My ST pro has multiple dead coils, not sure the cause. The Trough, auto launch, pops, right slingshot, and vengeance coil are all dead.
Fuses are all good, and some coils (upper right and left flippers, left sling etc) powered by J8 are working, so not sure what to check for. 
All connections appear good.
I appreciate any and all help.
Thanks
I visibly inspected them all (the red lights are all on) and I pulled F7 and double checked it with a multimeter, isn't F7 the one that powers the high voltage coils? Or is there another I need to double check?
Ah found the reference in the manual, looks like I should pull F8 and F5 double check them as well :face-palm
Making sure you used a meter - visual can lie. If they check out, look for a broken wire, coils are often chained.
