When i turn on my headlights the fuel gauge goes to empty, the dash lights do not come on, and the directional indicators both of them flash when you turn them on. When the lights are off every light works correctly and directional indicators work properly. The car was changed from shift lever on the column to floor and the backup light switch is unhooked. the neutral safty switch is unhooked to. Any ideas will help. I did change the headlight switch but that did not help. Thanks.
