Hi Jeff,
In an automobile, which is isolated by the rubber of the tires, it makes no difference which terminal of the power source is called "ground". Electrolytic corrosion is not an issue in an isolated system. Just as an unrelated side note, I do recall many years ago seeing braided metal straps hanging from automobile rear axels to make ground contact. I have no idea why, nor if they were effective (I have my doubts about both the longevity of the ground straps, and the strength of the ground connection, thoungh maybe for discharging static buildup ...?). In point of fact, it doesn't matter at what level you define as zero volts, circuit common, whether you pin any point along the circuit to earth ground or not. The voltage drops just have to sum to zero. Likewise, whether dealing with electron flow or electrolysis, if the relative potential is present it doesn't matter whether the system is earth grounded or not. |
