    Default NS/AS/RS Console Backlight LED color swap and Battery voltage monitoring.

    Hi,

    So my objective was to change the backlight of my AS200 console from orange to blue. Was a blue backlight fan since RTR160. Also the switch cluster is of blue color, I feel it doesn't match pretty well.
    So went through some threads in xbhp to get a rough idea of what LEDs are used inside.

    Analysis of console:
    The LEDs for needle and tachometer is 3528 SMD 0.2W amber and Red colored.
    Since needle is red I don't wanna mess up the colors.
    The orange for the tachometer reading needs to be swapped with cool white.

    The LEDs for the LCD is 0603 amber ones 0.1w each.
    I needed it to be pretty bright so I went ahead using a slightly larger die chip.

    Next large die was 1206 SMD LEDs.

    Things required.

    Desired color of LEDs
    3528 and 1206 LEDs least 20 numbers each. SMD soldering can get messy at times. So some spare LEDs can be handy.

    Micro soldering station. Soldron brand is recommended due to better temperature accuracy.
    Can also use cheap SAMCON brand does the job well.

    Hot glue gun. To fix the voltmeter and lcd terminals.

    I'm not much concentrating on the dismantling part as this is already covered in the old thread from Xbhp.

    Good soldering experience. This needs patience and lots of experience in terms of desoldering and soldering back.

    Note: I'm not using desoldering gun. I'm using desoldering wick to desolder the LCD from the PCB.

    Use 35w soldering for desoldering using the desol wick.
    Note: dipping the desol wick in liquid flux will help the capillary action of the wick more effective.

    Desolder the amber LEDs from the PCB. Mark the polarity of the LEDs.

    I'm using cool white for the tachometer reading 3 LEDs.
    And blue for the LCD display 8 LEDs.

    If one needs he can also swapout the telltale lights LEDs and rev limiter LED color.
    I personally like Red is the right choice for revlimiter. So went ahead with it.

    A closer look on the PCB.

    Resolder with ample flux such that no dry soldering occurs.
    Since vibration and dry soldering doesn't work well.

    Now onto the voltmeter or battery voltage monitor system (Fancy techy name).

    I bought these cheap 3 digit voltmeter modules off of AliExpress long back. One can use the blank space in console where the Bajaj blue logo is present (Bajaj Bluetooth Logo).

    These LED voltmeters are available in various colors one can match the respective LCD backlight color he goes to.

    The white plastic frame can be cut to the desired size to accomodate the voltmeter.

    There has been significant changes in console of 2012 to 2013 NS and post 2013 NS since more tell tale lights have been added. the number of pins are higher in newer models.

    20pins on the newer ones.
    16pins on the older ones.

    For voltmeter negative one can use the PCB ground as negative input for the voltmeter since the Voltage regulator ICs use the PCB ground as a shared negative.

    Will share the exact pinouts for both old and new models soon.

    Place the voltmeter and use hot glue to fix it in place.

    Check for functionality before reinstalling the LCD in place.
    Note : never pry or apply too much force into LCD display since it's glass and very thin it is prone to shatter.

    Resolder everything back.

    Final output.

    Note:

    Since there are threads on dismantling I don't wanna pin point the steps on how to dismantle stuff.

    I assume if one is experienced in soldering he knows how to dismantle the console.

    Same procedure can be done on any bike.

    Get to know about what LED is used by just googling out. All LEDs are dirt cheap from AliExpress.

    Also I'm adding in a BS4 NS200 ABS bike's console below just for comparison purposes (just to show the even lighting on the LCD display)

    Update for NS200 BS4 ABS users.
    There is been an update on the console in-terms of LEDs

    So plan accordinglyName:  IMG_20200328_113720.jpg

    All 3528 LEDs are of quad terminals with pin 1 and 4 being positive and negative.

    So when buying LEDs plan ahead
