suzuki gz250 turn signal problem

[noahgenda]

I am new to this site and am looking for some advice. I have a gz250 and the front left turn signal has very weak blink. The rear signal works as designed. The right front and rear signals work fine. I removed headlight and unplugged the signal wires and generally checked the wire condition. seems like a bad ground, but not sure where to check other than battery terminal. Any suggestions?
