anyone have a part number handy for a main fuse for a '00 Legacy? or if that's the wrong terminology, help me out!
Darkness + jumper cables =
and here's what I've done since (x post from electrical forum because... well, i'm desperate)
So, friends, I screwed up. My battery died at my friend's house last night, and in my haste to get home, I reversed the jumper cables on my battery. Cranked it and got nothing but continuous horn until I disconnected. Found out that I blew the Main Fuse (the one that bolts in).
Well, it's a 100A and I could only find an 80A locally so if anything, it's less likely to do any harm and more likely just to blow. Great.
Jumped the car (the right way, this time) and it started right up and idled fine for 5+ minutes, which it rarely does after an ECU reset.
Go to drive home and I'm getting:
- an intermittent (though more on than off) ABS light.
- just a flash of a CEL with a MAJOR hesitation (like, 1/10 second of a dead engine) that does not stay on, nor does it repeatedly flash like in a misfire condition.
- fast flashy blinkers, at least in the cluster.
- battery also completely dead when I got home (~5 miles) so no restart and no diagnoses until I replace it. It might be 10 years old, as I've only been the driver since 2005.
So, mighty Nasciocers, what did I fry and how do I go about testing those things? Unfortunately, I'm broke right now too, so no expensive answers please .
Battery died. Reversed cables on jump in the dark. Fried main fuse. Now about to replace battery and chase gremlins. HELP!

just go to your local subaru dealer and get the 100a fuse and charge your battery and you should be good to go....the reason it did all that is because that fuse is for the alt....so you were running on just the battery whitch isn't enough to power the car for long without the alternator..

Most modern alternators have the voltage regulator integrated in to the alternator. It is very likely that when you mis-connected the jumper cables backwards you might have possibly damaged the voltage regulator so that your alternator might be what we would say "kaput". If your alternator is indeed "kaput" your best bet would be to either source a cheap junk yard alternator for your Subaru or to obtain a rebuilt alternator from an auto parts store. Getting a brand new alternator from a local Subaru dealership will likely cost you several hundreds of dollars more than a rebuilt unit.
