I have an '84 300 Turbo Diesel. Love it, but I don't have an owner's manual.
I have a warning light intermittently going off on the dash. It's a circle with 6 dashed lines around it. I seem to notice that it might come on when I hit the brakes hard, and at times it will just kind of flicker off and on for no apparent reason.
Anyone know what the warning light is for, what problem I may be having and how to fix it?
