I am getting electrical feedback when I turn the headlights on. It makes the left turn signal dash indicator glow green. It only happens when I turn the headlights on. I also noticed the left turn signal isn't quite as bright as the right. I have a new forward wiring harness and new engine harness from H&H. It seems like it's a ground problem but I have checked the connection many times and also removed all the paint where the harness wire grounds itself to the core support. My water temp gage doesn't work either now and it used too. I have the correct sender for gages also. If I use a test light and ground the water temp gage out at the sender, the gage then moves. Can anyone think of a ground I may have forgotten? The engine has the ground strap to the firewall also.
