So I finished the playfield part of my resto of a BS Dracula on 1 April and it fired up with "no errors" and played well (April fools on me for thinking no issues were to come)
After an hour or so of intermitent play the mistball multiball started acting weird and Id get multiball for no apparent reason. Games would cut short then next game I'd get 2 balls straight up.
After running a full test I got a unload error for magnet/mistball.
I started googling and checking here...Ive been through all the tests everyone suggests and it seems to be the long opto beam. Its active when it shouldnt be.
Ive tried the tv remote trick and mobile phone camera to check both sender and receiver optos are working and they appear to be but the long mistball opto beam seems to think there is a ball there when there isnt...and yes Ive removed the gates to avoid any interference. It was working fine one minute, gone haywire the next so Im stumped. Also cleaned all the optos out and they are sparkling clean.
Also at the same time Ive had some flipper switches go a bit weird now showing issues when testing but when I manually test these in the single switch test mode they all seem to work fine, Im guessing maybe related to the opto issue? The coincidence is rather odd.
Ive attached some pics of the other switch issues besides the long opto beam for mist ball.
Anyhelp would be much appreciated.
