Hello,
I have a Spectrum Steam 4-8-2 Heavy Mountain with a Tsunami decoder. The headlight is very dim.
I've tried adjusting the headlight CV49 to the 'Dyno-Lite' setting 15. If I do that the headlight won't come on at all. If I set it back to 0, it will turn on/off but is very dim.
I'm new to DCC...any ideas?
Thanks,

Some of the 2-8-0's had the same problem. Replacing the headlight bulb with a 3 mm warm white LED with a 1000 ohm resistor in series looked much better. The blue decoder lead is positive but there may well be changes in colour coding between the decoder and the light. I usually just hook up the LED (with the resistor in series with one leg) and try it out. If it does not work, I reverse the LED leads. If you need more information, just ask. We are a reasonably friendly bunch here, which is to say we sometimes bark but hardly ever bite.

Just a thought, on my Tsunami engines, function button 7 is used to dim the headlight. Maybe, for some reason, your Tsunami is set up backwards for this funtion. Try pushing button 7 on your throttle and see if the headlight gets brighter.
