Hi, sorry if this is in the wrong place but the selection for the octavia forum was greyed out.

Anyway, as the title suggests, ive a skoda octavia 1.9 tdi 55 plate (mk1?). 

The fuse link for the alternator (in the little fuse box above the battery) has corroded away. The fuse link next to it has started to corrode too (and theres a hair line crack on one surface) so they both need replacing.

Trouble is, everywhere ive looked seem to give different ratings for this (these) fuses.

Ive no idea what to search for in looking for a replacement, i cant even figure out exactly what these things are called.

The ratings on these fuses are completely illegible, if they were even present in the first place. Ive managed to discern a lighting bolt superimposed over a "0", but thats it for any of them.

Itd be fantastic if someone could tell me:

- exactly what these are called

- what ratings they are

- if all these fuse boxes that look the same carry the same fuse ratings (for various vag engines), or at least all the octavia ones that look the same (iirc, they uprated the box at some point), for the purposes of pricing up complete ones (like as sold on ebay).

- if i really need to swap out the black alt cable, what should i replace it with (i remember reading these were underrated/low quality from the factoy)? What length and guage should i seek?

 

There are three of these link fuses, the alt one has finally corroded through, but the other two have different thicknesses (so obviously different ratings).

 

Theres no signs of melting or heat damage in the fuse box that i can tell, other than a slight brown residue on the oxides of the corroded through fuse (which i presume is probably oils from the plastic leeching and burning due to the extra heat from the fuse resistance/arcing).

 

Im a bit skint and limited (now) travel wise, so appropriate answers please ( )

 

Please let me know if theres any more info you need.

Thank you

Clarification

Hello Hrafnblod, and welcome.

First thing to confirm is whether your car is indeed a Mk1, or a Mk2, as there was a substantial overlap.  If the VIN number on the windscreen has 1U roughly in the middle of it, it's a Mk1, if it says 1Z instead it's a mk2. Armed with that info I can consult the relevant wiring diagram and see what I can find. 

The fuses are known as 'strip fuses' I believe.

@Hrafnblod You can't post in the "Skoda Octavia" forum itself. It is split into a further 5 sub-fora with names such as "Skoda Octavia Mk1", and you can post in those. As a further identifier as to Mk1 or Mk2, are the side repeater lamps in the front wings (Mk1) or the door mirrors (Mk2)?

Thanks for the replies guys and sorry for the tardy response, been caught up with other stuff. 

Side repeaters are in the wings, i think im fairly certain now (thanks kenoneill) its a mk1 (after a fair bit of confusing myself).

Would an autoshop/halfrauds carry the requisite strip fuses (thanks wino)?

Maybe, but possibly not an exact fit. If we can clarify exactly which ones you need I can suggest part numbers which may allow them to be cross-referenced better.

 

When you say there are three fuses, do you mean only three fitted in the 5 possible locations, or are there just three locations and they are all filled?

The wiring diagram for Mk1 Octy from October 2004 suggest that you'll have 5 locations for strip fuses, as far as I can see.

 

Is it like the photo here?: https://www.ebay.ie/itm/2008-1U1-MK1-HATCH-SKODA-OCTAVIA-1-9-TDI-AXR-SMALL-BATTERY-FUSE-BOX-FUSEBOX/332192144820?hash=item4d5831ddb4:g:dM0AAOSwWWxY-~w

If so, is it those same three positions that have fuses fitted?

corrections to numbers of fuses.

Here's a snapshot of some part numbers if it is those three. Searching the part numbers on google/ebay etc. may work better if you delete the spaces between the N and the numbers.

 

 

Thanks again.

Thats it in that picture link, and yes, its the same three.

Re, from a shop, If i can get approx sizes, so long as the values are right, i can shape them to fit (so long as i dont make them any thinner than the thinnest part).

Ill check that out thanks. Someones kindly offered to make me up a replacement cable for not very much so im about to whip that possibly degraded one out.

 

Be wary of applying stretching forces to any similar fuses you may have to 'bodge' into position, these things can fail by cracking across the thinner area, as well as burning out electrically. They're not very mechanically robust. 

 

50A, 110A, 150A  in positions 2, 4 and 5 respectively, for your car.

I was thinking more along the lines of removing material from a slightly larger one (physical size) to get it to fit, but thank you for the heads up.

Thank you very much, youve saved a huge headache (hopefully, that being the whole of the problem).

Take care

Forgot something

Thanks everyone. After phoning and visiting around many numerous places that *should have had them, halfrauds were the only ones (although, on the phone, he couldnt find anything like them in their inventory. He told me they dont sell those. However, after id pointed out i can see them on their website, (i even gave him their item number), and he still couldnt find them (or work thier search engine/database), he went and asked their mechanics, who had neither a clue as to what i was asking for.

Anyway, once id convinced the guy they definitely do sell exactly what i needed, he tried entering the code "somewhere else", and found they indeed had 5 in stock.

 

For anyone else that needs these hens teeth, they are available from halfrauds if all other avenues fail.

 

Item code 333310 (their internal item code)
"Assorted OTO strip fuses" code (as displayed on the package) HFS299" which are VAG compliant and pure zinc, according to the package.

80, 110, 150 and 175 A.

£3.70

 

There is another pack, HFS298, which have a lower current rated range of strip fuses (up to 60A i think), which, iirc, where slightly more expensive.

Fortunately, the 50A fuse (60A stamped upon the respective one in my car), in my car was fully intact, so i didnt need that pack too.

 

Ive not put a multimeter on the job, but already after a bit of driving about the battery seems less "tired" the next day. After chrimbo, replacing the alt-batt cable and hopefully the alt and its loom will last the life of the car now (lots of susp. work i suspect will be required for mot time mid jan.......)
