Not sure where is best to post this, Tech, Wanted or "I'm an Idiot section".
Yesterday I decided to strip the ramps and underside from my Addams and do some more cleaning. A full rebuild left me with two missing screws for the THING kickout switch, a switch that did work anyway. I decided that I would cable tie it to some cables to keep it out of the way and order a new switch.
The game all worked fine but a problem with THING lead me to go want to adjust his enclosure and for quickness I didn't switch the power off
. I didn't notice but I knocked the cable tied switch and as I was shutting the machine it touch the THING kickout solenoid and shorted the machine.
Test mode gave me a ground short in all but one switch row, then as I started to trouble shoot the number got less leading me to believe it is not all shorts but the LM339 at U20. I have used the usually help and repair guides and concluded the following.
If I disconnect switch connection J212 on the WPC board and THING under the playfield, I get no ground short errors but loads of other switch issues. However, switch test mode gives a short on ever row for the switch tested.
Before I replace the board does anyone have any other tests to try?
Does anyone have a WPC board (TAF compatible) that they want to sell me? I am not asking for a lend in case there is another problem with my machine that would damage another board.
I am not confident enough to replace the LM339's on the board just yet, I would like some practice on something a little less valuable. I am willing to literally pay for my stupidity and I am not happy to now have no machines at home to play.
I have already spent 3hrs in the naughty corner for being an idiot and not switching the machine off. I got away with it so many times that I forgot the consequences. Let this be a lesson for you all, cover lose wires and switch your machine off or it will go bang.
