Default Electric malfunctions

So far it’s running well! But sometimes the hazards go on randomly and the dash lights go off for half a second. Also the lights for the temperature get all funky and look like alien language. Should I redo the wiring system throughout the whole car??? Where should my head be during this part of the restoration process??

Definitely don't redo the wiring. Likely issues are bad connections between the mother and daughter boards in the dash display. Check your grounds too. There should be no voltage between the negative post on the battery and the frame or engine. To learn about display issues check out Batee on youtube:
