Hi gang

Have lost two solenoids. Top eject hole and diverter Hi/Low

Both have power to them. Although was unable to check the lugs of the diverter coil but checked coil side of the connector and it was present. That coil is buried and requires serious dismantling to get to!!

Continuity is good. Transistors not short to ground No coils locked on.

Any suggestions gratefully received
 
I'm assuming you're trying in coil test which rules out a switch issue.

You could try briefly shorting the coil's low-side wire with ground to see if it fires. If that works, it must be a driver board problem - either the mosfet or whatever is driving it. Do the affected coils have any common circuitry?
 
Yeah it’s in coil test.

As far as I can tell there’s nothing in common.
The main thick wire is Vio-yel on one and vio-org on the other although there is continuity between them 🤷.

I’ll try grounding the wire when I’ve got assistance so I don’t blow myself up

Edit: as per pinwiki I have grounded the tab of the associated driver transistor and it fires the out hole.
I can also hear it energising the diverter coil on its tip 102.

The other wire on the diverter is associated with a tip36 so I haven’t touched that as I know they operate differently.

Should grounding the pin from the board on J127 (outhole) or J130 (diverter) also fire it? I’ve taken a ground from the back box braid and grounded the relevant pins and they don’t fire
 
From memory, no it didn’t. I seem to recall. Last time I had a flasher and coil out it was a tip36. But that’s seems to test fine with the meter
 
You might have a problem with the D0 line from the CPU. Have you tried reseating the infamous ribbon cable?

Testing transistors with a meter is not 100% reliable.
 
Yeah I’ve done the old ribbon reseat. They fire when the tip102 is grounded so it’s not that
 
The reason I suspect D0 is because that's the common thing between the Diverter High, Eject Hole, and Right Bank Flasher. Enable 1 (the first magnet in the accelerator) is also driven from D0, does that work?

Ooooh ok. I haven’t checked enable 1 as I had no idea what that was🤣. I’ll take a look
Is D0 one of the data lines in the short ribbon?
