Start the '69 Superbee and everything works great. Then, turn the headlights on and the qauges go dead and there are no lights on the gauges. However, the lights on the clock and the left side of the speedometer do come on. It used to happen intermittently and when I hit a bump everything would come on. Now only the clock and speedo work when the lights are turned on. Shut the lights off and the gauges start working again. What's up with this? Is this a bad ground somewhere?

You say run a ground wire up to the dash frame. I should run a wire from where to where. Keep in mind this thing has a printed circuit. Thanks

I got up under the dash with a light and started tugging and pulling on the light switch wires and the light bulbs and all the wires going to the gauges and everything started working. However, I'm sure it will happen again especially if I hit a bump. Although every time in the past, it only happened on start up. Does this still sound like a ground?

Sounds like you need to track down the wire that supplies power to the affected lights and fix the short.

Andrew:
You helped me once before and I'm looking to you once again......
I tried posting this question on the forum but can't get in.
It's a 69 Superbee. Completely restored 9 years ago. All new wiring through out. The problem started about 4 years ago and then corrected itself. This weekend it reappeared! Now when the headlights are on the green directional indicator lamp on the right side of the dash and the fender mounted turn signal stays on constantly ( doesn't flash). The green light stays on. The left side works perfectly ( no problem). When the right directional indicator is turned on.........the lights flash as they should with the headlights on or off. This only happens when the headlight switch is turned on. Any thoughts?
