Hi Guys,

Lost the lights in my dash and glovebox. Checked the fuse box and the 10amp fuse has burnt out. Replaced the fuse and same thing happens every time I turn the lights on.

Any ideas? Am I looking at having to take the dash out?

Took some pics of the fuse box and some loose wires I've got hanging out from under the dash.. not sure if this has anything to do with it :/

I had an incident with the glove box light.
Filled the car up with smoke and blew the fuse disabling the windows so I had to make an emergency stop to open the door to let the smoke out!!!!

Sounds like you've got a short somewhere.
Thiink mine was the switch on the glove box door.
But with these alfas it could be anywhere!

Good luck.

Hi,

It could be a tricky one, because that fuse supplies at least seven circuits (depending on counting),
the dash and the glovebox lights only two of them.
Other related lights to this fuse:
- Cigar lighter's background light
- Ashtray light
- Clock backlight
- Heating/ventillation panel's background lights
- Number plate lights
- Front and tail left + right side lights
also connected to the "lights on" warning signal

You can try to disconnect the mentioned circuits, then check for short curcuit
at one terminal (which is not powered) of the burnt fuse and ground.
If the short circuit persists then it's probably an insulation failure.
Otherwise reconnect the circuits one-by-one and repeat the short circuit test.
Without a multimeter it will cost a lot of fuses to find the shorted section.

The "loose" grey(ish) wires are related to the (factory) front right speaker.
The wires at the top of the fuse panel (near the 25A fuse) are related to the fusebox / footwell lighting.

I hope this might help.

P.S.: An RHD 33 on Malta?

Hi,

In this case no relays are affected, but most of the circuits/consumers have their own connector
within the wiring loom. I meant disconnecting the relevant consumers directly or the connectors related to them,
in order to separate them from the network.

Hmm all cars are RHD there, always good to learn something new :)
Now I know Cyprus is not the only place in the Mediterranean Sea committed to the LH traffic :)

Ah I see. The only basic experience I have had is with an old lotus .. obviously nothing has connectors, everything has loose wires lol

I have a feeling that it might be from the glove box light as on a few occasions the light stayed on inside the glovebox, although it was shut and after tapping the top of the glove box the light went off..

I'll try and look into it over the weekend.
