NEWBIE LOOKING FOR HELP
I have HMM that stopped working after I invited a tech in to help with the ball shoot. Now I'm thinking I will make it my project to get it working again. Not an electrician and new to maintaining the machine so any advice out there on where to begin to diagnose what is going on? What tools do I need.
I have the original manuals and schematics
Added over 3 years ago:Update. Turns out it was a blown fuse. Machine now powers up, bumpers, slingshots, etc register score BUT none of the solenoids fire. The flippers aren’t working either. The basic function solenoid test displays all the solenoids so I assume they are powering up. I’ve changed the playfield fuse several times (and even removed it altogether) with the same results: no flipper action, no bumper action or any solenoid action, and balls are not being ejected into the shooter. Could there be another fuse I missed checking? Maybe the fuses I am using are old?
