Tech: Xenon inner chase lights

[Guest]

Hi there,

Working on my Xenon and am having issues with the chase lights on the inner
circle not flashing in the proper sequence all the time. Actually the flash
properly for about 7-8 seconds then do what they want for 7-8 seconds. The
time varies, but that is what it does a lot of the time. Doesn't seem to
matter in game or attract. I can only assume whatever chip that controls
these lights is going haywire? The perimeter chase lights and inner small
circle function without a problem. Any one see this issue?

Hi,
From the schemas these lights are driven by the aux lamp driver.
I would do the following:
Swap u10 and U11 on the mpu board (it could be a problem related to the
6821/6720)
Check the connectors from the aux lamp driver.
Greetings Oliver
