Changing Sienna 2000 battery

Car wouldn't start after a winter if sitting in the driveway.  My son bought and try to replace the battery.  He can't seem to connect the last terminal (negative) without the horn blaring continuously. Any suggestions on how to finish installing the new battery.  Thanks.

The horn relay is stuck. The fuse box is right by the battery, remove the horn relay (it pulls straight out) and replace. The guide is in the lid. Removing the relay (or the 10A fuse, tool is also in the box) will stop the horn, but the relay's contacts are probably locked.

Sometimes just a little shock will dislodge the contacts that are locked together, but it's probably worth replacing with new.

have the battery load tested as there is no guaranteed service life for batteries ( that is why you get a warranty period )
next have the charging system checked by an accredited auto electrician ( alternator , voltage regulator and drive belt tension and possible current leakage from failed relay or wiring problems )

MR 2000 toyota would not start after sitting all winter.

the battery can be disconnected if you let it sit for more than a week. most common drain that i encounter is in the audio system. disconnect the negative battery cable and put a test light (wired light bulb) between battery post and cable end. if the light is on or even dim, start pulling fuses one at a time. if the light stays on, replace the fuse and move on. if the light goes out then you have found which circuit the draw is in.

When your battery light comes on it is telling you that your ALTERNATOR is not charging your battery! So you need to replace the alternator.

You can verify that it is bad by taking the car or just the alternator to an auto parts store and having them test it for you for free.

Corolla has been sitting on driveway for year and a half now without being started. What kind of maintenance can I do to get car up and running?

Oil change with oil filter replaced, air filter change, gas would be an issue to you might have water running in the fuel lines when u try to start it, drop some fuel injector cleaner in your gas tank and bring some fresh gas as well. charge the battery well and give it a run. Then check your brake discs or drums for any rust that builds up especially if you live in a winter state with snow coming through.

Good luck.
