Thx guys for trying to help .. appreciate your time
