Hi Lloyd,
I hope all is well.
The other day I turned on the machine and all of the coils and flippers didn't work on my 1993 Indiana Jones pin. I am new to diagnosing this and I wanted to check with you first to see if you had any ideas. I'm hoping it's just a fuse. Fingers crossed.
Thanks,
Little Maharaja
Hi Little Maharaja
All is well, other than people trying to take the fun out of helping.
For a start I'd pull F112 on the power driver board and check with a meter. It's on the upper right side, one of the four fuses in a row. It is your solenoid secondary fuse, a & amp slow blow.
If it is blown, and blows again, then next thing is check the fat diodes nearby, the four for your 50 volts. One or more may be shorted.
