Reverse glow gauge buzzing sound
 

O.k. So I just installed my Alfa Otto silver reverse glow gauges as described in a previous thread for titanium gauges.

Excellent thread, they work. HOWEVER; I have a power? switch with two color choices, blue and green and a low to high turn knob.

Power/Color Turn Knob:

Whenever I turn on the Blue color I hear a high pitched buzzing coming from the black box (power source?) that sounds like I'm gonna get shocked soon. (Green has a low, quiet noise also-less scary).

Blue Noise (ignore the scratching):

I tapped the black wire into a black ground wire and the red on to the green wire with the red stripe on the big cluster on the right (as described in the old thread).

WHAT DOES THIS MEAN?

Too much power for blue? Have I tapped the wrong wire? Or is the wiring itself broken?

Can anyone out there help me?

Thanks in advance. [/align]
