Parts for M200 MPU board
pbj:
Also, on this particular board, should be able to find an empty hole close to the + point on the MPU. I generally solder a diode directly to the MPU and run the remote battery wire to that. It keeps someone in the future from leaving off the blocking diode. Having another blocking diode in your battery pack won't hurt anything.

Precisely what I was going to do.

if you really get in trouble you can get the board repaired very easily. Barakandl on rgp/pinside does a good job and takes trade in's. I ran an alltek board for a while then sold it for $5 less than I paid for it on ebay, and got a repaired bally mpu from that guy. working fine ever since.

I finally had a chance to test this board in METEOR. No go.
I am able to get 1 flicker, then 2 flashes. Which tells me U8 is bad. U7 is the same chip, so I swapped them, but got the same error. I've got a Lightning, so I pulled the MPU from it, and the machine gives me full 7 beeps/flashes, and the all tests work in test mode.
In play mode, none of the solenoids work.
I've still got some testing to do I guess!
ed12:
raise the playfeild up
find the 1a fuse
looking from the :front:,it will be on your left side
if it is open.? chk for a bad coil..if it is good?
your driver board is a tad south..or the headers that feed it ..both from the playfeild and or the mpu
