Turn Headlights on Lose half my guages
When my head lights are off all my guages work fine, when i turn them on i lose oil pressure, temp, and tach gauges. Also my turn signal to turn right stays on..it only stays on, on the inside...i can use my blinker still and it works fine. i dont know whats goin on

You have a break in one of the circuit board traces on the back of the cluster. Here's how I repaired mine many years ago - the circled areas are spots where the traces had broken.
Not pretty, but it worked.
