hi,

I have been trying on and off to fix my Whirlwind that i bought 1,5 year ago (!)
The game did not work when i got it, and the people i bought it from never had it working.

I have several errors with it, so after switching out the relay and other things on the aux power board, reworking the power and the interconnect board, i am back at the switch matrix.

When i test the switch levels as per pinwiki, switch column 9 of 1J10 to 1J8 all pins, dead.
Switch rows in switch levels test from 1J8 1 and 1 to 9 of 1J10 all good.

The errors i get when i go into test are:

Any and all pointers are appreciated!

Update:

All the switches on the playfield are working in test mode when i touch them.

More update:

Testing the realy on the Aux powerboard with aligator clip on Q8 and the other lead on tthe ground strap, it does nothing.
But when i test the Q8 quick and dirty (recently replaced) it is fine.
I have never gotten the A/C realy to function properly, i guess there is somehting deeper in the game not working.

Help me Obi Wan Kenobi....

I have to confess that i am very close to buying new boards for it...

When i am i test mode, and touch the switches, they are fine, but in test mode, i get switch errors on the same switches that are working.

One of my main concerns are the A/C relay not working.

I will be back at the club house tomorrow to do some futher diagnostics.
