Turn Signal Indicators Glow when Park Lights ON

I am in the process of getting all the bugs out of my 71 Demon 340 after repaint and reassembly. The turn signal indicators glow when the parking lights are on. Turn signals and park lights all work. I'm thinking a less than good grounding of the instrument panel is the most likely culprit. I did repaint the dash housing before reassembly. Anyone had a similar issue and resolution?

Thanks,

Mark
