On my 24V vehicle it's 27.5V so that more-or-less agrees.

If that's right it's a good idea.

I got the current ratings from the car's service manual. I've no reason to suspect anyone had ever changed the alternator. I did have to take it off once to clean up the output connector, which was a bit feeble for the current rating.

I'd suggest you do some tests. There is no need to *regulate* the maximum current. The basic design of the alternator does just that.
Which can take many more miles of driving than charging a flat battery partially to the point where it will re-start the vehicle easily.
If it was putting out 40 volts or whatever other crap you stated earlier it would very soon charge the battery fully. And knacker it.

Occasionally car alternators are used at that sort of voltage output, eg fo r welding. With a battery on load its impossible, at 50A out the battery wo uld limit V to 14-15v. And it would at some point boil, as I know from expe rience with rather less than 50A.
