Well apparently my gas light doesn't work what leds are tied into that circuit?

 

i still say the resistors are unnecessary...

of course if you change them out they'll be brighter.. (DUH..)
but that's not the point i was trying to get to.

what gas light? the low fuel light? nothing is tied to it except when you have low fuel, it'll turn on. if it doesn't turn on and you're at the R line.. then you got an issue.

if you have fuel in the car, the light isn't going to turn on... and you know know if it works or not until you're low.

 

Obviously I know how the low fuel light works I'm not retarded.....
I ran the car to an empty tank on my way home from work got to the R and no light keep driving think maybe I recalibrated it way off. And oops started to cut out almost ran outta gas right by the gas station. So it definitely is the led. Your saying there's no other leds tied into the gas light? So then it has to be that I burnt up that led, right?

 

most likely you did burn the LED , or may have accidentally put it in the wrong way. and also possible you did not calibrate the needle correctly.

 

Its the right way and neeldes calibrated right so it must be burnt up. Unless other leds are out that are linked to it that I'm not aware of?

 

Only way to find out, pull that LED out and test it or remove it and put in a new one and see for yourself. Usually there is a resistor per each section *about 2-3 per section* of LEDs on the board, so if 1 LED goes out, the others would still operate just fine unless you remove a lot of the LEDs in that series.

Mind showing a picture of how your needles look like in the cluster right now? (When there is no power to the cluster)

 

there are no other leds tied to the low fuel light led. it's an isolated case.
so either the led isn't working... or you installed it improperly.

uh... what?? you mess up one component in the series.. and the WHOLE series won't operate..

"others would still operate just fine".. um... no.

 

....um... when I was testing my gauge out I didn't install the "seat belt" LED (cuz I was debating on white or leave it red) and installed all the other LEDs in that area (series?) those LEDs lit up fine (when you turn the key to the ON position).... so uhhh .... I'd need an explanation about the board Toyota designed? lol

 

a series circuit, is an electrical circuit that is connected in a single path. you break that path.. and the entire circuit isn't gonna work.

a series... IS NOT an area of a circuit board...
a board can have different components wired in series... and be in completely different areas of the board..

there's nothing wrong with the design.. it's your complete and utter misunderstanding of what a series circuit is.

 

nah i knew what a series is, i just misused the word "series" as a portion of the board where a number of LEDs are grouped. I'm no engineer on how boards are designed so do excuse that my verbiage isn't up to par to those who are of engineer levels.

I wouldn't know the technical term, so I'll just leave it as "an-area-of-the-board that-has-a-group'-of-LEDs-near-each-other" and I've tested missing one LED didn't impact the others around it (nor the rest of the LEDs in the cluster), that's all.

Or if you know so well, i'd like to know what that technical term would be so we would not create any confusion in the future.

 

if the leds in a certain area are not on the same circuit... then of course having one missing in that area won't impact the other leds.

it's not a matter of where the leds are.. that's what i was trying to get to. it's just how they are connected onto the board.. as well as what circuitry is controlling them... and if they are on the same circuit or not.

afaik, there's no technical term for an "area of the board"... i think you can pretty much call it that.

since the indicator leds operate individually, they would need to be on its own separate circuit so that they light up when the need arises.

leds that are more wired in series are like the ones for illuminating the gauges.. something that wouldn't mind having groups of leds designed to light up together.

so yea.. the low fuel light is not in series with any other led.. only the necessary components/circuitry to make it turn on when its supposed to.

 

Thanks guys. Yea it was a fried led. So was the "idiot light". Now I need my polarized film to come in to finish these warlocks. Lol
