Instrument Panel Cluster Gauges not registering

yes...well seen this condition before...what we have here is a failure of the ground from the battery to get to the chassis, where the instrument panel is~ you might check the electrical connections to the dash panel..you might just clean the main ground bolt to the chassis with a wirebrush and get a NEW battery~

i soldered up high watt resister as suggest but instrument cluster still not working only + .9 VDC at power resister. traced voltage to Q58 C collector. after checking circuit found D38 diode had failed, diode was acting like a resistor instead of a diode. After removing the diode power resistors now have +12 VDC now. I soldered in a replacement diode at D38. Put the instrument cluster back in the Tach gauge & blue gear selector display and other gauges appear to be all working now!
