I though it was 136 amps. Not sure why so I could be wrong but that number sticks in my head for some reason.

The 136 amp alternator was used if you got the Trailer Package. Standard was 120 amps. There was a 90 amp also, but don't think it was used on CTD models.

There we go, I must have the trailer package then. I knew there was a reason that sounded like the number.

Remember, these numbers are cold rated. When hot at idle the alternator is putting out significantly less power.
