Hello, I am working with the side mirrors on my 2013 Ford F-250 which have side light blinkers. I am trying to add a sequential arrow blinker LED to the mirror but it seems that maybe the power does not drain quick enough on the trucks power to allow this LED board to even turn on once. If I connect power to it from my mirrors defrost power, it works just fine, but of course the power has to toggle on/off in order to sequence the blink. I hooked up a meter to read what happens with the voltage on the blinker power and it seems like it never actually reaches zero volts. So my question is, what can I do to get this mirror power to completely toggle off then on so that my blinker board will work properly? Any thoughts or ideas would be GREAT! Thank You

 

You left us hanging.
So what are the mirror blinker voltages when on and off?
How are you connecting the sequential circuit to the mirror blinker?

It makes no sense when you say the power never goes to zero, but the sequential circuit doesn't work.

 

What LED board? There is no LED board in your post, so obviously it is not the problem.

I think the led board functions fine. The on voltage is around 13 volts when the truck is running. The voltage drops to approx 6 volts in the off state. If I touch the led board to a constant 12-13 volts it cycles fine. It seems like it would be so simple but in my case it doesn't appear to be.

 

The on voltage is around 13 volts when the truck is running.

Is it still 13V when you connect the LED board?

 

Yes, the truck wiring seems to go 13 volts to 6 volts on / off

Actually, thinking about it, I believe you will need to wire a steady 13V from the turn-signal switch when it's actuated, so that the LED sequence continues even when the regular blinker blinks off.

Thanks, I might have to go back to the drawing board on this one. I figured this circuit being just a simple toggle on/off would work on this LED board but it seems more complex than I originally thought.

I am finally getting back to this... I played with it last night and verified that this LED board requires the voltage to toggle in order to work. That is ok for me, but I hooked up an electrolytic cap across the leads and put my meter on only to find that doing so makes the voltage constant. I just cannot figure out how to get this wire to truly toggle ON/OFF.
