battery change, blown fuse

Have a look in the owners manual, it will show where the fuse box is. If you haven't got a manual look under the dash or in the engine bay.

Look at the fuses and the one that doesn't look like the others (Broken fuse inside of holder) needs to be replaced.

Now be careful there is a reason the fuse blew. If the fuse is for the air conditioner or something not required to run the car leave it out. Go and see an auto sparky to fix it. If you need it to run the car NRMA, RACQ etc needs to have a look.

In a Hiace with the battery down under the floor its very easy to touch a terminal on the edge of the floor putting it in.
Also bloody hard to jump start one by the position of the battery box.

I agree it sounds like it may have been hooked up incorrectly. However diodes in the alternator will not protect anything that is powered directly from the battery with the key off. Is the key was on you may have damaged more stuff.
