The diagram shows the charging citrcuit.

Ensure the Black wire has continuity between the alternator and starter. With ignitin switch turned, check for battery voltage at the White/Blue wire.

Is the charge indicator showing when engine is running?

The suppression Module is at right front of engine compartnment. See diagram for location and how it looks like.

12.6 v is the battery voltage so the alternator is not charging.

Do you have battery voltage at the White/Blue wire?
