Seems like it should not matter, but till now I have never had to do it. Will it make full power, any power at all?

It will generate electricity just as well, only concern I see is that alternators have a built in cooling fan. It will move less air if spun the reverse direction so it will not cool as well. Long runs at high power may cause early failure.

Most I have seen use a radial blower that looks like rotationYeah, I was planning on making a new fan for the reverse rotation if as I suspect It will generate in reverse rotation.
Can you link to these special CHP alternators? I've never seen such.Alternator so no difference but some have clutches in them so they can freewheel if engine speed changes quickly.
Ford police cruisers that CHP uses have these as the standard ones would break the shafts.

GregSY, .............Has that new batch of foil hats come in yet?
It will work but since it is backwards, it will take power out of the atmosphere, pull it through your headlights and such, then send it to your battery for storage. Then, when you really need it, it will go from your battery into your alternator stator where it will spin the rotor to send power through the belt into your engine's crankshaft. At that point, it can either be used to help propel the vehicle more faster, or it will be converted via the fuel system into raw gasoline which is then put back into the fuel tank for later use. It's all just energy conversion, you see.
As others have said, it will work. The only caveat is that it is best to replace the brushes if using a used alternator.
The brushes take a set as they wear in and don't make proper contact when reversed. The problem is that they still make contact but only in a small area leading to possible arcing.
They also do make cooling fans for either rotation. The fans do work better in the direction they are made for but less efficient when reversed.

The old Indy Cars that ran Buick and Chevy V6 stock block engines used a Delco alternator that was driven by a speedometer cable on steroids. It had an over run clutch in it as well as the engine speed would change faster than the alternator could and the cable would tie itself in knots.
