I’ve done this before but i cant remember how and i’m wondering if i may have other problems. But, can someone please again tell me how to wire a headlight to the remote accessory wires on a revo?

Is the ground (black wire) used or are the colored wires switchable grounds?

Thanks,

Terry

figured it out.

So, how’s it done?

With wires. (http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)(http://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-tongue-out.gif)

Terry,

Do tell. The replies do not help anyone! (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-frown.gif)

Simple, but if you aren’t hooking up a revo, what do you guys care?

The Revo is like other decoders, i.e. DCC, the common is in fact positive, and the “outputs” are actually “inputs” an open collector transistor to ground.

My guess is that the headlight is an LED and the polarity was backwards.

(how’d I do Terry?)

I don’t speak Revo, but that sounds about right. My G Scale Graphics speed controllers are the same. Lighting outputs are common positive, switched negative. I think Tony’s boards are the same.

I was trying to wire up the stock lamp not an LED. Red is positive black is neg to get it to work.
