Car lost all electrical while driving

I noticed my dome light wasn't working and I put a new bulb in with no change. Found the fuse to be blown. Do you think its a coincidence from my recent electrical shutdown when driving or is it a symptom of the problem I had?
What else is on that fuse? and did anything other fuse burn out?

It's possible that its related.
Dome light circuit works like this.

main splice------->fuse-+-------> Dome light--------+-------> door switch-->ground.

There is always power to the dome light. Any door switch can complete the circuit to ground.
The headlight switch can also complete the circuit to ground.

The only reason for the fuse to blow is if the wire(s) between the fuse and the dome light shorted or grounded.
If it grounded after the light, the bulb would have lit up.

'67 that fuse is shared with hazzards, brake lights, and parking lights (B2 terminal on the headlight switch). '70 may be different. Need to look at the FSM and color or sketch connections. Owners manual will have the cliff notes version.
