Help with a led and OKT

[snails1023]

Hi ,
I built the OKR-T VV mod , but now I want to put a led in it, where does it go in the wiring?

 

[Dalton63841]

In parallel with the atty connector. hook it to the same hot and ground.

Thanks, I didn't want to blow it up or anything. LOL

LOL I don't blame you. Always better to verify. Don't forget you should also have a ~200ohm resistor in series with the LED.

Don't forget a resistor....

don't some led's have a built in resistor?

 

[Jetmec]

Don't know about built in resistors but led's do have a + and - and will not work if you get it backwards.

 

[snails1023]

I figured that the resistor had to be added anyways, but thanks for the reminder.

why would you not put it on the battery side where the voltage is constant? or is it just more reliable to put it on the output side?

Radio Shack has some, but they're a little big, not a problem if you have enough room.

Radio shack also has some very small ones rated for 12v with resistors already on them. They work very well on my OKR-T mod. Just connect it to the wires going to the atty connector.

The advantage is in the fact that it lights when the atty has power. I guess this would only really be a useful indication for trouble shooting similar to the idiot light on your cars dash =]

i was going to convert an existing mod to vv - it already has the led in place i was just going to leave it alone it would end up wired parallel with the vv circuit but still would show when you fire just not that there is output on the vv. i do think i like the idea of the led after the vv for troubleshooting reasons but is there any reason it wouldn't work with the led on the input side?

I guess it would depend on how you are switching your mod. If you are using the control pin on the okr it won't work as the LED would always have power. If you are using a high amp switch and switching battery power it will work.

um yea standard 3a switch on the neg leg (standard box mod) - i was just going to move the existing positive off the atty to power the vv and add the neg lead off the button where the atty and led are wired to. positive from vv to atty. simple add on / switchover to vv and leave the existing switches and led in place. if anything can ever be that simple lol
