Alternator and Regulator Wiring Diagrams, TDV6 and petrol V8 and V61973 viewsThis is a three page pdf that shows the alternator and regulator wiring for the petrol V6, petrol V8 and TDV6. The pdf can be either printed or by right clicking on the displayed pdf, rotated as required for viewing.
Of interest is that the regulator gets its instructions primarily from the Engine Control Module (ECM) and only secondarily from the vehicles electrical buss. The conductor from the battery thru the 5 amp fuse F20E is to provide initial power to excite the alternator at startup and then secondarily, to instruct it if the PWM signals were not available. Primary instructions to and from the ECM are thru the two other conductors via a digital like Pulse Width Modulated (PWM) signal.
If F20E, the 5 amp engine compartment fuse box fuse is blown, the red alternator light on the dash will be illuminated. This means that the alternator could be OK, but if the F20E fuse is blown, no electricity will be generated. Hence check the F20E fuse if you get a red ALT light or some indication of the alternator not working.
Regarding operation of the red ALT light on the dash, it is not the regulator within the alternator that tells the red light to illuminate, or not, but instead the ECM. This is the reason the red light does not function in the same manner as with older vehicles. With the 3, sometimes you have illumination and sometimes not depending upon what the ECM is thinking. What this means is that you can have an alternator that is failing but the red light does not illuminate as the ECM is compensating for reduced alternator output - maybe by draining the battery and or cutting back on vehicle electrical loads such as shutting off or cycling the radio amplifier or heated seats.

Battery check display14 viewsI mounted a digital battery display in order to see the voltage on the auxiliary battery.
There's also a thermometer which gives the inner and outer (via a side switch) values.
The display is switched on/off via another rocker switch.

LP scoped 218 viewsBy connecting a Low Amps probe to the fuel pump's voltage supply wire, you can view the pump's current waveform on a digital storage oscilloscope (DSO). The scope pattern will reveal internal wear in the brushes and commutator that may not show up in a traditional pressure or volume test.
Observing the waveform will show if the pump's amp draw is normal for the application or is high or low, and if the pump is operating at normal speed or is running slow. Problems such as a bad spot on a commutator or a short or open in the armature also will be obvious in the waveform.
A "good" electric fuel pump waveform will generally seesaw back and forth with relative consistency and minimal variation between the highs and lows. A "bad" waveform will show large or irregular drops in the pattern, with large differences between the highs and lows.

LR3 Denso Alternator YLE500390 pulley view817 viewsNote the DENSO sticker on the side. Denso calls their nominal 150 amp 12 Volt alternator an SC2 design. SC means Segment Conductor which apparently increase the winding density of the stator coil, hence yielding a physically smaller lighter alternator for a given output. I presume the 2 means the second try at getting it right. A Denso part number is 4280003690 for the alternator, (there are others, as below).
Rotation is clockwise and the 54mm diameter pulley has 6 grooves (PV6x54). Count the pulley grooves on both the one you remove and your new one - some replacement alternators seem to ship with 5 or 7 grooves so you might be swapping pulleys.
A previous LR part number was YLE500190 for the older variation of the newer YLE500390 unit.
An additional part number for a factory rebuilt is Nippon Denso 210-0569 for the petrol V8 alternator. Other Nippon Denso numbers include 104210-3690 and 104210-3691. The Lester number is 11206 which relates to another Denso number of 290-5287. WAI uses 11206N.
From 2006 to 2009, the internal regulator is a Transpo IN6349 and of the B circuit type if it can be said that applies to PWM, (Pulse Width Modulated), regulators.
The "regulator" inside the alternator is therefore really not a regulator in the old sense of the term but instead an instruction receiver from the ECM that translates Pulse Width Modulated (PWM) signals into a form that the alternator understands – digital like signals from the Engine Control Module(ECM) into analogue like signals that the windings understand.
