I have just spent four evenings trying to get the indicators working on the (1985 110 CSW) Clumber Spaniel Wagon. The hazards worked OK, so I knew it wasn't a problem with the wiring to the bulbs or the flasher unit.
I changed the hazard light switch. No effect.
I measured the voltages on the fuses, all what I was expecting and no blown fuses.
I mapped out the Haynes wiring diagram (it would be nice to know what's the connections inside some of these boxes e.g. hazard light switch).
I then removed the steering wheel and the plastic covers to get good access to the indicator stalk.
No 12v there, but there was 12v when the hazards were on, so a missing
12v from the fuse box.I checked the fusebox again. All fuses intact, all at 12v.
I took the battery off then removed the fusebox to have a better look. All the wires looked OK, but low and behold, when the battery was re-attached, all sprang to life.
So, the fuse holder was OK, just a crap connection to wire behind!
Mutter, fusebox, grumble, mutter, mutter!
Are there any blade fuse replacement/equivalents for the defender?
