A third green light on the EZ start controller although inside it?

[Super RC Driver]

I was working on my Revo just now and I was turning over the engine and I saw a green light inside it. Not sure why it's there, but Traxxas must have had a purpose for it. Here's a vid of it.

What the heck I have never seen that before. Maybe it`s always there and it just never got seen.

[Super RC Driver]

Lol. That's what I was thinking...

I just checked mine and it did the same thing it looks like there is another light in the back of it.

i think its just something they had put on the electronics board to indicate the circuit was working properly

Sometimes they use LEDs as diodes.(which is basicly what a LED is) They probably bought a bunch of the green LEDs for the lights and decided to use one as a diode.

good call nstampede

It is not basically a diode, it is a diode, a Light Emitting Diode. LED's are very inefficient as they have a high forward voltage so my guess would also be circuit verification. When the board is done and in QC it is is probably powered up and a camera or light sensor verifies that it is on to determine if it is a good part.

That's what I was going to say.

Weird though...I never noticed that.

Not always true. They DO use LED's as diodes in electronic circuits. All diodes emit electromagnetic radiation. LED's just emit it in the visible spectrum. When they test electronic circuits boards, they usually hook it up to an computer. It would be a waste of an LED to use it purely for testing IMO.I am not saying that you are wrong though. I wish nitro chicken would comment on this......

I'm a former e-tech with Ciena Corp. and QC would love to just look at a curciut and see if it is getting juice rather than use their meter to check for continuity.

I never noticed that light before. But I just checked and I see it.

LED's have a very high forward voltage and are rarely used as diodes only and when used they have a purpose. The ez start wand does not have a micro controller inside so connecting a computer will not be able to test it as it requires a physical input, the button, to activated it. It is also very expensive to provide a port to connect a computer. The circuit board on the ez start wand relays on a set of simple logic components and by powering it and pushing a button and having the LED turn on will be a simple verification.
