I''m about to install a voltage sensitive relay which will be in between my car battery and my auxiliary battery in my van. When doing research for this, I find diagrams like this: What confuses me here, is ground, and if I should be grounding my aux battery to the chassis, and what would be the purpose of this?

batteries

In a battery, a chemical reaction takes place which makes the electrons leave the positive terminal, leaving ions, and gather on the negative terminal. This makes a potential difference across the terminals. When sufficient voltage difference builds up between the electrodes, electrons can no longer make the journey across the battery and the

How Does a Positive Ground System Work?

A positive ground system works by directly connecting the chassis of a vehicle to the positive side of the vehicle''s battery. This system effectively earths the vehicle as the

Should Negative on Battery Bank Be tied to Ground?

The battery is galvanically isolated from the inverter and PV input, therefore the battery positive or negative terminal may be grounded if required. Very clear (not all manuals are written with clear grounding instructions).

Why does a bulb not glow when one terminal of a bulb is

Returning electrons to the battery prevents the battery from acquiring a positive charge due to losing electrons. This is also why a person with wet hands is not shocked when touching a single terminal on a battery (and why the unpleasant way of testing a 9-volt battery requires licking both terminals).

Is ground positive or negative charge?

Direct current circuits that have the negative pole of the power supply connected to the ground source are negatively grounded electrical systems. Typically the positive pole connects to one

What are the tradeoffs for positive vs. negative ground?

Originally, the voltages on the wires were positive with respect to earth. This is called negative ground, since the negative side of the battery is grounded to earth. Then engineers discovered that with positive voltage on the copper wires, copper wires age quickly, due to electrolysis.

Why do we connect a battery to ground when jumping a car?

The circuitry in the car is also grounded to the chassis, albeit with some other protection in between, but this has nothing to do with the current flowing from one car to another during a "jump." If anything, this circuitry can be destroyed from spikes in the battery voltage. $endgroup$ – Kurt E. Clothier. Commented Jul 5, 2013 at 7:42 $begingroup$ When you
