1990 Honda Civic

Got A question, Wondering if anyone might have a good answer. My car is doing some wierd things with lights. When i'm driving at a good speed 80Km / 55m or more, when i put my blinkers on, the heat gauge and the RMP gauge dump when the blinkers light up. When i put my highbeams on, the RMP guage goes crazy. also , my gas guage says i'm full... but i'm not... Any idea, let me know. Thank You VERY much.Here I Am.

ewwww A ghost in the machine question (ghost in the machine-when the machine seems to have a mind of its own and no longer functions as instructed)

There is definatly an electrical problem, but unfortunatly there is no way for us to solve this online. You will need to take your car to a Automotive shop that has an ASE certified automotive electrical systems technician. He will be able to exterminate your ghost. EDIT: Or you could drive state side, and into fremont ohio and I'd be more then happy to trouble shoot it for you.
