I don't have an owners manual for my Japanese born HDJ81 and have a question about the green and red lights on the dash on either side of the word "turbo" in the center of the tachometer. Picture attached. While driving the truck the green light is lit, have never seen the red light lit except when the key is in the On position without the engine running. I assume green being lit is normal and indicates the turbo is OK- and if the red light is lit there is a problem- is this correct. Any input would be appreciated, Thanks!
