The best is to use the BAT+ plus  AT THE AMP Metter today. so when you connect the two AMP kabels add a thin wire to it as VOLT + connection. 

 

Connect the voltmeter to a SWITCHED 12 volt source.  Otherwise, the volt meter will be a constant drain on the battery when the ignition key is turned off.
