Headlight/tail-light/fuel light/speedo needle flicker: FIXED

[DucHead]

As the Subject line says, my headlight/tail-light/fuel light/speedo needle "flicker" when the bike is running.  I checked the battery terminals and the electrical connections to the gauges, headlight and tail light.

Any ideas?

Otherwise, the bike runs fine.  Some popping on decel, but perhaps caused by newly installed pod filters combined with high humidity.

Wire to negative battery terminal connected but very loose.  Note to self: check electrical connections with my eyes and my hands.

Loose fuse?

I'll put checking the fuse box on the list, thanks!!
