I came back from vacation my 2000 honda accord would not start battery is dead. I got a jump from someone. The car started right up but the horn continuously blows and wont shut off. Had to have car towed 200 miles to my home. Is there anything I can do to make horn stop blowing. It is a new battery in the car, so the battery shouldnt be dead in the first place

No trick to it. It should not be happening. I would disable the horns right at the horns themselves until you get the vehicle started and the battery charging up. Then you can deal with the horns. An electrical genius may have to diagnose it. New car problems are bummers.

If there is no power presently, most likely it blew the fusible link, Honda's have a fusible link just off the battery and is located usually along the inside of the passenger fender follow the wire from the battery and you will find it, most likely that is the culprit, good luck.

You could have blown the main fuse while doing the jump start. Also check the fusible link on the power battery cable.

The first thing I want to mention is that if the vehicle goes crazy like that make sure you are jumping it correctly with positive and negative in the right locations. The reason I mention is because if it is jumped incorrectly it will cause the vehicle to make the alarm go off like that and could fry your whole electrical system. Try jumping the car it may be a alarm issue, that goes off when power returns to the vehicle, use the remote to try and shut it off. If that gives you no luck, then turn next to your charging system. This would mean your alternator or starter, either one of the two could have gave out on you during that period. If that still does not work check all your fuses to see if there are any popped, and also try and get it to a autorepair shop, they would be able to determine of a sensor has affected an electrical component within the system. My best gues would be either a short or a problem with your charging system. Those two aspects would be you'r best bet.

Hope This Helps!

reset the alarm/immobiliser according to the book......(every time the battery is disconnected.)

vacuum leak.open hood and have someone start car.when motor starts to die spray carb cleaner over motor if isuddenly acellarates again then its a vacuum leak

there might be some corrosion on the plugs that hook onto your battery.

you will need a new altenator and a battery

plz check the following and update me
1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)
