Dim Dash Gauge Lights - Only 10.5 volts to Headlight Switch
Need some help with figuring out why the hot wires (Red and Orange) on the headlight switch for my 68 Firebird are only supplying 10.5 volts to the switch. The issue I have is with dim dash gauge lights. I have already replaced the headlight switch and checked grounds. Car was rewired with a Painless wiring harness about 15 years ago. I started having this problem about 5 years ago. It seems to have gotten progressively worse since then. Thanks in advance.
