Install the battery by connecting the positive cable first,then the negative.If this does not work,do it vise-versa.connect the negative first,then the positive cable.If this does not work,connect the battery,and then insert the key and start the engine,if horn stops,let it run for about a minute,then turn the ignition off and remove the key.

I'm trying to put in a new battery in my 94 acura legend but the horn goes off non stop what should i do to fix it so i can start the car

Sounds like a anti theft. Put your key in the ignition but not in the start. just put it in. See if you can remove the battery now without the horn going off. If you can also find the horn and un hook it. there should be a connection clip if you trace the wire down.

Hope that helps

The alarm won't go off

Try this:
SAVE radio code and remove the negative battery cable,turn on the headlight switch for 30 seconds,turn back off,start truck.
That MAY re set the alarm relay.

My horn does not work what to do to fix it

There are a few things that can cause the horn to stop working. First thing to check is to use a 12volt probe light and take the wire off the horn, put the probe between batery ground and the horn wire now have somone push the horn switch, if the probe lights then change the horn. If no light then chech the horn fuse. If the fuse is good then maybe the switch. Pop off the center of the stearing wheel and mak sure the switch is clean and shinny if so you are now looking for a broken or disconected wire. Good Luck

First of all I would go to like Checkers, or Auto zone and let them put a battery draw down tester on your battery and check the battery.Second I would check your battery connections if the batter checks out. Also check engine grounds. You will hear noises when re-powering up. That is normal.

No power from batery to anyplace

Check the voltage drop on the battery cables, they may be defective.

Security system/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.)
