Hello Everyone,

Going thru a bunch of stuff I've been putting off and one of them is getting my town and country horns working properly. Would anyone out there have a line on a company that works on these beauties ??

The long one makes noise but not sharp and the short one is very weak. I have the instructions to adjust them and I have tried a couple of times but I believe they need an experts touch.

I am not aware of a particular service that works on these horns. I expect that someone who repairs the electrical equipment or radios on these cars should be able to do it. A horn is essentially a vibrating coil.

I was able to get mine working very well with a few steps before adjusting them. I carefully sprayed the coil area with electrical contact cleaner and wiped away any dirt, cobwebs, etc. I let that dry well. I then used strip of 400 sandpaper folder over to pull through the contacts just twice. All I was trying to do was remove any oxidation. I then blew them off with compressed air. I also checked the resistance of each coil to make sure that current would pass through them and that they were not shorted.

The adjustment is simply setting the gap on the contacts. If the gap is too large the points will not close again quickly enough to start them cycling. If it is too small the points will stay closed and just overheat the coil. You can watch the gap change as you move the adjusting screw. Try that before you connect them to power.

I set each horn individually. Use 12 gauge wire to connect them directly to the proper terminals on the battery. They draw a lot of current so you need the bigger wire. If you are trying to run them with a battery charger or small 6 volt power source they will not work.

There is a guy who works on the Horns. He has done several for me. His business is "The Horn Shop". I've also repaired my own. Sometimes the horns are burnt out and cannot be repaired.
