    Resistance Wire Cut and Splice - Too Much Current Now

    Thanks for the reply. Simple automotive quick splice. Although that doesn't seem to be the issue. The resistor wire provides ~24 ohms of resistance which sounds about right... Would pull ~5amps at 110v. Which brings me back to the question of how to power this for testing. Is there a...
