I'd be helpful if you listed the part number of each item. In the case of the alt, all numbers on the label.
I ran an alt & Transpo reg sold by Mark Landoll back in the mid-'90s, before moving to internally regulated alts. I *might* be able to find his hookup diagram, but Transpo makes a LOT of different regulators.
If you prefer, you can email me pics of the alternator label, the back showing the terminals, and a pic of the Transpo regulator. (I certainly won't put you through the hassle of linking pics on this forum.)
Were both sold by Airtec, or are you just trying to use their diagram?
A shot of the wiring diagram would be good, too, to see if all the stuff 'matches up'.
