trouble with the hood mounted turn signal

[goldmach1]

70 mach1 when the headlights are on or even just the park lights my right turn signal indicator on the hood stays on (very dim). I have 2.4 volts coming thru at the plug in under the hood. I can't seem to find anything on the wiring diagrams about the turn signal indicators on the hood. Can anyone give me a starting point on how to find this voltage bleed thru thanks
