I'm still learning the older Stern system and need some help here.

I've got a Stars that while sitting idle had the left slingshot coil burn up. In checking for damage, none of the fuses on the rectifier board are blown and all voltages are in range at the test points. I shifted my attention to the solenoid driver board and it's fuse was good and all TIP 102 drive transistors test good. I clipped the ground wire off the left sling and the game powers up. All switches, lamps, and displays work. Both flippers and chimes work but all other coils do not. What's my next move? MPU is an Altek if that matters

Thanks in Advance,

Mike V.

Fuse under the playfield near the flippers. Fuses all the playfield coils except the flippers for some reason

I didn't realize there was one there - I will give it a look.

Thanks for the help - I found the fuse, replaced it, and Stars is now playable again.

It's great when it's something simple, Occam's razor!!
