Sir what is the solution for fuel and temp gauge not working properly? when i open the grounded headlight at night the gauges going up at their middle point, for example in engine temp the real temp is 1/4 if i open the grounded headlight it became 3/4, also in fuel gauge for example its 1/2 fuel if i open the grounded headlight it became full.... what should i do if i fix it please help i'll do it by myself,, tnx for understanding
