The 12Volt Guy. The largest off roading and 4x4 website in the world. So long as the battery continues to produce voltage and the continuity of the electrical path isn't broken, electrons will continue to flow in the circuit. This continuous flow of electrons through the circuit in a single, unchanging direction is called Direct Current, or DC. Conventional vs. Electron Flow "Wait just a second! " This is the difference between what's known as "electron flow" notation and "conventional flow" notation.
The apparent discrepancy began many years ago with Ben Franklin. By the time the mistake was discovered, the idea of current flowing from positive to negative was so well entrenched (as indeed it is with most of us, me included!) Unfortunately, Ben was wrong, and had the flow backwards, so that using his now unchangeable labelling, electrons ACTUALLY flow from the negative terminal to the positive terminal. This is known as "electron flow notation" as it is the actual atomic truth of the direction in which electrons flow. Resistance. The largest off roading and 4x4 website in the world. The functions of the terminals are as follows: Notes: - Alternator will have either an “F” terminal or an “I” terminal, but not both. If the alternator has an “F” terminal (i.e. no "I" terminal): It must be excited by the L terminal.
When exciting via the L terminal, there must be some resistance in the circuit (bulb and/or resistor) or a short circuit will be created. If no alternator warning lamp is desired, a 50 Ohm resistor is used. Wiring It should now be obvious how to wire a CS-series / 4-terminal alternator, but just to summarize: PLFS-type Mandatory connections: 1) Connect the alternator output terminal (B or Bat) to the electrical system's main distribution point (bus bar, junction, etc.) 2) Connect the L terminal to a source of switched ignition power through an indicator lamp wired in series.
Crucial connections: Optional connections: 5) If you have an external device such as a tachometer, hourmeter, or other device, it may be connected to terminal P. PLIS-type Plugs or Max Speed.
