Re: New alternator, 4 regulators, still can't find voltage draw

A 1973 should be internally regulated 10si. Do you have an external regulator? all my application catalogs list 1973 as internally regulated alternator. when you got the new alternator did it look exactly like the original and hook up the same way or was the two wire plug different?
