Hi all
This is my first post here, as I was shunned from the "other" electronics forum as they do not allow automotive posts. (makes no sense to me!), so HI
I am looking for some help with a motorbike brake system. I have build some led arrays, 6 leds each in series, then in parallel for a total of 48 led's per board, both boards wired in series.
A picture says a thousand words so here is the "circuit" Diagram:
Sorry for my crappy drawing, it was getting late and I was frustrated heh.
The reason for the resistors is that when the headlights are turned on the "tail" line is energised, at a lower current so that the LED arrays illumante dimmer, then when the brake is pressed, the "brake" line is energised, bypassing the resistors and getting brighter. This works when one array is connected, but is back feeding with more than one connected.
So when I connect the second LED strip (at the bottom of the diag), the LED arrays go out (when on tail mode) when on braking mode everything lights up as it should. Its my thinking that I need some diodes at A and B on the diagram, can anybody confirm if I am on the right track
