So I replaced the dual horns(don't know if they're stock) with a hi and lo fiamm. I turn the key and the and the horns start blaring. I check the wires with a meter. One is hot all the time regardless of wether I hit the button. The other has nothing. When I take a reading between the two it read 3.4-4volts and then 12 when I hit the button. What's the deal? The horns are loud as hell. Totally confused. Thanks in advance!
