TEST
Before replacing the battery pack, ensure that the two fuses (1) are in good electrical working order
by removing them from the fuse holders (2) on the left side of the battery pack (3) and testing for
continuity with a multimeter. Continuity through the fuse ensures that it is in good electrical working
order. If there is no continuity through the fuse, replace it with a known good fuse from the on-board
spare parts (4) located at the inlet end (5) of the heater. If the fuses are both in good electrical
working order and the battery pack is not supplying power to the heater, replace the battery pack as
detailed below.
