Relay Box: Description and Operation
FUSES AND RELAYS
General Information About Fuses
The car's +12 V power supply is fed to the various items of electrical equipment via three main fuse boxes, one in the dashboard, one in the engine bay
on the bulkhead partition and a Maxi fuse holder in the engine bay behind the battery. Most of the fuses and relays are located in the main fuse box.
The fuses are of blade type and, together with their connecting sockets, result in a lower voltage drop than earlier types. They are also more resistant to
corrosion.

Checking Blade Fuses
Checking Blade Fuses
Each blade fuse has test sockets which can be used to check that the fuse is intact without the need to remove it. If both sockets are live, the fuse is intact.
On a fuse that has been removed it is possible to see whether it has blown.
