alfonso,

While I'm certainly not an expert, your regulator terminal ID's don't fit the usual numbering for the proper unit. The typical regulator for use with the alternator is commonly numbered F-2-3-4.

Could you have the wrong voltage regulator? I have linked a picture that shows typical wiring for that 10DN alternator and it companion regulator.

As was mentioned above, you could switch to a 10SI or newer alternator for probably less than the cost of your old alternator and new regulator, and be done with the potential headaches that sometimes accompany the firewall mounted regulator...just a thought!
