I have an older MRC AD370 sound decoder. I have the sound and forward reverse all setup. That is working very well. Now, after frying the light bulbs I have new ones. I have this plugged in with the 8 pin circuit board. The decoder comes with a 10 pin JST plug so it does not really plug into the JST connector on the stock Athearn DCC ready board.

I have one light bulb hooked up to the two front solder pads on the stock Athearn board. The front light goes on when moving forward and goes off when it goes into reverse. That works the way it is suppose to. Now, when I put my meter on it I get 1.6 volts.

I would like to run separate forward lights and ditch lights. If I follow the direction that came with the decoder, I get 4.5 volts from the solder pad to the wires of the DCC unit. I have not tried form wire to wire, so I am not sure of the voltage there.

Now, here is my real question. Is there a spot on the stock Athearn board to solder the light bulbs to and get ditch lights and forward lights? I have tried the meter and all I get is 4.5 volts form any wire.

From what I can see, I would need to get a higher voltage rated bulb or run a resistor to drop the volt/current?

Any book, article, I can read or should I just run screaming from the building?:eek:


Buzz.
