Replacing The Main Fuse - Invacare Tornado Service Manual

7.5

Replacing the main fuse

If the main fuse is burnt out, then this almost certainly indicates a short-circuit in the battery cables.
If the cause is not a battery cable, then there may be a short circuit inside the power module. This
is very unlikely, but can occur under extreme conditions, such as when the wheelchair has been
cleaned using a high-pressure cleaning device. Needless to say, using such a device against
Invacare's strong recommendation not to (in the User Manual) will void the warranty.
CAUTION! Danger of fire!
• Only ever use a fuse with the correct value: ACS System: 50 A, Shark: 40 A!
• If the main fuse is burnt out, then the cause must be fixed before inserting a new fuse!
Requirements:
•
Combination wrench 8mm
•
Spare fuse
•
Large flat-bladed screwdriver
Note
If the fuse holder is damaged, it can replaced together with the battery cables.
Always be careful not to damage or scratch the cover on the electronics compartment, when
using a screwdriver to help open it.
WARNING! Danger of damage to wires and electrical connections!
• If the vehicle is fitted with a lighting system, then always be careful when removing the
electronics compartment cover, so as not to rip the wires off of the circuit board!
WARNING: Danger of fire exists if the fuse is
incorrectly assembled!
• Only ever assemble the fuse in the order shown in the
illustration at right!
• Always tighten nuts to between 3.3 and 3.5 Nm!
• Use the flat-bladed screwdriver to carefully
pry the rear plastic cover off, as shown in
the picture. Remove the cover.
•
Place it aside carefully. The electrical
connectors do not need to be removed from
the circuit board for the lights.
