Lancia Motor Club

Evening everyone.

Just been tinkering with my Lancia Fulvia MK2 1.6 HF earlier today and noticed the last fuse (far right) had blown, have tried several other fuses from 5 to 25 amp but they all blow when flicking the light switch. Does anyone have an idea what this one is for and indeed the others also has I don't have the fuse box cover and the manual is a little sketching to say the least. Also the blown fuse was black, what amp is this ?

Please see attached picture, you may notice several different coloured fuses so an idea of what amp fuse other people are using for each slot would be very helpful.

On another note are there any Fulvia owners in the West Yorkshire area ?

Cheers
Stephen

From memory Eight 16A fuses green usually fitted except 1x 30A (?) black, in position 8 counting from right to left in the fuse box there are some others held in line fuse holders too. Have you got a loose connection on light switch stalk, check the knurled ring is tight.

Neil,
I think the 16amp fuses is white, the handbook says 16a in all positions?

The picture shows a fusebox and contacts that would definitely benefit from a systematic cleaning session. Check the connectors at the back of the fuses because they might give bad contacts and shorts. The fuses are all 16A, Andrea

Definitely clean all contacts in the fuse box per fuse, I recently helped a HF owner rescue his car and one fuse with some corrosion made it run badly then not all, all my fuses are 16A, I have added extra relays and separate feeds and earths on the headlamps which makes some improvement.

Chugga who used to post here recommended putting a layer of solder onto all the fuse clips once clean to prevent them deteriorating again.

How odd! A look at the fusebox on the Safari Stratos at Castle Combe a few weeks ago revealed that it's fusebox (same as a Fiat X19 1500) had a lot of silver solder on the contacts, some linking fuses together on the battery side.

Evening,
Just like to thank everyone for the great advise and will be changing all the fuses this weekend to brand new 16a ones, have some which are red.

Will also be giving the fuse box a very good clean, any suggestions on a product I could use ?

Seems to be many different colour versions for each of the amp ratings, very strange. Nearly as strange has the multitude of differing amp and colours in my fuse box at the moment.

On another note I found a picture last night of the fuse box top with each fuses description, put it into a translator and made even less sense  :)..

Hi Stephen,
According to my handbook it has 8 x 16A fuses and 1 x 30A. As previously stated, 16A fuses are normally Pink ( originally Yellow) but they can be Red or Green.  8A are white,Black or Blue. 30A are Red or Green normally. 25A are Blue or Grey. All very confusing so read the number on the body of the fuse.
Looking at your photo I`m assuming the blown fuse is number 1. Confirm by looking at the cable colours, White each side of the fuse. If so that feeds the side lights and maybe you have a short somewhere on the lighting circuit.
I think fuse number 9 has the 30A fuse as it feeds the Heated Rear Window and horn solenoid. Cigar lighter comes off of that also but has an inline fuse of its own.
If you want to know what the rest are I will post again tomorrow.

Hi John,
Thank you for the great advise, and like you say its very confusing.
The fuse that keeps blowing is the far right one that's missing in the picture, (counting left to right number 9 on my rhd car) the rest are fine and going on what you have said it might be because it supplies the Heated rear window which isn't on my car as its Perspex. When I first noticed it had blow the fuse in there was black.

Would be great if you could let me know what the rest are tomorrow.

Thank you

Stephen

I have Beta Coupe rather than a Fulvia, but I'm in West Yorkshire (Bingley).

If your heated rear window has been removed there may be a bare wire that used to feed it going to earth. That will blow the fuse.

Neil

Interesting to read comments about the heated rear windscreen fuse.  My car (1973 Series 2 Coupe) does not have a heated rear screen but I know the screen was replaced by a former owner.  Can anybody tell me to which models the heated screen was fitted?  Was it fitted at all to the Series 2 - either as standard, or an option?  Or was it something brought in on Series 3?  Also, whereabouts did the wiring feed from the car to the screen?  I'd like to know because my electrics need some sorting out and I'd like to check whether I have a wire hanging loose somewhere that previously fed to the rear screen. 

I thought all S2 coupes and on had heater screens as standard.

My S2 never had a heated screen unless it had a replacement some time before I bought it. Although mine isn't a 1600HF so maybe it wasn't an option? A sticker with all the fuses marked in Italian and English can be had from Omicron (and probably a cover). I think so anyway - it's so long since I looked at mine, but I think I have both languages.

Hi Norm,
There are a lot more knowledgeable Fulvia owners than I, but according to the wiring diagrams and info that I have, the Heated rear screen was an option and is shown on the diagrams.
I cannot verify this physically but in my experience the wiring for the screen will go to the rear with the main loom ( left hand sill?). The switch is fed from fuse No.9 with a Brown wire, and from the switch a Red wire to a 4 way junction box and then to the screen. Fuse 9 is only live when the ignition is turned on and supplies a 6 way junction box ( instruments etc), ignition coil positive, pin 2 Horn relay and Pin 2 Radiator Fan relay.Also a Red wire feeds the oil Temp gauge from the rear screen switch.
Again, this only from wiring diagrams and may not be correct.
John.

