Sounds like (no pun) it is the alarm system going off. After installing the battery try using the key fob to deactivate the system.

SOURCE: 2003 - RX300 I'm tring

I would check to see if this is a relay problem for the horn. Remove the relay for the horn and see if you can swap it with another to confirm it is bad. If with another relay it doesn't stay on you no it was just a relay so go get a new one. The only other thing could be a security issue and when you discharged the power by unhooking battery the vehicle is acting like it has been broken into. But i would say it's a relay problem. Good Luck.

Check wiring for any melting, cuts or damage. This kind of problem occurs when some part of the loom has been damaged, exposing some open wiring crossing circuits.

Horn blows after I installed battery


Attach the battery cables to the correct positive and negative connections,close the hood,use your remote to lock and unlock the doors and the horn should stop.The vehicle may be in anti theft mode and locking and unlocking the doors with them closed should put the vehicle back into normal mode.
Your radio may show antitheft mode now and the code to return it to normal should be in your vehicle handbook in the glove compartment or attached on a sticker to the side of the glove compartment.It can also be had from a Honda dealer.DO NOT EVER REVERSE YOUR BATTERY CABLE CONNECTIONS.

damaged wire maybe.
Locate the horn that blows and follow the wire back until you see the damaged area.

Should only be one power wire running to the horn.
Very strange that the fuse/relay didn't stop it from happening.

let me know what you find.

The fuse for the horn keeps blowing. Any reason


Most common problem is the ground that the horn connects to wit the bolt is rusted and causes it to pull to much amperage so clean the contact first then if it still blows the fuse then the horn relay or the horn may be going bad.over time the horn gets junk in it and causes the coil to overheat and causes it to burn out. Horns cost $15.00 for a new horn and are easy to change. I doubt the relay is bad but it is always possible.
