I try to help a friend's Guns.To be honest I don't like too much DE,because they remember me the old style of System 11,so my experience on DE is not so much like W/B.

What I done until now:
First rebuild the whole PSU because it was damage everywhere.
Also replaced the relay on PPB because the old one get stucked.
Repaired the +5V connector on DMD controller board with new one,because it was burned and didn't show nothing on the display.
Now the machine work-the program start normal,the gameplay look normal,DMD work great,sound work too.Everything is functional normal except the coils on +50V and the three flippers.

The problem:
All coils which are 3-4 on 50V didn't work
All three flippers didn't work except the right one which work but very slowly.Flippers board diode not light.

What I try:
For the flippers I tried with another working board but same problem and the diode on it still not light.
Interlock switch is ok(this one on the coindoor).The one that tell when the coindoor is opened and that the high power will be disable.
The other one is disconnected and I cannot find it's wire on the cabinet,so this can be solution for the problem too if someone tell me the colours of the wires.
Tried another working PPB board-still the same problem.
Measure the voltages on PPB on the connector under the relay which the manual tell that must have +50V,but nothing.No voltages.
Checked all BRs,fuses-ok

The machine have many previous strange repairs,so this thing will be some stupid thing I think,but I don't know what can it be to cut these +50V.

What I think to do:
To trace the whole path of +50V.Can you help me for these?
Some other test points to see if there is +50V?
Any other idea what to try?

C1 is new.
BR was checked two times and it's ok
Th fuse is fine.
As I wrote,I tested with working board and the result is same.

Will check these ACs later today.
