Nitrous LED light doesn't turn red when switched, is it just a burned out light?

Nitrous LED light doesn't turn red when switched, is it just a burned out light or something more? I had switched it on and right away it went red for like half a second then it went away so does that mean it burned just the light out and the button will still activate the nitrous ?

Whip out the multimeter and it will answer your questions for you. Its rare for a LED/Switch to go bad. If either does, an extreme amount of electricity was passed through there or you've just been using it for 100 years

So the switch may be still good but the LED light went out? It is the stock button for the wet nitrous Sniper kit made by Holley

I'll do what you said when I can get my hands on a multimeter thanks!

FYI this is the internals of those LED toggle switches. If your N20 still works then the ground prong on the switch could be disconnected (grounds the LED is all it does, no. 3 prong)

Test the led by connecting +12V to #1 prong and ground #3 prong. Or use the diode function of your multimeter.

Hey Thanks for that.

It looks like everything is grounded to me:

Haven't had the opportunity to test it out but would you say it'd be safe to attempt to use it?

I mean it's only a light but I'm not much of a experienced guy when it comes to these setups. I don't want it to spray only fuel or vice versa etc

Disconnect the output and put the positive of the multimeter there and ground. Flick the switch, if you see 12 volts, all is good, if you see like 6 volts, check grounding, no voltage, its borked.
 
Not sure why you'd need no2 unless its a drag car.. and if so you should be able to figure out a simple switch LOL

Really? ROFL Now I should reply 'not sure why people get turbos unless it's a drag car..' LOL everyone wants power man and there's multiple ways to make it.

Anyways good useful post there I'm sure if you keep it up you'll have a good post count soon.

The shop that installed it (Lopers) said they'd take a look at it for free tomorrow but thanks for the friendly help LOL
 
You'll have to toy with it to find the outwards power. One of those is ignition power, so probe for 12v when the key is turned to on and the center one is usually ground, so the last one has to be the 12v out. Its hard putting this all in words, if I was there, could have it diagnosed in 10 seconds.
 
And why do you have GSX rims on a GS-T?

if his profile is up to date, it doesnt even have a turbo... just look at the diagram a few posts above me, its a simple switch. if your still confused, check you local auto parts store. those switches are all over for like $8.. just replace it?

Got it fixed today guys! :hellyeah:

It wasn't the switch or the ground.


It was the fuse to the cigarette lighter. They replaced that with a new 15A fuse and it works now :)
 
What does your switch control? It may not be a good idea to use the lighter circuit for things that draw some good power. If it is a high power thing you may want to look into using a relay and running power from the battery or the underhood fuse box. I don't have a clue what a No2 setup is but it's generally not the best idea to use power from the cigarette lighter circuit :)

Point is I'd want to find out why it burnt out. Fuses don't just wear out and get old like a maintenance item, either there's a problem or there isn't one and the fuse is a telltale to whether there is or not.
