[Heavy7]

A while back i wa driving along, and my dash lit up very bright and the generator light came on, car seemed to shudder and stall for a quick moment, i lost all the guages fuel guage was reading incorrectly as well. It is a rally guage with tach on a 69 gto. if i put a ground to the back of the printed circuit, it seemed to make the guage sticks move a bit. i replaced the headlight switch and the high beam switch, i also had the cicuit board repaired, as it seems to have blown a couple of the brass wires to make the circuit. some say the horn relay causes some electrical issues?????. all ground straps are in good shape. Is ther a resistor somewhere in the harness that i cannot see?? New circuit board is in the mail, but i would hate to put in in and have a reoccurrence. Any suggestions as to this problem would be great. Thanks....Ryan in Canada
