1992 Nissan Truck Battery Dies

Suggested Repair
Confirm the battery is fully charged and correctly rated, and tighten loose battery and charging-system connections. Check for a parasitic drain and test fuses with a 12-volt test lamp; the dead dash and heater blower are likely low-voltage symptoms, not the cause. The alternator tested good.
Conversation Summary
A 1992 Nissan 4x4 pickup with 153,000 miles started after sitting, then repeatedly went dead in very cold weather after the lights were left on and short drives. The alternator tested good and the belt was tightened. The expert attributed the issue to cold weather, loose connections, battery drain, and possibly an undersized battery or parasitic drain rather than a blown fuse, and explained fuse testing with a 12-volt test lamp. The dead dash and heater blower were described as symptoms of the electrical problem.
