Re-wire footwell neon help :)

[kerry-w]

Hi,

I bought some footwell neons from ebay for a dirt cheap pirce, listing said their meant for a PC but can be modified to work in a car.

Here is a diagram of the current wires.

Would the solution to this be to re wire it to like I have done below?

Thanks

yes but the switch needs to be in the postive wire not neg other wise the switch will not break the circuit and be permeantly on

I don't understand? If the circuit has no earth it won't work

[Fulch]

Thats right but the switch doesnt act as a earth. The neg wire to the battery or bare metal on the shell will do that for you.

Here (http://www.allaboutcircuits.com/vol_6/chpt_2/8.html)is the site that made it. Look carefully where the wires are on the battery etc

[adamskiTNR]

But the switch cannot be an earth unless it is in some way connected to the earth of the car. (battery terminal or metalwork)
A switch in earth will still disconnect the circuit. I have wired up many circuits using the switch in the earth feed.

[kerry-w]

Ahh, thanks all, basically just move switch to pos rather than negative :)

Thanks

[Fulch]

Correct Kerry.

Adam, look at my example.

If you dont have the switch on the pos side then all you will get is a constant pos feed to the light meaning they will always be on and drain the battery of its power.

this is the dumbest post ive ever read :wall: dont give advice when you dont know

you can have a positive connected all day long but unless there is a complete circuit then the lights wont be on

so whether the switch is on the positive or the negative side doesn't matter at all :homme:

[adamskiTNR]

Fulch, so your saying that if you disconnect the negative terminal of your car bettery (th same as having a switch on the negative side) your car will still work? Bullshit

[jphni20]

Switch can be on either positive or negative. It still breaks the circuit.

[davidandrews5343]

Switch can be on positive or negative, your diagram will work

Basic electronics IMO, good post

its gotta be a circuit, if you touch the positive terminal of your battery your fine, if you then touch the negative, it completes the circuit and current flows through you back to negative, its a loop, and your fried

Ooo was just wondering what if i was undoing the positive terminal and was holding on to the car frame... would that complete it? would i die?

Yes you would complete the circuit and get a shock, if u had some sort of heart condition then it could be possiable to die. If you were to find out the resistance of the human body and apply it to V=I.R you can work out the current that would pass through you

i would do mine this way and then i know it couldent go wrong :y:

Same... but.... id try and splice into interior light switch, so when you open car door, the footwells iluminate, or you can switch the lights to never come on, if you catch my drift?

would require a fair line of wire to reach up into the headlining mind, but would look awesome


and yeah if you put the negative lead onto the car body then you hold positive while your touching the car, yes you will be shocked, as to the V=IR for humans, id rather not find out ;)

[djgaz9]

well what i done with mine was wire them to the fag lighter and when i turn my side lights on footwell neons come on job done :y:

my footwell neons :)

yeah yeah, looks sweet :P

do they stay on alll the time? (i know you said when side lights are on, i mean when doors are open, or just when side lights are on?)

[kerry-w]

Thanks for the help, im going to wire through to the dash, cut a hole in one of the spare button inserts and put the switch into that, easier for me to control when their on and off etc.

Ohh, one more question, ive got the switches, but they have 3 prongs on them. It is an LED lit switch, so when the thing im using is turned on the LED will illuminate on the switch informing me of this.

Problem is, when I tried it I could figure out how to get the LED to illuminate and get the circuit working at the same time :S this would come in handy for me as im also going to put the AMP on a switch so I can turn that off if I get a headache from it lol

Here is a diagram of the switch -

The + and A prongs are silvery, but the last one on the right is a golden colour.

[Fulch]

Clearly my help was criticised so I wont bother on this thread anymore, sorry.

its not our fault you gave out massively incorrect information...

what are you connecting to each prong? as the switch should illuminate itself when theres power to it (a circuit, witched on)

[kerry-w]

Positive and negative wires, no idea what goes on the 3rd prong though :S

[liam-o]

the A is not the negative, the 3rd one you've labelled gold is the sign for earth

[kerry-w]

A was working fine as the negative I think, hmmm.

Might have been the earth not being connected to anything that meant the LED wasn't lighting then.

[adamskiTNR]

The A is for accessory. I was trying to figure mine out a while ago. In my situation the switch had a double earth so the positive didn't know which one to got to, the light was flickering and the fan was stuttering. So i sent them back and ordered some standard toggles, and i'm gonna get a panel mounted light and wire that into the circuit.

[kerry-w]

Think im getting somewhere....

Managed to get this to work: When neons are off the LED on the switch is on, when turning neons on the LED on the switch turns off.

However, I was it so when the neons are on the LED is on, not the current way. Managed to get this to happen by adding a wire that connects to the positive part of the switch to the earth part of the switch, with the negative on its own on the (A) prong part.

No idea as to why its doing this :S

Any ideas now ive figured this much out?

im not sure if im right on this or if im stupidly wrong... but is the A not for the led so if the A and + are connected to positive feed and the earth is earthed (negative) the led in theory stays on all the time and the circuit is still broken and close with the switch ? may be compleately wrong but hey mite be right for once?

[Gareth_R]

+ is the main power feed for the thing you are switching on. A would be a positive feed for the LED, the gold one is ground, or negative, and will be both the negative for the main circuit and also the grounding for the LED

[adamskiTNR]

The third prong cant be earth for the neons as earth and positive can't run through the same cable. The earth would come off of the neons to ground, with the positive coming to the switch

[Gareth_R]

yeah sorry you're right

tbh that switch is designed for a pc which uses straight forward positive and negative running through the PSU, not a car which uses the whole bodyshell as earth

[adamskiTNR]

I couldn't be asked with them so i just got standard toggle and am buying panel lights to do the same thing.

[kerry-w]

Thanks for the help, loks like ill just use the switch and just have the LED on there broken lol, seems like way too much hassle than its worth.
