Hi All - so i'm reviving a dead 8 ball. Have fixed the MPU so it now goes in to attract mode. Got the displays up and running. No Sound but I will get there.
1A playfield fuse was blown. Put in a new one and ran the solenoid test and it popped the 1A fuse again. So I decided to sacrifice a few fuses. Ran an earth to each Tip on the Driver board to activate each solenoid one at a time. All worked fine except for BOTH slingshots and middle (lower) Pop Bumper blow the 1A fuse. It would fire the coil but then pop the fuse.
So must be a short?
Checked the diode on each of the 3 coils - all ok. Checked the coils out of circuit with the diodes off. Slingshots 7 Ohms and Pop 3.7 Ohms (all 3 seem ok to me)
No wires on the switches are touching anything they shouldn't.
So what next?
Ta in advance
