Reply to "Train America Studios SAW V1.5 Interface to MTH Smoke Unit Interface"

My diagram is indeed a "generic" smoke unit reference, hard to make one for every specific smoke unit.   The fan runs off a regulator, and even though you drop the voltage on the smoke unit, it won't change the fan speed. However, you still get the lower smoke at idle effect as it lowers the heat in the smoke resistor and you get less smoke.  You may have to "tune" the number of diodes to get the desired effect, sometimes I have too many and I don't get any visible smoke at idle.

I think some of the E6 units may have had a single reverse light, but I'm pretty sure I never saw markers on them.

If you're using bi-color LED's, how are you driving them?  Note that they have to be common anode if you're triggering on the forward/reverse light outputs.  Also, you need to add the .01uf caps across the lighting outputs, and if you have series diodes for the smoke, you need the .01uf cap across the smoke output of it'll stop altogether.
