I've been mulling this over, and decided that what I think you mean is
impossible. Are you sure the ammeter shows charge on the other car? Many
of the directions found on the web and other places say to connect the
alternator such that the charge does not appear on the ammeter; since the
alternator can put out more than the 30 amps that the stock ammeter is
designed to handle.
Some alternators seem to rely more on the current through the warning light
than others do. For my alternator conversion, I found that the stock
warning light did not pass enough current for the alternator to reliably
start working at modest rpm. After I got tired of having to rev to 3500 rpm
to "wake up" the alternator, I added a resistor across the warning light to
pass more current. Don't recall the value offhand, but I can get it tonight
if you want.
