2001 Toyota corolla alternator fuse keeps blowing

[Meggatron]

I recently got my drivers lisence and went to get my car ready to drive. I had thr battery trickle charging for about a 2weeks I put the battery in and as soon as both terminals connected the headlights and horn turned on and wouldn't go off so I unplugged it took the horn fuse out and reconnected the terminal. I figured it was my alarm since I unlocked the door with the key I go to turn the car on and nothing no turnovers or anything so I looked it up and found to check the am1 and am2 fuses and the am2 was blown so I put in the spare turn the key and I get alittle turn over and it stops go back to check and it blew then I notice the alternator fuse is blown so I take out the battery go pick one up replace it put the battery back in and as soon as both terminals connect I hear the fuse blow again. I'm not sure how to fix this or how to figure out if i did fix it without blowing tons of fuses any advice would be appreciated

Are you sure you haven't connected the battery the wrong way round?

[Meggatron]

Yes I am sure

Such an odd issue. AFAIK the 2001 Corolla only has an immobiliser and no alarm, regardless of it being opened remotely.

Are you sure the fuses are the correct type and amperage? If they're lower then they'll blow the moment power goes through them.

[Meggatron]

Yes it's the exact same as the one that was in before

But is it the actual fuse that's meant for it? Have you checked it against the fuse box diagram?

What is the history of the car by the way? Is it a new one you've bought or have you had it a while parked up?

I bought it used it has been sitting for a few months

What springs to mind is that you could have charged the battery the wrong way around and blew the alternator diodes when connecting it up, the diodes will often blow before the fuse blows

Now you have a correct polarity battery but there is a short on the alternator that keeps blowing the fuse

If the battery was charged the wrong way it will very likely have damaged other components

I wonder what happened

[E-bmw]

I wonder?

[Penelope Stopit]

You best wander while you wonder

[sgtBerbatov]

One wonders where to wander while be ponder what we wonder.

[Penelope Stopit]

If you ponder while you wander you will wonder how you ended up out yonder
