voltmeter question

I had installed a little voltmeter in the dash off the aux spare wires. It is not giving me the correct volts. If I put a meter across the battery there is a few volts diff between the two readings. Is it better to wire the voltmeter directly to the battery?

Best is to run a major 12 volt wire (fused near battery) from the battery switched through a relay triggerd by the aux lead then you will have a low volt drop and source for high powered switched source aux (cig lighter, lights, etc.) up front.

There are a lot of other circuits tied to the aux up front including loss through the switch, wire size etc. This will cause quite a drop in voltage compared to right off the battery. Best reading is an independent run direct to the battery.

Best solution is a fused (near battery) lead to the front (large wire) to a relay triggerd by your aux lead.
Then you have a switched aux high power source up front.

What gauge would the large wire be?

14 gauge should be sufficient for running up to 5-8 amps (on a 10 amp fuse). If you are just running a wire for the gauge alone, then something smaller would work as gauges draw very little current.
