Re: [HOn3] Headlamp no longer working on my C-16/DCC problem?
- If you shorted either bulb lead to either the loco or tender, maybe the
insulator on a wire got cut by edge of a hole it will blow the lighting
transistor. As said before the back up circuit can be used to power it with some
CV resets but make sure you eliminate the short first. AFTER you blow the
back-up transistor you will have to use a TCS accessory decoder to power the
16 volt bulbs tend to draw a lot of current. 1.5 volt 15 Ma lamps
are much better and LEDs better yet. LocoDoc

The only thing the TCS decoder won't give you is the ramp up and down on start up and finish but the cure is half the price of a Tsunami repair which is currently $45 I believe. The other way, and I know space is critical, is to use an old motor decoder, solder a 100ohm resistor across the orange and grey wires and set all the speed curve settings to zero. Set the ID to the same as the loco. If you're not going to program the motor decoder you can even remove the resistor after you've made all the CV changes.
- The 16v bulbs are 30mA max. I saw the 100mA max draw in the Tsunami manual that came with the decoder.
I checked for other shorts but all wires are good and the insulation is intact. I have yet to try the back up light (yellow) wire. What CV's would need to be adjusted/re-programmed to make the back-up light the headlight?
I'm familiar with the lower voltage bulbs and resistors however, when I did the conversion all I had on hand at the time were 16V bulbs. At this point getting the bulb out and wires re-routed with a lower voltage bulb really isn't worth the time and effort (it would involve some major surgery). I can live with it as is for the time being.
Thanks for all the replies. It sort of confirmed what I initially thought.

Each lighting output from the tsunami is good for 100 milliamps max.
The headlight output might be blown - possibly the bulb was pulling too
many amps. If you have not used the backup light output (yellow wire)
you could use that for the headlight - but I would check the current
draw of your setup first. In my locos I use a 1.5 volt bulb with a
suitable resistor. Many of my headlight bulbs have been working for years.
