I've got a question for you electrical guys. A friend gave me some old horns from a '57 Chevy truck, I'm looking at them and there is a single electrical blade connection for positive and then the grounding is by means of bolting to frame etc. I want to replace the stock Harley horn with one of these. It should be loader than the stock.
Will there be a difference in electrical draw or anything I need to worry about? I think they are from a 12 volt system. This will go on my '96 Road King.


Thanks.

 

12 volts is 12 volts..... stick em on........

 

If there's a significant amp draw, you'll need a relay to power the horn. The buttons load capability is limited.

 

TRUE! I had to use a relay when I installed my air horn.........

 

Wouldn't hurt to throw an ohm meter on it and compare to the stocker.

 

Thanks for the replies. I had not thought of an ohm tester. I am going to try and get to this this weekend and see what it does. Just did not want to fry anything.

 

If you want loud, spend the $40. and get an air horn.

 

That could be an option later on. Just having a little fun now with stuff on hand. I also have an old Mercedes horn from a mid '70's SL 450 I was thinking of trying before I got these Chevy horns. I can only hook up one of the old Chevy's as they're kind of big.

 

Then test 'em. Most horns that come in pairs have a high and a low. You don't want to sound like a stuck pig do you?
