Electrical: Wiring 1963 GT Hawk

[Geohawk63]

What kind of wiring mishap would lead to my left turn signal coming on constant when I turn my instrument lights switch on?

[StudeRich]

You crossed the Bulb Sockets for the Left Turn Signal and the Speedometer Instrument Lighting Bulb Socket.

[Geohawk63]

What do you mean by "crossed"? I certainly didn't remove anything and put it back wrong. Thanks.

[StudeRich]

Someone plugged the Turn Signal Bulb Socket into the Hole for the Instrument Light and vice versa! That would be "crossed' in my book.

[Geohawk63]

That would make total sense if it actually happened! As always I appreciate the input.

I'm presuming you mean the green dash indicator for left turn signal? If it flashes with turn signal, but illuminates steady when parking lights are on, it's usually due to the front park/turn signal not being grounded.

Yes but it illuminates when the instrument panel light switch is turned on, not the parking lights.

If your Instrument Lights and Instrument Light Switch are properly wired they connect to the Headlight Switch Terminal that is Hot whenever Either the Parking OR Headlights are on ONLY, that is where the Tail Lights are also connected.

So NO instrument lighting without either Parking or Head Lights.
That makes me wonder just HOW original and correct IS this Hawk?

Geohawk63 Gotcha. I'm a bit stumped without more symptoms. If it was a bad ground up front, the turn signal indicator would illuminate steady when park lamps are on, independent of panel lights; it would probably flash with turn signal, but the parking light element up front would flash instead of the brighter one.

So, does the indicator dim with your panel lights? Does it flash with turn signals, and are turn signals working normally?

Yes that is how it is all wired. So strange but it has fixed itself now!

Very likely a loose, poor Ground on a Light; Tail Light, Parking or Dash Turn Indicator Lights, it WILL be back!

Haha you bet it will!
