Turn signal wire problem
 

Wondering if someone can help with electrical problem that I am having. My turn signal is not blinking when turned on. The bulbs are lighting steady only. Turn indicator light turn on than both left and right dimmly lit up. But if I replace blue/white wire on the back of tach with wire to ground, the turn lights and indicator work normal except that the turn signal relay buzz like crazy. Can anyone help?

you got a bad ground connection. proof is the feedback to the guage. clean/check all related ground connections.
