[xj] Inline Fuse on bulkhead in Engine Bay

Chaps,

I have an inline fuse and holder on the bulkhead in the
engine bay - its on the drivers side ( UK car, rhd ) near
the master cylinder. It contains a 17 amp fuse. It has a
brown cable going to it.

Nearest thing I can see in the handbook is a ‘horn’ fuse
listed as ‘on the bulkhead’ - but the horn still works with
it disconnected !.

Any ideas what circuit it is for ?

Series III car?

Yes, it should be the horn fuse. One wire brown, the other
wire brown/purple. My guess is that someone has been in
there and done some wiring changes [shrug]

I agree with Doug, it should be the horn.

I wonder if the fuse failed sometime and someone has connected the
switch (in the steering wheel pad) directly to the horn by fudging
the connections at the relay. So the switch operates the horn
directly instead of switching a relay?

It might be worth checking the connections to the relay which is
inside the right wing below the air filter near the fuel injector
resistor pack. It should have four connections. 2 thin wires, which
are the switch circuit, and are connected to the relay coil. 2
heavier brown wires one of which comes from that fuse you’ve found,
the other goes to the horn. The latter are connected to the relay’s
switch contacts.

Regards,

Andy–

Thanks for the replies, you where pretty much spot,the
inline fuse holder had fallen apart internally and someone
had run a new +ve wire to the relay !.
