Battery Voltmeter Installation Question
I had problems with my 12 volt system on my FW and when I pulled the battery I found that it was only putting out 7 volts. The rig stays plugged in all the time. A few weeks ago someone posted a t...

I think you will find the voltmeter will say the same as the voltage monitor lights and not be helpful. As someone mentioned, when plugged into shore power the lights and voltmeter see the charging voltage. Even after unplugging, the surface charge in the battery will be at the charging voltage, only gradually decreasing to give a decent indication of state of charge 8 hours or more after all charging is stopped.
When you are tired of unplugging for 8 hours to measure the voltage, you will have to buy a battery monitor that keeps track of the charge (amp-hours) going into and out of the batteries. Only that provides an accurate per cent of full charge. I have a $30 one from China via eBay that works well for me.
