Hey folks,
I finally bit the bullet and ordered the new MPU1 board from Jim @ Echo Lake Pinball and installed it. Once that was done it was time for troubleshooting.
8 new bulbs
new rubbers
fixed one stuck switch issue
Removed 1 nickle and 3 paper clips from the left coin chute
installed new teflon feet
Now it's all working... except that the chuck-a-luck won't spin.
Any ideas on where to start? I'm about to tear the SDU board out and check for cold solder on the headers, problems with the driver transistor, and issues with the relay used.
It *does* recognize all the value switches when spun by hand during the diagnostics tests.
Thanks,
RJ
