LCD backlight
I fixed the lcd polarizer issue on my 90 coupe and now I'm not sure if this is normal or something is off. When I start the car the LCD backlight is at full brightness during the initlat test but then the lights turn off. The only way to get them on is to turn on the parking lights or headlights. It makes reading the screen during the day difficult, is this normal or is there something that needs to be replaced?

The backlight should be full bright at key on, and bright with the lights on. Otherwise, it automatically adjusts brightness from the sensor. On the Digi-dash cars, you can twist the headlight **** to the right to increase base brightness for the gauges, idk if there is a way to do it on the 2nd gen interior.

Thanks for the info. I'm fairly sure you are right about the sensor being faulty. Yesterday I did test its resistance while i had the DIC out. Although i dont remember the values there was a difference from completely dark, room lights and direct sunlight. I contacted Batee to get reference info on the sensor, once I get that I can see if it's a faulty cell or bad connection elsewhere.
