1986 corvette dash problems
Voltage shows it running high but had it checked out and the voltage is fine. Dash lights don't always come on at first and the dash cluster has some issues. Can this be fixed. 1986 corvette.

A high voltage reading is a symptom of a failing power supply in the digital display. If you are good at soldering, you could fix it yourself by ordering a new power supply from Batee, but if you're not, just send the whole thing to Batee to fix everything. Have them change the light bulbs to LED's and that will cut down the heat buildup in the display. Heat is the enemy of electronics.
