I am in the final stages of performing a PS3 upgrade on a Lionel PA and all is perfect minus the Mars light. It will light but not flash. I downloaded a sound file for a SP PA 20-20843 and it features a Mars light per the catalog description. The rear Mars light also does not work.
Should I try a different sound file?
I still have the original Lionel board that powered the Mars light, so this will be the back up plan if the PS3 feature refuses to work.
As always, thanks in advance for any advice.
