The battery symbol appears to be made of layers or plates, common to internal battery construction. The resistor symbol appears to impede energy flow, which is a resistor function. Variations of symbols will exist depending on function or other characteristics. Abbreviated codes on the diagrams provide circuit path and part or component information. The codes or labels may be used to show circuit connector pin numbers, circuit values or component polarities that will add clarity to the diagnostic drawing. Being aware of the color of a wire is important.
For consistency in reading, most electrical schematics have signal or energy flow from top to bottom, with component inputs on the left and outputs on the right. With an understanding of how a system would function, the electrical diagram is probably one of the most valuable resources a technician can use in repairing a vehicle. FOG LAMP INSTALLATION When wiring anything in your vehicle that draws heavy current such as high powered offroad lights there are a few things to consider. Number one, make sure you use wire that is rated for the amperage that the accessories is going to pull. Use wire that far exceeds the current draw of accessory. It’s overkill but in a few applications we’ve used heavy gauge stranded industrial wire with water and chemical resistant insulation.
That way there is no question as to whether the wire is rated high enough or not. If this approach is taken, it is very wise to place a fuse at the battery end as close to the battery as possible. With accessories that pull a lot of power it is always better to get your power directly from the batteries positive terminal rather than tapping into the existing fuse block or wiring harness. In almost every case where high current is required the switch use to turn on the power should not handle the load. That is better left to a relay.
A relay is a device that, through a magnetic induction coil, turns on the power for you. 4 actually only powers the relay itself which draws very little current. The method used for wiring the lights and other external accessories, for the most part, follows the diagram pictured above. As in the diagram a wire is run from a 12 volt power source to the switch in the cab and out to the relay placing a fuse at the source of the power. One of the relays terminals goes to ground. One ohm is the resistance value through which one volt will maintain a current of one ampere. Current is what flows on a wire or conductor.
Voltage is the difference in electrical potential between two points in a circuit. Resistance determines how much current will flow through a component. Resistors are used to control voltage and current levels. The higher the resistance, the smaller the amount of current is allowed to flow.
Power is the amount of current times the voltage level at a given point measured in wattage or watts.

Macam mana saya nak pasang switch dengan relay untuk pre amp? 2 kali tukar dalam tempoh setahun. Utk relay fan radiator brp Amp yg harus digunakan utk proton wira? How many type of connector in proton’s persona and how many pcs of connector in this car too ?
