Okay. I am determined to finish this install this week, but I need some help. The wire that comes off the LED's on top of the R shroud (top four LED's for front lighting) needs power. Now the wire is extremely thin, which makes me wonder about 12 V being too much and overheating something or melting wires. Does anyone know for sure how much power runs through this wire to the LED's? I need someone with VIDA help to set me straight so I don't destroy this thing due to my impatient nature and lack of knowledge. Thanks in advance!<p>-Adam<p>The wire in question...<p><A HREF="http://www.hostdub.com/VRSixRado:12Rlightwire" TARGET="_blank"><IMG SRC="http://www.hostdub.com/albums/VRSixRado/12Rlightwire.sized.jpg" BORDER="0"></A><p>The LED formation on the guage shroud...<p><A HREF="http://www.hostdub.com/VRSixRado:11Rtoplights:full" TARGET="_blank"><IMG SRC="http://www.hostdub.com/albums/VRSixRado/11Rtoplights.jpg" BORDER="0"></A><p> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: I.D. a wire for me, and voltage if possible... (S60Driven)

LEDs use less than 0.040A and a string of them can be in series and use that same 0.040A.<p>Each LED has a 1-2V drop across it and a series resitor is used to set current level. The V drop depends upon the type of LED, Gallium Arsenide etc etc.<p>That wire is A-OK<p>

Re: I.D. a wire for me, and voltage if possible... (JimLill)

Thanks so much for the info, Jim! Forgive my lack of understanding in this subject (this is my first time working with LED's). So you are saying that running 12 V through that wire will be ok? What gauge wire should I use to connect the wire off the shroud to a power source?

Still working on that R console in your T5? Quite a project you've gotten yourself into!! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">

Re: I.D. a wire for me, and voltage if possible... (soledoc)

Yeah seriously...but considering the 70 hour work weeks, I get about 2 hours a week that I can actually put into my own hobbies/free time. Tonight I have a about 3 free hours and I am determined to finish this. Got the rest of the plug in LED's I wanted so I should have updates tomorrow, depending on the issues I am having with powering the LED's in the shroud.

Re: I.D. a wire for me, and voltage if possible... (S60Driven)

you need to measure their resistance.... in both directions... it will be very high in one and low in the other. Report your findings here........

Use this calculator:<br><A HREF="http://www.quickar.com/starresistorcalc.htm" TARGET="_blank">http://www.quickar.com/starresistorcalc.htm</A><br>The problem will what supply voltage to use. Use 12V and risk bruning the LEDs when the engine is running (voltage jumps up over 14V). Use 14V or higher and the LEDs might be too dim when the engine is off <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0"> Maybe do a test using supply voltage of 15.5V to be safe and see how it goes.<p>Or, use a voltage regulator and have your cake and eat it too (probably a 5V or 9V will do the trick).<br><A HREF="http://www.eidusa.com/Electronics_Voltage_Regulator.htm" TARGET="_blank">http://www.eidusa.com/Electron...r.htm</A><p>LTA<br>

Re: I.D. a wire for me, and voltage if possible... (S60Driven)

S60Driven,<p>Would you do me a favor and take a picture of the R gauge cluster with the face piece removed? I am considering installing a custom LED turbo meter and have no clue how much room, if any, there is behind the face. Also, was it easy to pull the shroud off to get the gauge cluster out?<p>Are you still planning to use the T5 carcass and simply transplant the visible parts from the R's cluster? I sincerely hope it goes smoothly given the headaches it has caused you thus far.<p>Best of luck to you on the swap. <p>- Tryg

Thanks needsdecaf,<p>I don't frequent the S60 forum enough. Those R gauges sure are pretty, especially next to the T-5 set.<p>- Tryg

Re: I.D. a wire for me, and voltage if possible... (needsdecaf)

S60Driven,<p>I'm still curious as to the difficulties of removing the shroud and cluster. Seeing your post in the other forum has me wanting to investigate my LEDs to see if I can rectify the dim spot on my speedo bezel, as well as the disparity between the backlighting on the odometer and clock displays. Blue or red lighting for the displays would be a nice touch, too, while I'm in there.<p>Please let us know how your project goes this evening! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <p>- Tryg

Re: I.D. a wire for me, and voltage if possible... (RainyS60R)

Rainy, <p>Removal is extremely easy. Just take your time and you can do no wrong. Just be sure to disconnect the battery befory doing anything. Follow my writeup on the link and its as simple as that. <p><br>Update:<p>Ordered wrong LED's. That's gonna tie this up a bit. Still going to try and get the front lights working tonight. We'll see. <p>-Adam<br>

Re: I.D. a wire for me, and voltage if possible... (S60Driven)

I was actually referring about the panel (shroud, whatever) that is part of the dashboard (leather-wrapped on the R). Does this part need to be removed to get the cluster out of the dash?<p>Thanks in advance - Tryg

The plastic surrounding needs to be popped out then the rest is self explanatory. You don't need to do anything with the top part of the dash. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
