For a long time I've wanted to remove the Amp meter from the circuit on my 'Cuda but the thought of hanging a voltmeter under the dash and having a dead gage in my instrument cluster did not appeal to me. Following is my mods to the instrument cluster to remove the amp meter from the line and replace it with a fully functional Voltmeter. Located in the archives are the instructions for taking the amp meter out of the line and making a good connection so I will not rehash those instructions. First I needed a voltmeter that had the needle on top like the amp meter and read the voltage under neath. Summit has a Sunpro Mter ACP7985 that did this.
