I reviewed posted threads and explored the internet but remain uncertain how to proceed.
I revived a 2-8-0 from my junk pile with a parts purchase from Bachmann. I will say Bachmann did a great job with my order. I had removed the circuit board a long time ago so I retraced the hard wiring and installed a TCS T1A Decoder. All programming went well except I can't get the front light to light.
The Model Spectrum is 11410. Bought new guessing 2005 or 2006 era. I'm not sure if existing light is a bulb or a LED. The parts list looks like a bulb. I did wire the light to an aux power source and slowly increased current until the light lit green and then backed off. So the light appears to be ok...
As to wiring...and to be on the safe side I installed a 1K ohm resister between one of the light wire leads to the blue wire lead of the decoder and the other light wire lead to the white wire of the decoder. I then switched around the light lead wires...same results..still no light.
Questions:
1) If it's a bulb do I need a resistor? Could having the resistor installed be my problem?
2) Is there a CV Function that permits the light from lighting. I use a Lenz LH100 Keypad. In all my years messing around with DCC and decoders...I never had to be concerned with any associated function.
3) In checking the resistor, I had conductivity across the leads.
Any help of course is appreciated.
