Resin vehicle body grounding structure
In a resin vehicle body grounding structure, a positive terminal of a battery is connected to positive terminals of a first load and a second load, a negative terminal of the battery is connected to a first grounding structure element, a negative terminal of the first load is connected to the first grounding structure element, a positive terminal of an alternator is connected to the positive terminal of the second load, the negative terminal − thereof is connected to a second grounding structure element, and the negative terminal of the second load is connected to the second grounding structure element.
1. A resin vehicle body grounding structure to reduce ground fluctuations, comprising:
a resin vehicle body;
at least one first grounding structure element and at least one second grounding structure element provided on the resin vehicle body;
a battery and a first load; and
an alternator and a second load,
wherein a positive terminal of the battery is connected to a positive terminal of the first load and a positive terminal of the second load,
a negative terminal of the battery is connected to the first grounding structure element, a negative terminal of the first load is connected to the first grounding structure element, a positive terminal of the alternator is connected to the positive terminal of the second load and a negative terminal of the alternator is connected to the second grounding structure element, a negative terminal of the second load is connected to the second grounding structure element, and the first grounding structure element and the second grounding structure element are connected to each other, such that:
a first electric pathway is defined to be from the positive terminal of the battery, to the first load, to the first grounding structure element, and then to the negative terminal of the battery,
a second electric pathway is defined to be from the positive terminal of the alternator, to the second load, to the second grounding structure element, and then to the negative terminal of the alternator, and
the first electric pathway and the second electric pathway do not overlap.
2. The resin vehicle body grounding structure according to claim 1 , wherein the battery and the alternator are interchanged.
3. The resin vehicle body grounding structure according to claim 1 , wherein
a connection pathway is defined from the positive terminal of the battery to the positive terminal of the second load, and
the positive terminal of the first load is connected to the connection pathway between where the battery and the second load are connected to the connection pathway, and the positive terminal of the alternator is connected to the connection pathway between where the first load and the second load are connected to the connection pathway.
4. The resin vehicle body grounding structure according to claim 1 , wherein a voltage occurring at the alternator is higher than a voltage occurring at the battery so that a current flowing from the alternator to the second load and then to the second grounding structure element does not flow into the first grounding structure element.
