I need some help from the experts. my test reports shows
-check switch 35 right slingshot
-check switch 34 left slingshot
-check switch 87 gumball enter
-check switch F1 right flipper EOS
where should I check first? I checked the fuses and they tested good.
any help will be greatly appreciated.

Go into the switch test and verify each one. After 30 games played the cpu puts up an error message stating the nonworking ones.

Sound like you may have some bad switches and or a loose wire on the slingshots, I would go in to switch test and verify the switches do not register, F104 controls the slingshots and 5 other coils, so its unlikely its bad, but the fact that non of the 4 switches on the slings register is odd. 87 is an opto switch and could be dirty, and flipper EOS is commonly broken or misadjusted, I am guessing the slingshots do not operate ?

slingshot does not operate at all.

Do slingshots work in coil test ?

If they fail in coil test, do you have multimeter? You could check coils (failed one’s). If coils are given enough ohms, check diodes if there is. With additional measure leads, check that coils are getting voltage during the coil test.

If voltage is low, then problem could be in transistors, from manual, you’ll get exact position where to check...
Also is worth to check that wires to coil from i/o card are ok

NO slingshot do not work in coil test. how much voltage should I be getting during coil test? what is considered low?

Coils are not the problem coils very seldom every go bad unless they are fried.Check fuses pull them out and test with meter.Also look into the wiring going from switch to switch it’s possible a wire came loose or a bad diode on one of those switches starting with the first one on the switch matrix chart in that row.TZ does not have a hi power kill switch so If coindoor is opened the hi power is still active so power off game when looking underneath playfield so you don’t cause a short

Are there any other coils that don't work in solenoid test ?