Hi Stephen, I have recently been through the fusebox of my own S2 1600HF and checked what is connected to each fuse.  [Fuse 1 is on the right and Fuse 9 is on the left]:

Fuse 1: Right-hand Front Sidelight; Left-hand Rear Sidelight; Left-hand Number plate Lamp; Reversing Lamps; Under-bonnet/hood lamp
Fuse 2: Left-hand Front Sidelight; Right-hand Rear Sidelight; Right-hand Number plate Lamp; Lights warning lamp; Instrument Panel Illumination lamps; Fusebox lamp; Boot/Trunk lamp
Fuse 3: Right-hand Dipped Beam (outer headlights)
Fuse 4: Left-hand Dipped Beam (outer headlights)
Fuse 5: Right-hand High Beam (outer headlights)
Fuse 6: Left-hand High Beam (outer headlights); High Beam Warning lamp
Fuse 7: Horn; Fog Lights (inner headlights); Radio; Interior Courtesy Light; Door-edge Courtesy Lights; High Beam Headlight Flasher; Clock (absent on 1600HF)
Fuse 8: Brake lights; 2-speed Heater Fan; Windscreen Wiper motor; Windscreen Washer motor
Fuse 9: Coil; instrument-panel warning lights (ignition, handbrake/brake fluid & turn); Turn Indicators; Horn relay (low current); Fog Light relay (low current); Fog Light warning lamp; Cigar Lighter

All should be 16A, except fuse 7 which may be increased to 30A (your choice) depending on how many additional lights and accessories you have on this circuit.  Fuse 7 should be fed by a 6mm2 (thick) live wire if the wiring has not been modified.  Fuse 9 is ignition-controlled.  Note also that the bottom terminal of each fuse should be the live side, except for fuse 9 where it is the top terminal (at least on my car). A lot of this is described in a downloadable document that I have deposited on the Lancisti website.  Sounds like you have a short somewhere in the sidelights, number-plate lights, under-bonnet or boot lights

Hope that helps,

Glyn

Good job Glynn
 I agree it sounds like a lighting short as Stephen said the fuse blew when he flicked the light switch. Also according to his photo there appear to be white wires below the missing fuse which would signify Fuse No.1.on the right of picture. You didn`t mention the Heated rear window or Coolant Fan which are also supplied by Fuse No.9 on the wiring diagrams I have. Maybe different cars vary.
John

The coolant fan on a S2 cars is located between the starter motor live battery lead and the fan itself, or do you mean in the car heater fan/blower which is permanently live, no ignition key required?

Evening Chaps,
Fantastic information Glyn, that really does make it more clear and having another look at the fuse box tonight confirms yours and John's assessment on the fuse number (Number 1) that is. Will be hunting the lighting short down this weekend in the daylight and also giving the whole fuse box a well needed clean.

And thank you Neil, great to know another Lancia owner in West Yorkshire  ;D shame we don't have a club nearby.

Thanks John.  The engine fan does not go through the fusebox, but is protected by an in-line fuse, close to the fan.  I forgot to look at the heated rear window when I removed the fuses, but the wiring diagram suggests that it should be connected via fuse 9.

There are a few minor items that are not wired according to the handbook 1600 wiring diagram.  One is the radio, which on my car is connected to fuse 7 and not fuse 8 - mine originally had an electric aerial which may have drawn more current than fuse 8 could safely supply and was probably installed after the car left the factory.  The other is the under-dash plug-in socket which connects directly to the battery via an in-line fuse, not to fuse 7.  Finally there is no glove compartment light, or indication that there ever was!

I am sure different cars will vary in some details, but this will probably affect those items installed at the dealers or after sale,.

Hi Neil, Glyn,
Agreed the radiator fan is supplied with battery voltage from the starter motor via an in line fuse, but it would not work without the relay which is supplied with Ignition feed via Fuse 9 to pins 2 of the Horn and Fan  relays and earths the fan motor when the radiator switch closes and latches the relay contacts between pins 1 & 2 .
John

Absolutely, and it looks like it is considered good practice to put the high-current and low-current sides of the relay on separate fuses, and make the low-current side ignition-controlled.
Another feature that caught my eye was the arrangement of the lighting fuses.  Losing a single fuse always leaves a light on each side and at the front and rear.

Forward thinking,at a time when British cars were lucky to have more than 4 fuses in total!

Enjoyed your input Glyn.

John
