Aaargh, feel like smashing this machine. first helicopter motor rewind, fault finding as a column of switches had intermittent fault. Fixed that and game was amazing. Got my highest score and the very next game there was a bad electric smell and turned of machine. had a look everywhere and could not see anything burned. looked at all boards and no smell in there, all looked good. Started game, no sound, no flashing lights( just a few solid lights like under bumpers etc working and no flippers. I cannot go into test mode with flippers not working. I pulled all fuses and they look fine. Please help

Hi Thanks for the advice. I did check all fuses with a DMM. They all tested fine. I disconnected all plugs from board and switches. Top right flipper felt a bit tight to move. I gave it a good workout by hand and now it moves easy. when I restarted the game it came up with coin return. pulled all plugs I could find in the door area and restarted game. It all seems to work ATM. Must have been a loose plug somewhere or maybe the top right flipper coil. I really appreciate the advice. Thank you

top right flipper was very slow. Do you think that this is my problem. It seems ok now. Maybe I should change that coil in case. I am sure something would be melted as the smell was bad.
Thanks
