Howdy!

Happy weekend.

So, I've just restored my WPC-95 TOTAN (decals and all), played it and then turned it off and put it back into the corner of the room.

Now the error check F101 and F106 error shows on the DMD. When investigating F106 was blown and I simply replaced and turned the machine back on. The Fuse blows straight away.

Long story short... I disconnected all plugs to the power drive board and identified that the fuse only blows when the J129 connector is plugged in.. (also noting that its getting 14.3 volts to pins 4 and 7 on that connector). When Tracing back the blue and red cords to the transformer.. all looks good.. What could be wrong?

Any ideas would be amazing!!

Thanks in advance.

immediately Run_dll .. as soon as i flick the switch under the cab, i see a purple flash in F106 ...
Would any solenoids fire if nothing is plugged into the board except for F106? I was wondering if it was an earth cable touching a led or something.. but considering everything is unplugged (even including the ribbon from the cpu to driver board) it doesn't make sense...?

zaza Thanks!! Looked like all 4 of those are giving a really strange reading (shorted) or no reading at all. I assume I need to replace these, what would cause these to short? Could it be linked to something else on the board?

Thanks mate, ill give it a go during the week.

I also wonder if it could be from a short from a solenoid or similar? I was testing the left hand side ball save / cage before i shifted it and it did seem to be losing power. I now suspect that would have happened from a failing diode/s.

Thanks for the info!
