If low voltage is detected in a number of circuits, do a voltage drop test across the battery terminals, and engine/body ground straps. I'd always suggest swapping the fuse out for a test and not just checking continuity. If the properties of the fuse wire e.g. Yes, it may show continuity, but the fuse can open under the current load of the heater.
