Thanks Jim, but I hope Dave does not see those two first paragraphs... because they seem very much like my statement "creates too much resistance ,like a corroded wire/connector/frame will cause excess electrical flow and blow a fuse. " LOL

Concerning my 'inverse relationship'.....
I have located that old Hot Rod Magizine tuning manual and it says ...

" A generator does not put out full voltage all the time. One of the characteristics of an automotive generator is that it cannot put out maximum voltage and maximum amperage at the same time. when it is putting out maximum current or amerage, the voltage fall to a comparatively low level. When the generator is putting out maximum voltage , there is practically no current flow at all. "

This is where I got the mental image of inverse relationship...
Perhaps this does not apply to alternators and remembering it is just showing the age of the cars I started out working on.... LOL..... Greg
