DIGITAL VOLTMETER
The analogue volt gauge in my van was reading about 1.2V on the low side , showing 11.7V or thereabouts . I put a multimeter on the battery and it was resting at 12.9 .
I purchased two digital volt gauges from Jaycar , and then designed and 3D-printed a holder for both new gauges .
My van currently has just the one battery but I fitted two gauges in anticipation of getting a second battery . Now , I have an accurate voltage showing .
