hahah....i cant seem to find my fuse box....i havent lost it or anything :lol:
basically...it all started when i tried to do a mod with my boring flashing red LED on my drivers side door. i was trying to replace the red LED with something more :funk: BUT i seems like i may have short circuited something when i cut the wire, as my mate tested it with a voltmeter and got nothing :( so i basically need some good advise as to how i can find out whats wrong, and if possible for any electrical boffins out there to tell me what LED and What Resistor i need to buy for it to work!

by the way the original LED and resistor were destroyed in the process so i cant tell you the type of resistor or led! :(

please help :confused:

fuse box is on the right hand end of the dash. open the door and youl see the flap you pop off the end of the dash

your fuse box is in the side of your dash board. if you open up the drivers side door theres a bit of plastic you can take off with a screw driver on the vertical part of the dash board. only know its there when the garage was trying to find the diagnostic switch, they opened that part up by mistake.

go to Maplin's and get a 12v LED in what ever colour, size, blinking or what ever you want. then you don't need a resistor

assuming that the supply to it is 12v as you have shorted it and can't tell

pay someone to fix it and tell them u where silly and wanted chavy lights. Therefore should pay them a stupid amount of money.

Yea a 1k resistor is required, worked it out from my physics knowledge and crocodile clips.

Just to show how I worked it out

On crocodile clips the current through the resistor is about 10mA

So the voltage across the resistor is calculated by current x resistance

(10x10^-3)Amps x 1000 Ohms = 10 volts

Therefore

That 10volts taken away from the 12volt supply = 2volts across the LED which they can normally handle, plus it didn't blow on crocodile clips, and its a very accurate program.


Sorry about the physics lesson :happy:
