Re: Adjusting 32's horns

THis statement:
" I'm using an adjustable 3A power supply. The good horn draws 1.5A. The bad horn is maxing out the 3A current from the supply."

explains this qusetion:

"I'm am puzzled though why one draws only 1.5A and the other one is in excess of 3A."

That's because your power supply is ONLY rated at 3 amps.

As Owen has indicated, a horn requires alot of power which means a lot of AMPS!! Much more than just 3 amps. So any maximum power that the 3 amp power supply could ever produce just simply passed thru the horn circuit with little or no effect. Just not enuf amperage available.
