In some instances you may be asked to troubleshoot your interface by connecting it to an AA battery to rule out a hardware issue, here's a short how to.

First you'll need to insert the raw voltage pid into the #1 slot in your table display 

Next you will need to connect a small 3-5" long piece of 16-20 gauge wire to the #1 port on your MPVI Pro interface

Next you will need to connect a small 3-5" long piece of 16-20 gauge wire to the #5(ground) port on your MPVI interface

Next you will need to connect the #1 piece to the positive terminal on the battery and the #5 piece to the negative terminal.



Now connect your MPVI to your vehicle and begin logging

Without the AA battery connected the voltage will likely hover around 1.34-1.37 volts this is perfectly normal.
