I came across something interesting during one of the console mods I performed the other night. When replacing the resistor in series with the clock LEDs, they ended up too dim. After doing some testing I figured out why. Due to tolerances in circuit components, the regulated voltage on that particular board was 7.90V as opposed to the 7.95V I have seen on other boards. This may seem in-significant, but the LEDs drop right at 2.643V each, adding to 7.93V. So simply replacing the resistor with a jumper allows for just enough voltage to power the LEDs and make them bright enough to illuminate the clock as long as the power supply is providing more than 7.93V. So, in the case of the one I mentioned the 7.90V causes major dimming issues. The LEDs barely light at all.
So, I added a quick fix, which is basically the same design as the other groups of 3 LEDs. I performed the following:
1) Cut the trace between the first LED and the second one.
2) Connect the Cathode of the first LED to the Cathode of the 3rd LED using a 680 Ohm resistor
3) Connect the anode of the second LED to the anode of the first LED using a 330Ohm resistor.
This actually came out a little brighter than needed, but looks great. I may raise the value of the resistors to around 800 and 430 to make them match the odo a little closer.
So if anyone comes across this issue when trying this mod, this is why. I reccomend doing it this way the first time to avoid repeated disassembly and assembly. I will post pics of the next one I do this way to make it easier to follow.

Thanks
Thanks
Not yet. My girlfriend and her son moved in with me last weekend from OK. So we are unpacking, re-arranging, etc. Plus I have had one hell of a hard week at work and have done 2 gauge and console conversions with one left to go today.. so my week has been tiring to say the least

Check this out. It looks like there is another way to fix the dim blue/white console problem. This was on clubsciontc. Heres thie link to the topic, its on pg 12: Courtesy of Viro!

Have you seen this engifineer? What are your thoughts on this and do you know where I can get these bridgable jumper cables?
