I have a 1991 honda accord and after my battery died one day all my dashboard gauges stopped working. I checked all relays and fuses and everything was good. So I replaced the dashboard 3 times and I still can't get it to work. I also replaced the ecm and transmission module but again nothing worked. So I moved on to checking all the wires and everything was fine. Then I checked the output of my alternator and it was at 14V so maybe it is burning all the dashboards? If not what can I do because I am out of ideas. Please help thanks.

Check the ignition switch for wear, pitting, or melting--it may be bad.
