Perkins 4-154 Alternator T1 and T2 which wire?

[FLmorgansailor]

Working on a Morgan Out Islander 42, 1985, with a Perkins 4-154. My question is on the alternators 2 wire plug, T1 and T2. I am not sure which wire is goes to T1 or T2. I believe that the exciter is T1 and T2 requires 12V all the time. One wire comes from the oil pressure sender not the ignition switch. I believe that that the oil pressure switch wire has 12 V all the time. Cant seam to find where T2 comes from. The Morgan semantics are of little help and the drawing is not so good. I see that one wire has a 22- 50 Ohm resitter and not a lamp.

Any ideas on figuring this out would be very helpful. Would you know it the oil pressure sender wire goes to T1 or T2? Or where the other wire comes from or goes to?

Fairly certain you have a Delco Remy alternator that was standard equipment on a Perkins.

If so, I've attached the installation guide to the 10, 12 and 15SI alternators which explains where T1 and T2 connections are made.
