Can an alternator overcharge a battery?

Hijacking?!! Noway mate. On the contrary, you may have just saved my life with a vital tip.
Thought just crossed my mind, since I'm carrying a generator, I should be able to charge the battery as well.
So, I don't think I would carry a spare alternator, rather make sure the existing one is in spotless condition before I take off, and make sure
I don't forget the auxiliary battery and the generator(which I won't, 'cos I need it badly for camping) .

Going back a couple of years ago I was on a trip and my alternator died( gu patrol 4.5 petrol)... I needed to get about 900 km to home without one.... After speaking to people on here and auto electricians in Perth overt he phone I found out the ignition needs about 4 amps per hour to run the patrol once started, so we turned off air con radio all electrics in the car, I put the solar panels on the roof and via an anderson plug connected them to my battery, I linked the dual batteries together and off we went( my batteries were fully charged), when I stopped for fuel I kept the patrol running I indicated at a minimum and let the car slow down over distances instead of breaking... I made it all the way home. I did not have enough power to restart the patrol when I got home but it ran all the the way!
I don't think the solar panels did too much as it was cloudy most the way home typically....

Sorry to hi jack the thread with that little story but thought it was relevant if your alternator dies and this story may help someone else who has a similar situation and gets worried about having to get home...
