A while back, I posted a picture of a front light harness, showing where the "Ground" rings were, basically,you need to get an Ohm meter, and check the continuity of the connections in your front light harness.I had a head lamp wire that was grounded and blowing fuses, so, I unbolted the front light harness and engine harness from the firewall (7/16") once you unbolt the harnesses from the fuse block, check the continuity of each wire, end for end, make sure you have no breaks (no readings on the meter) most meters will have an audible "Beep"
If the continuity is good, otherwise, the scale will read "infinity" (maxed out) if not, you have a break.
But keep to keep it simple, check the ground wire back to the fuse block connection, I'll bet you have a break in the ground wire, or it's contacting one or more of the headlamp wires, light green or tan.
The dash cluster has it's own ground, a single black wire with a clip that attaches to the dash sheet metal behind the dash. It is possible that the turn signal switch got damaged during the collision, as if someone may have hit the steering wheel, just a guess...but my guess is that you have a wire or two that got pinched in the accident. Hope that helps... the bottom picture shows a chrome pointer pointing to a ground lug, this is located near the voltage regulator.
