    When testing continuity of wires, should the battery be disconected? or the key off?

Grab a volt-ohm meter from Ace for $15 and switch it over to test current (set it to the smallest number, like 200mA instead of 10A, so that you can catch even tiny current). Poke the ends at the wires going through the horn (or other suspected culprits). If the item is sucking juice, you will see current flowing through it. This works for this application because the components that could drain your battery while you are away are wired in parallel (so if one component goes out, the whole car doesn't go out like christmas lights and also for better electricity distribution).
This little trick will serve you well in your hobbies. Volt-ohm meters are fantastic machines. Another trick: switch it over to test resistance (ohms) to test continuity of wires, and overall quality of remaining factory wires. You'll get a good feel for what the resistance should be on various gauges, and you'll know right off the bat when you see one with an unusually high resistance. O2 sensors, various thermometers, and wiring to various gauges will often deteriorate, especially near the coasts, and cause the Check Engine light to come on, fuel mixture to be unbalanced (in a car with a CPU), and you know what happens after you spend an arm and a leg replacing those sensors, gauges and thermostats? you pay your remaining arm and leg to a mechanic to run diagnostic tests, charge you for unnecessary overhauls, and pretty much royally screw you for the replacement of an 18 gauge wire that would have cost $2 at radioshack.

I have the same car i think it was a problem with our blower/ac control, otherwise check that there is nothing plugged into the lighter socket, we have had problems with the trunk light staying on as well remove the bulb from the trunk and see if that is the cause...

Location horn relay on 82 cj7

The horn relay primary receives + full time and is actuated by receiving ground (-) from the horn button. Check ground continuity at the horn button (at the steering wheel) to make sure it is working first (most likely culprit). If the horn button is working, check to see if the horn relay is working (second most likely culprit). To test the horn relay, provide chassis or battery ground to the (-) primary terminal of the horn relay and see if the horn honks. If it does, that will tell you that the problem is in the wiring between the steering wheel and the relay, most likely a disconnected wire at the steering column.
The only other components in the system are the fuse for the horn circuit (if you have 12v at the horn relay, that is fine), and the horn itself. My bet is on the horn button pad itself.

Not being smart but get a manual or youtube it. You need to remember that the air bag is located near the horn device. You can be hurt by the bag if it inflates.

How to install car horn bypass switch?

find the connector for power on the horn. the ground is likely the connector to the body. run a wire to a button you have mounted in the dash. they sell large horn buttons in autozone. run the wire from the button to the battery. when you press the button you complete the circut from the battery to the horn and the horn will blow if the horn is good. Please check that the horn is good before doing all this work by running power directly to the horn just to check if its working.
good luck

Battery draining

Check to see if there is a broken/bare wire on your horn circuit. That would explain the battery drain and the horn not working if there is a short.

The horn of my KIA CArens has stopped working. I suspect something at the push at the steeing wheel. Any help

check horn fuse
measure voltage at horn
one wire will be earthed to car body hopefully and the other wire will get plus 12 volts when the horn is pressed.
or one wire is always 12 volts and the other wire is connected to earth when horn button pressed.
check fire wall of car some kia have horn on firewall in engine compartment. or it is under the grill in front of car.

2003 dodge caravan airbag good horn doesnt work,so i jumped horn relay horn worked .so i now know relay to horn is good clock spring wiring horn pad?fuse compartment on wiring diagram has horn relay 20 amp...

if you check the wire that comes from the horn button to the relay for voltage when the horn is pushed and have voltage then you have a bad relay,if not then you probably have bad contacts in the horn pad area or even the clock spring itself.

Horn does not work. Clicks when button is pushed.

Check the wires on the horn. Wiggle them while someone activates the horn button. Next connect a hot wire from the battery directly to the horn. If there is no change the problem is probably a bad horn.

Horn won't work. and already checked fuse.

the problem may be that the horn is faulty or the horn button on the steering wheel is not making contact, check for loose wires & connections, to check the horn remove the wire(s) from it then connect a wire to the positive terminal of the battery then to the horn if the horn is OK it should work if not it is faulty & will need replacing,if the horn has two wires to it you will need another wire from the negative terminal of the battery to the horn as well........hope this helps......cheers

Something is draining the battery on my 2000 Jeep Wrangler. We have a new battery, alternator checked okay, new starter. The jeep starts, lights come on, and then will die while driving. What could be...

Put a volt meter across the battery terminals while the vehicle is running. You should read no less than 12.5 volts at idle with no accessories running and no less than that with accessories all on. Normal volts should be around 13.5. Aside from slight fluctuations, the voltage reading should not steadily drop, regardless of how long it is running. I doubt if you have a system drain if it's shutting down while driving...the alternator would compensate for that. Some charging systems incorporate the voltage regulator into the computer. If the alternator checked good by itself but the tests I recommended show otherwise, likely your problem is with the computer.
If the engine does not need to be jump started after it shuts off, you may be looking entirely in the wrong place...but you didn't mention that part!!
