Only the voltage regulator. The ELD sends a signal to the ECM informing the ECM as to what the electrical load is at any particular time. The ECM then makes the decision whether or not to cause the voltage regulator to allow full charging-voltage.
Besides its communication lines to the ECM and VR, The ELD has only an inductive connection to the rest of the electrical system, much like a hand-held Fluke voltage tester.
The ELD is meant to increase a vehicle's gas mileage by reducing the drag load that the alternator normally applies. It is only installed on US-market cars, because the US is the only country in the world with gas-mileage regulatory targets that automakers must meet.
Further reading of my documentation seems to suggest that a blown fuse can cause problems that might be blamed on the ELD. It would behoove the OP to check each and every fuse in both fuse boxes.
thank you for taking the time to explain that. wow. the sensing end of an intelligent ammeter...
