Bachmann ho dd40 (latest run) strobe light question

[sbeck80]

I recently replaced the stock Bachmann DCC decoder with a Soundtraxx one and now my strobe light doesn't work. It appears that the strobe has its own light board and has 4 wires going to it. Anyone know what Bachmann did here and how I can fix it either by wiring it or by a value in the Soundtraxx decoder? 

Also - there's not much documentation on the board in this thing....I see a bunch of other tabs for more led's.  Are these the F5/F6 tabs?

The instruction sheet that came with the decoder shows how to wire up FX5 or FX6. There are 4 tabs on the side of the decoder. One is for F5 the other for F6. You need to down load the decoder manual from Soundtraxx to set up the strobe. There will be a chart showing different strobe types and how to set the flash rate.  Joe
