Hi,

can someone please help me where to connect +12V, GND and K line on this dash?

Here is the picture, just to see which one it is, I suspect its all on that red connector.

all gauges and some lights are not working, so I suspect on L4938N double voltage stabylizer, but need to connect it to power supply to test it (don't have car to fit it in and test, and also it's much easier this way).

Thanks!

voltage stabilizer works ok, but discovered something wierd:

when i connect +12V to pin7 of the green connector, i get backlight of the LCD screens, which i didnt had when dash was in the vehicle, but when I add +12V to pin11 of the red connector, i get main backlight, but previous one shuts down.

any clue what to check next?

lookl like microprocessor is not getting any "wake up" signal and is shutting off everything else.

how to find out what tells microprocessor to enable instruments?
