Got a Willaims fire to repair yesterday. I have owned numerous machines, but the newest SS I have worked on is a Gottlieb system 1. I am very good with electronics/componet level repair and not afraid to dive in, but wanted to see if anyone had some pointers on Williams system 11.
I have been googling and have found lots of good info. Basically I have not plugged it in yet, looks like the usual stuff though. Test the power supply output first, relocate the batteries off the board, check fuses, reconnect power supply and power up, run through diag.
I've also read that these machines need some additional fuses on the transformers as some have started fires.
Any other good info or system 11 links appreciated! Thanks!
