Is it a fuse problem if just installed lights on the hood to the turning signal circuit then after a while they and the dashboard lights went out in a '97 Ford Taurus?
Check your wiring and see if there is a bare spot in it to cause
a fuse to blow. Check ALL of the fuses as it depends on what
circuit you got your voltage from.
If the lights you added require more power than the circuit you
tapped into can supply, the extra load blows the fuse.
