Evo-R fog light issue (need help plz)

Sicnarf · 07-28-2015, 09:03 AM

Anyone would have a clue to what I could test next?

When you measure all the wires, one is constant (12v), and the other is only constant (12v) when you hit the brakes? I don't know how the EVO-R light works, but if it does the flashing internally, then something is wrong with it.

It's 12v, so you can wire up +/- to battery terminal. Based on my assumptions the 3rd wire is "switched," so momentarily connect it to the + terminal. If it doesn't flash, then the internal flashing circuit isn't working.

Yeah thats it, 12v constant on one wire, 12v constant when brake is applied. But nothing is flashing and the light is always fully light up

Alright, so the internal flashing circuit isn't working. Ask for a new one.

Already tested the wiring , got it done by a electrician friend

Just my simplistic assumption:
The constant 12V (ignition) feeds the LED driver or transistor (FET). The base/gate is pulled down to ground so it can stay off. The timer chip gets power from the brake wire and normally starts pulsing immediately. The output of the timer chip feeds into the base/gate of the transistor, possibly pulling it high (12V) to turn it on driving the LEDs.
