Fusible Link?

[CorSVXette]

A friend of mine who owned a Subaru suggested that I cary around an extra "fusible link" because his blew one night on a dark winding road and had no lights. Said it was very scary driving home. My question is what does it look like and where is it?

[ensteele]

The fusible link is found in the fuse box in the engine compartment. It looks like an upside down U and there is a fastener on each end.

I don't carry an extra one, but maybe I should. :o

The fuseable link is fount in the fuse box in the engine compartment. It looks like an upside down U and there is a fastener on each end.

Agreed, its never something i put real thought into keeping for just an emergancy but now that i think about it Its kinda silly that i don't have an extra one just in case.

[CorSVXette]

I hope I didn't put the jinx:domo:on you guys:eek:. I guess I can get it any auto store or subaruparts. com?

[Crazy_pilot]

There are probably generic ones available in certain amperage ratings. Our is 100A? Don't quote me on that.

The SVX circuitry is arranged so that the headlights and associated relays are not within the circuit protected by the fusible link. The lighting circuits comprise separate individually fused circuits for safety reasons. There is therefore no reason for concern in this regard. :)

So what would happen if the fusible link would blow?

[Trevor]

So what would happen if the fusible link would blow?

The alternator will not charge, as the charging circuit will be interrupted. Various items not controlled via the ignition switch, will not operate.

[94SubieSVX]

Suppose it does blow, would the CEL or POWER lights come on?

The charge light should come on. Diagnosing from the wiring diagram is time consuming, pulling the link will take minutes and will disclose all.

More SVX knowledge jammed into the majority of my brain:D

This just came up again because someone needed one and wanted to get one. They did not have one at the auto parts store. It is a 1.5 amp fusible link and looks like it is only available at Subaru. If anyone has gotten one anywhere else, let me know and I will let them know. Thanks :)

1.5a??? Did you mean 150a??

I think this quoted figure involves the cross section of the fuse element/wire, rather than a current rating.

[ensteele]

Maybe, but look at this and it may help. This is the cover to the fuses (http://www.subaru-svx.net/photos/files/How-To/38556.pdf). It has the 1.5 and I am not sure what that refers to. I looked in the owners manual and it just says 1.5 and doesn't give amps or anything else. :confused: All of the rest have 10A or 15A, but for the fusible link, it just has the 1.5 and is not labeled.

Exactly why I consider it refers to the cross section of the element/wire and is not a current rating.

[ensteele]

So are fusible links rated that way? You ask for one that is that size?

[Trevor]

So are fuseable links rated that way? You ask for one that is that size?

I have never purchased one and can only presume so on the following basis.

A copper wire of 1.5 m.m. diameter should have a nominal fuse rating of say 65 amps, which would make sense in respect of the SVX circuitry.

There must be someone here with spare parts experience, who can provide qualified advice.

Since I went to Autozone or Kragen...one of the two, and found a roll of the fusible link wire, and you cut to size. I've done that while I'm working on the SVX electrical issue, and when I'm finally done, I'll get an OEM one from work.

Easier and cheaper than blowing them time and time again.

How can one thickness of wire be sold as suitable for any and all possible required current ratings? :confused: The object of this thread is to define the exact specification applicable in respect if the SVX.;)

[ensteele]

I guess the only way to really know that you get the right one is to buy OEM. :)

[LetItSnow]

The rating, as far as I can tell, is either diameter or square mm in a cross section... The searching I've done has vaguely hinted at both. :( It's absolutely definitely not 1.5A, though!

I am sure that it is not as well. :o

There were several packages, all color coded and had the ratings right on the package. If I remember, tomorrow I'll go back and get the information off of them, as I've already tossed the packaging this stuff came in...

...and post up the company, and all the information.

Thanks, the information will add to the overall picture. Can you indicate the size which was closest to the OEM link? If so this will disclose the actual rating which is what we are trying to establish. :)

[Roo]

and I was a bit mistaken. There are colors for different gauges of wire, but what they offer is fusible link wire in different gauges rather than the exact rating. I purchased the 18 ga. wiring as it looked like the closest to stock for my application.

I might be wrong, but I figured rather than the 16 ga. or higher, that this would blow early rather than late.

The company that makes this is Dorman Products (www.dormanproducts.com).

search under "fusible link" and you'll find the wire in the last page.

Thanks again and very helpful information.

I had estimated from published chart figures covering standard copper wire, that 15 AWG would be the nearest, but as I understand it this is not readily available. You were right to be conservative. The supplier must be using plain wire rather than a soft wire, which is understandable.

This information should be recorded within the how too stuff as it has been hard to come by.;)

Here is what I have so far.

A substitute for the OEM fusible link:

fusible link wire in 18 gage

If any of this info needs to be corrected or added to it, please let me know. When it is ok, I will add it to the How-To Documents.

I would suggest -----

A substitute for the OEM Fusible link, OEM part number, 82301PA000 :

Suitable 18 AWG (American Wire Gauge) wire for making up a replacement fusible link for the SVX can be purchased in special small lots from:-

Dorman Products. http://www.dormanproducts.com

Plain, enameled or tinned copper wire can be used. The cross section/diameter for the original fuse link is specified as 1.5 m.m. There will be alternative wire gauges close to this which will also prove suitable. Better to choose on the small side, for a slightly lower current rating thus providing a safety factor.

[ensteele]

Thanks Trevor. :)

[ensteele]

For everyone's information, I just looked up the part number and price of the fusible link.

Fusible Link - 82301PA000 - $4.53 ea.

[Trevor]

Thanks Trevor. :)

Please note my edit where "Enamel", and now thanks to you the part number, have been added.
