velcro/superglue/12V meter bought two from ebay. glue the velcro to the meter and another velcro has double tape.
Are you able to read the voltage with the vehicle off? When the vehicle is off, you are provided with the information that tells you the real status of your 12v battery
not during off, but you can read it when the vehicle is in POWER mode, ACCESSORIES mode and Drive mode. I can hard wire it to the battery under the seat,but it take a lot of work . I am little lazy. just plug it into the 12V plug.
