Playmatic Chance MPU Problem
ChadTower:
I still say going to RGP and asking around is the best first step.

For instance, Playmatic chime coils are really Williams score reel coils.

Why do I even bother?
Once again - Have you checked your playfield to see if there's another coil with the same number on it? Measure the resistance on that coil and buy a comparable coil from another manufacturer.
Drop target coils aren't fired all that often, you've got a -lot- of leeway in terms of what you can get away with so long as it physically fits.

There is another coil with the same number, but when i try to measure it my dmm just shows 0, and i know the coil is working.
The manual says all coils are 280 ohm, but im not so sure if i can trust that, it also says the coil for the drop targets are AC-1006
DarkSide:
AC-1006 is to small, i have no idea why the manual says it would fit, guess its a typo.
DarkSide:
I did, 3 times even.
It shows 0 on my DMM, both in the machine, and out of the machine.
ChadTower:
Then it is shorted and is not a good coil or you are not measuring it correctly.
