VSR or Split Charge Diode?

[GHA]

The output of an alternator is controlled by a voltage regulator, the role of which is to maintain a constant output voltage.

Which it apparently does by controlling current. the voltage is determined by the battery in response to the current available. Back where we started. Halcyon's statement was correct .

Careful you don't get run down on a pedestrian crossing by refusing to admit that black isn't white....

Yes, as I put in post 50, the voltage regulator varies the field current, in order to maintain a constant voltage.

You seem determined to want to argue with anyone who'll respond to you, and resorting to personal insults won't get you anywhere, you'll just get ignored.

This is only true when the alternator has finished the bulk stage of charging when the charger changes from a constant current charger to 'absorption stage' when it becomes a constant voltage charger - by controlling the field current.

All simple basic stuff.

So you're saying the regulator doesn't do anything during bulk charging?

N0 - the regulator regulates the current to the maximum the alternator can provide - and what the batteries will accept.

We may be talking at cross purposes here - If we are talking bulk and absorption stages we are of course talking about an external multi stage alternator controller. This is the only way to get batteries properly charged and limit sulfation because the alternator's internal regulator will probably not stay at 14.4v or above for long enough because they have built in temperature compensation that will quickly reduce their output to less than 14v. That's one of the reasons cars can keep running all day and not ruin batteries. Again another thread on this is needed.
