I picked up a very clean Godzilla with acid damage to the MPU and driver . Found a great MPU and got new game roms and new driver board . I have played 50 + games now . After 2 or 3 games the power to the flippers seems to fade to nothing . When you turn the game off and back on everything is back to normal . You might play 5 more games with no problems and then ....flipper power fades away . It is odd when it happens . Not like you hit the button and they are dead . More like they are half way working for a second and then nothing . I had trouble finding a 520 5136 MPU and got a new 520 5300 and all new roms . The driver is a new Rotten Dog. Later was able to find a great 520 5136 and used all the original roms from the acid damaged board except the main game Rom that was under the battery . The problem is there with both of the MPUs . Any ideas where to start ?
thanks Scott

Flipper go from working 100% to zero but it takes a couple of seconds . When you turn the machine off and back on again
they are back at 100%.

OK I checked the flipper coils and they are not hot They are barely a little warm . I checked to see if the white button solves the problem like turning off the machine does . It did not fix the problem . I played the machine and did see what happened . The red light on the driver board went out . It is the one left of center on the board ...again it is a Rotten Dog board . When I turn the machine off and back on again the light is back on and the problem is gone . Is my new board bad ?
Bare with me on this .It is my first DMD machine . I have been working on SS and EM games before this one .

Yes the board was new three weeks ago . I sent an email to Jim at Rottendog about it .
