I hope one of you guys can help me on this. When I turn on my headlights, my oil and temp guages as well as my fuel guage start climbing up. Fuel guage reading goes from 1/4 tank to 1/2 tank and temp goes almost to hot. It all goes back to normal a few min. after I turn off the lights. I have checked the ground wires for the lights and have even ran extra grounds from battery to frame, frame to engine and engine to firewall. I don't know if the voltage regulator on the instrument cluster would affect the guages or not as they are separate from the cluster. Thanks in advance.
