ALL 15 amp fuses

Featured Replies

Hey All,

 

So I got to looking at the fuse box in my '89 DL, and noticed that some PO had replaced ALL the fuses with 15 amp fuses!!

 

:o  :banghead:

 

Is there ANY legitimate reason to do this, other than the most dire of dire emergencies, or to have one wrapped in foil like I found? 

 

Going to have to address that ASAP. 

 

John

bad ju ju...

 

never up-size a fuse...they has amp ratings for a reason...you're gonna melt something eventually...

 

fix that crap now!!!

I've never seen anyone do that!

 

All I can think is he was stranded in the middle of nowhere, or he got them on sale, or he didn't know jack about cars.

PS: hope I don't have a bunch of shorts to run down...

I don't understand the problem?

Is this car a Loyale or the older shape?

Pre 87 had a 20A fuse for the central locking & another for the rear demister

Post 87 changed to 2x 15A fuses for the rear demist

 

If your's is a DL, it won't have central locking, so its supposed to only have 15A fuses.

No....Charge fuse is always a 10Amp

 

All the others it won't matter they'll just blow easier

It's an '89 DL wagon, the style with sealed beams not composite head lights.

 

Every fuse in the fuse box is supposed to be a 15 amp fuse? Hmm. I guess I'd just never seen a car or truck where all the circuits in the harness had the same amperage fuses. But I'm learning that subaru does things differently! Lol

All the ones I've had only ever had blue fuses with the odd yellow one. Maybe we got bigger alternators here :P

 

Before this thread was started, was the fuse panel cover read? ;)

 

With the Legacy (which has a lot thinner wiring), Subaru went to a heap of different fuse ratings. But it's damn handy to have a lot of the same one, especially when you've blown 2 by accident & have no spares. Just remove one from a non essential function and hope that there's not an extra circuit hooked in that's not labelled... (like power mirrors :( )

Good point Wagonist. I did not read the fuse legend. It would in fact have practical benefits tho only need one kind of fuse. 

 

This being my first Japanese car and my first Subaru, I obviously have a lot tip learn!

 

John

check the fuse box lid or owners manual...it will tell you what each fuse should be.

 

 

all the same would be nice but I don't think I've even see a car like that.

I seriously doubt they are all supposed to be 15 amp. My '88 GL SPFI is not like that, by the book or the fuse cover. And there isn't that big of a difference, if any at all, in the way a DL carbie would be wired and therefore the fusing should be similar.

Nah......Charge lamp is always 10A.  Nothing to do with Alt max output, just the bulb on the warning light circuit, and a few Ma to excite the alt.

 

Amps are Amps in any hemisphere.

You were saying?

 

Attached pic is from a 92 model.

 

I'm guessing the charge "fuse" is in the engine bay & is one of the 3 (or 4 depending on model) fusible links

Ha!

 

Well there you go! Learn something new every day! And my DL is teaching me a lot! :-)

 

John

Yeah, I still have all the original fuses (I assume so, looking at the style of them compared to the new ones available) and there are only 3 yellow (20A) in my MY91 Loyale. Locks, Wiper/Washer and a spare. The rest are 15A.

I guess in the 80s, copper prices weren't so bad :P But it's also wasteful.

If you look at the thickness of the wires in the Loyale vs a Legacy, they are all much bigger, and hence the differing fuse ratings.

 

The only problem with the new system of wiring is you need so many different rating spare fuses, and then if use one, and then forget to replace it, you end up stuck somewhere :(
