Hi All,
As I dive deeper down the amazing spidey hole, after re-pinning edge connects, a new voltage regulator I have a working game! (wohoo!).

The only noticeable issue I see right away is two of the three kick out holes don't work, (the ones on the outside). I believe I read both of these work on the same coil. I am not at the machine at the moment and was going to lookup prices on new coils and was wondering if anyone knows which coils to buy to replace these? I don't see anything in the manual that mentions that.

Asside from replacing a coil, is there anything other qwerks that might be the cause?
Many thanks,

Batsy

I do have a schematic, but I didn’t see anything in it mentioning the kickouts other than mentioning it’s switch xx.

I’ll check to see if the score registers and I’ll see if I can clean/test the switches first, can’t quickly identify which coil is responsible for these kickouts anyhow.

Looks like a bank of drop targets are also stuck down and not responding too.

Thanks for the feedback!

Looks like there is two 1Amp SB fuses on the bottom side of the play field. One of those seems toast but i don’t have a replacement on hand.

I’m hoping it controls the bank of 5 drop targets that aren’t working, but also wondering if it could be connected to the outside kickouts not working as well.

The kickout seems to be registering points and the 1 light goes out, it just doesn’t kick the ball out.

Anyone know if the kickouts go through a fuse?

Shoot, since my outhole, left bank and one of the kickers are working that suggests the other blown fuse is probably just affecting the right bank reset.

That means 1 and 3 kickers not kicking out is a bit more complicated.

All of the wires do appear to be connected, this just leaves a driver board issue or the coil itself I’m guessing. Here’s a picture of the coil, it’s wrapped in electrical tape for some reason so that has me questioning it.

Can anyone describe the procedure for testing the driver board transistor for this coil?

Perfect, TY

I'm having wierd issues testing my coils, I don't get a solid reading on any coil (even working ones). When I place the leads, the reading bounces all over from .2 to 60.0 then stopping at OL. I just have a mastercraft dmm, is it possible my dmm is wierd?

Having a hard time isolating whether my issue is a driver board transistor or the coil itself. Pinwiki indicates a transistor can still test ok even though it is bad and without getting a solid reading on any coil I can't tell whether the coils are good are not...

Should a coil test bounce around?

I watched a youtube video of someone testing a coil on a system 1 pinball and the reading was constant. I'm guessing my mastercraft dmm is garbage.

Meter is practically brand new (battery too). I'll try disconnecting the driver boards make sure nothing is pulling down readings (pinwiki doesn't mention that :\)

I have an equally bad feeling about this transistor as I do the coil... I wonder what the wire double backed on itself on the bottom leg does.... I haven’t seen this in any other boards?

Yep it’s the transistor for the coil that isn working, I just need to verify if the transistor is bad or the coil. Seems I need to remove the driver board to test the transistor so I’ll have to try that.

I haven’t got stable readings on the coil yet. I’m hoping once I disconnect the driver board to test the transistor from behind, maybe the coil readings will stabilize. I’ve successfully tested other things like the bridge rectifiers so I know the meter is generally working.
