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?

Thanks yes 12.6v between alternator and starter; blue/white 12.6v trouble light on message 'battery not charging' I should get 13.6+ back in the battery compartment? Right battery is not charging. Where is the suppression module located? What does it look like?

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?
