Document - Elec - Retrofit To 90A Alternator

Technical Document 2310306 contains general instructions on using the 2340155 (90A) in place of the 2328603 (51A) unit for purpose of upgrade for more amperage capacity. These instructions cover the differences between these units physically and electrically, as they have different properties for wiring and use from one another, but physically mount the same on the engine and use the same pulley.
