Ive had some questions about how i changed the LEDs. since theres a lot of different types of guages (it seems that the handful of people who have done theirs all had different gauges)...mine will be in refrence to a 2006 S2R1000 guage, which in my own observation looks very similar to the S4R and S4Rs guages. The S2R and 695 looks to have a slightly different one. you will need a total of 10 PLCC-2 LEDs of your color choice. I used 800mcds, you may want to go up to 2000 if you want it as bright as the orange LEDs. you can change the brightness of the gauges by turning on the bike and immediately pressing hte LO temp/Clock button. your bike does not need to be on. WEAR SAFETY GLASSES, you can get solder in your eye while using your perfer method of desoldering these leds. and it probably wont be fun.
1) Unplug your gauges
2) remove the screws on the back of the shell there are 5 of them dont forget the one on the very bottom. of the gauge.
3) the front of the gauge and the circuitboard should now lift out. Becareful here, its a perfect fit, so dont wedge it, it should come straight out.
4) Turn over the face of the guage and there are a few clips holding the front of the gauge to the circuit board and shell. go ahead and unclip the board.
5) you should now have a white plastic frame with a circuit board underneath and the gauge face on top.
6) lift the edge of the gauge face and use some sort of ink to mark the needles zero point. You want to get the ink on that metal rod thats holding the needle. This is just incase you end up twisting the needle while you remove them.
7) grasp the center of the needle with 4 fingers (ithelps to have small hands) and pull straight up. you basically want to pull your fingers toward your palm. the needles should pull straight out. If you accidently turn the needle while twisting, then your RPM/MPH will be screwy now, but its okay since you marked the zero point.
once you remove the needles you can remove that plastic frame, there are 4 clips on the back of the circuitboard, 2 on each side.
9) go do your soldering thang
10) when you reinstall your needles,take the board and plug it back in, let the bike reset it to zero and put the plastic covering back on it as well as teh gauge face. make sure that black mark is now lined up. ( you find that the needle is a bit hard to turn after the unit is powered on) install the needles gently and turn the bike on to make sure it sweeps and comes back to the right place. after youve confirmed it does (or have corrected it) presss the needles down and close her up.
On the S2R800/695 it seems that the needle isnt a one piece design, and instead is glued onto another plastic piece that connects to the motor. On other gauges it also looks like you have to open that center panel on the front of the gauge to take it apart. your guages may be different if they are not S2R1000 gauges.
Here is how i desolder them, there are numerously better ways to do it, but this one was easist for me. do note, its very possible to damage the original LEDs this way, i got lucky, and im going to use them in my plcc-2 led rear tail lights! i was using a 15watt soldering gun, and the solder solidified pretty quick so i couldn't just melt both ends and remove the LED and i got into an arguement about with the dude at the radio shack so i didnt feel like going back there to pick up a vaccum pump. as far as soldering goes, im gonna assume you already know how to solder.
Desoldering Ducati Monster Gaugesthere are the guages on MAX brightness, they turned out quite well, these are 800MCD PLCC-2 LEDs, they have 2500MCDs, and if i had to do it over again, id probbaly use something above 2000, so i can adjust the brightness of the thing.
SDC10494thats all there is to it. any questions feel free to ask.
I also found this nice link to the older style gauges.
