I have a 1964 GMC C1000 pickup with the original external alternator. I have a CS style DL1490-6-1 140 amp alternator that I picked up a few years ago at a salvage yard for a different project that ended up on the shelf.
I have searched the forums, but all I have been able to find is how to wire in a SI alternator, nothing on a CS style alternator.
Any and all help is greatly appreciated.
