Alternator identification/wiring

I have purchased a CD from Big Dean, a service manual, and searched forums and internet but I cannot find the correct alternator wiring I have on my MF30 industrial with 4cyl perkins diesel. It does not have a generator and has a 4 wire delco-remy (10dn?) alternator with battery and ground posts as well as F and R wires and uses an external regulator. Some schematics look similar but either have a generator or different alternator configurations. I want to make sure I have things correct as some wiring has been altered with apparently a new installation of a light and horn switch. I believe it is incorrectly charging all of the time now. THANK YOU for any helpful identification and related information provided!
