Help with Reverse Light
Charles Goddard <CGALFA@...>
I have BLI Steam Micados lacking Reverse Lights. The QSI Decoders are 301-1 with the Quantum Upgrade Chip. I've been told by a contact how to do this even with photos.
When I make the connections to the REV positions, right being positive, it does not work in reverse of forward. Do I need to make settings in CV 29, CV 33, and CV34, other than their originals? The suggested resistor was 100 ohm, which I didn't have, but a 160 ohm was attached on the short side of the LED, and allows light when attached between the rails.
What am I missing?
First thing I'd do would be to flip the polarity of the LED.toggle quoted messageShow quoted text
I don't have that model, I do have a ATSF 2-10-2 that did not come with a rear light. The pcb has holes for a rear light connector and pads for a SMT resistor for the light, both of which did not have any parts loaded in those positions. The connector is not a issue since you can solder the wires coming from you LED to those holes. But without the SMT resistor there's not a connection from the decoder output to the connector holes. When I added a light, I soldered an SMT resistor to the pads, if you don't have an SMT resistor you can keep using the resistor you already have but you'll need to solder a wire across the pads for the SMT resistor.
By default the rear light should be enabled thou there are CV that can disable it.
