TAF issue

[Brownfools]

Scratching my head on this one!
When starting a game all three balls are kicked out (one at a time) into the shooter lane. Once all three balls are in the shooter lane the solenoid stops kicking.
This may, or may not, be related to another defect that seems to have occurred at the same time where the contacts on the bottom left kicker are dead. Although the solenoid operates in test mode.
I cant find any loose jumper connections.

For a kick off, empty all the balls out, go into switch edge test and try all the trough switches, the shooter lane switch.

Thank's Stroby! Yeah, second switch has gone.
I was led slightly astray by trying to associate it with the other fault. I've make that mistake before. Schoolboy error.

The other fault (left slingshot switches) was more interesting. I discovered that there were a few other switches not working. All on row six of the matrix. But some did work. Therefore there must be a break in the chain somewhere between a working one and a non working one. So, for a left slingshot fault at the bottom of the table, the cause was a wire detached from the "A" of "GRAVE" at the top of the table.

I'm a happy bunny again. Thank's again, Stroby!

No prob, glad you found the fault.

Btw once you've fixed all faults you'll not get the "Test Report - Press Enter" alert at power up.

You'll also notice the freeplay / credit dot disappears.. eg

Credits 1.

The dot is a subtle indicator that a fault is present.

Best of luck, great pin you've got.
