Lost all electrical power? 73 C30

[TheCougarine]

I'll have to check that out as I've yet to find a fusible link thats burnt up. I did have an odd thing happen today though. While looking at the truck today I suddenly noticed the dome light had come back on so the cab had power, unfortunately turning the switch on killed the power again. Turning the headlights on would also kill the power. Since then I've not been able to get the dome light to come on again. Am I looking at some kind of short somewhere possibly?
