Hi Everyone,
I embarked on replacing my gear shift indicator LCD, it works but the display is extremely faint. Rather than go to LED I prefer to keep the LCD screen and soon discovered the availability of a single digit seven segment display in the right proportions is non existent, however I did find some screens in 3 and 4 digit display with the correct digit size that are cheap and readily available.
I bought a 3 digit display and printed a mount to fit onto the board and into the cluster so only the center digit shows through the window.
I wired it to the board but I can only get a zero to appear. Shifting through the gears it disappears in gear 4 and 5 and comes back on shifting down to 1st. There seems to be 5v at the board and drops slightly I assume when the segment is supposed to not display, I tried adding resistors to lower the voltage to about 3v(LCD operating range) but no luck and this is where my electronics ability have ended!
If somebody can add to this or maybe suggest something that would be great.
