I Broke It!

[FuntimePhil]

Attempted to do my lights on the ac unit tonight. thought it was fairly simple. wire-resistor-led-resistor-led etc etc. but i realised that i dont actually know where i was going to connect the wires too?? so i just touched the wires on the contacts where the bulb was originally, its sparked and now its all broke!! and constant kicks out hot air!!

Please help

thats bizare

1st things 1st

did you put the dials back correctly ?

You must have had a short somewhere mate,

Do you mean you had the LED's in series? i.e power-resistor-led-resistor-led-etc-earth?

Or in parallel? i.e each one power-resistor-led-earth?

If you had them in series that wouldnt be good. You may have had a short somewhere as well (ie the leds touching each other or a live directly to earth. but if its pumping hot air its probaly goosed mate sorry.

Quick edit: when you tested it, did you put both plugs back in? only one and it will blow hot air.

This should explain what i mean:

i dont know haw to do it the first way, i followed the instructions you sent me. i think its blowing hot air cus i left a pin out, i have just found the metal contact on the floor whilst cleaning up.

where is the power connected to anyway?

[sparkystav]

The first way is the way the walkthrough i sent you tells you to do it. if you put them in series then you wont get any light out of them.

And by pin, you mean the one behind the knob, that runs along the tracks? their fiddly little buggers i've lost a couple in my time lol

[FuntimePhil]

im well confused now. if each LED needs its own 12v feed and say i have 20 bulbs in there, does that mean thats 40 lots of wire i gotta run?

or do i just put a resistor on every LED. connect all the resistors together and connect that wire to the power?

[FuntimePhil]

ok i did a search on connecting in parallel so im happy with that now, although the tinterweb says you only need one resistor in parallel, at the beginning of the circuit. but anyway, where are you connecting the positive and negatives?

[sparkystav]

You can put one resistor but i'm not sure what size it should be, or howmany you can connect to one resistor.

But you were right before you can connect all the resistors together and then one wire off them.

And you were right the pos and neg need soldering to the contacts where the old bulbs were.
