Thanks for your help Breckinridge that led me to a post that told me to check my charge lamp relay. Sure enough the relay is no good. So now I just have to see if my alternator is what caused the relay to pile up
I have a 86 land cruiser diesel. The orange filter light, the park brake light and the battery light come on. Once in a while when I drive down a rough road all those lights go out and every thing is normal for a while. Then the next time I look at the dash those 3 lights are back on. Any help...
