83 240D Instrument Cluster Lighting/function goes crazy when lights on
 

On my 1983 240D, my instrument cluster goes crazy when I turn on the Lights. The Turn signals come on, The temp gauge goes max and the fuel gauge goes off. I took out the Clsuter and I looked at the Section with the Printed Circuit Board. Some of the Circuit paths are damaged, the printed copper paths are frayed or broken. Is there a way to fix it? I tried to hard wire the path, which ran to the turn signal. The thing still acts crazy. Any ideas? I have nothing to lose-------------
