Quick Version: I did something stupid and over-fused my machine, have narrowed down the problem, but it seems to be on the board. I’d appreciate some troubleshooting help. If I remove the connector from the board J209 that is having the issues, I still get the same errors.
If I do need to replace the board, is it better to send for repair or just rottendog replace?
Long version: I just LED’d and replaced a ton of crap in my White Water. After turning it back on I got the message to check fuse 114 and 115. Only 114 was burnt. I replaced a ¾ amp fuse with a 1 amp fuse because I misread the chart/am an idiot. Fired it back on and the fuse immediately burnt out (so I 100% sent a 1 amp current through a ¾ amp circuit). I then troubleshot the machine and found that I had a switch that was causing a grounding issue and fixed it. Replaced the fuse, with a 1 amp fuse, and turned it back on. Got to the WhiteWater screen, test errors for all of the river switches, and ground row errors for white yellow, white purple, white grey, and white blue along with the VUKs firing like it is in ball search mode. I have spent over 4 hours searching for the ground in the machine, literally unplugged every connection to the upper playfield, and have found no shorts. I traced those wires all the way to their termination points, no grounds or kinks. In my desperation to fix the machine I went back and discovered the overfusing error and replaced F114 with the correct fuse. No change. After very carefully making sure the river switches had no grounding issues, I did a hard reboot on the machine (took the battery out) and the river errors went away, but I still have the ball search vuk kicks going on.
I figured out that my grounding error messages are all related to the connectors on J209 of the CPU board. If I unplug that connector, all of the error codes go away except for the white/yellow grounding error, which is clearly in J209 and leads me to believe that the problem is on the board. I have removed the board and carefully scraped excess solder away from iffy connection points and had no forward progress from this.
I’m running out of ideas on ways that I might be able to fix this and am open to ideas. If I did fry some connectors on the board I can’t see, should I be sending it off for repair, attempting something myself, or just getting a rottendog replacement?
Any and all help greatly appreciated.
