CS-144 Generator - Rectifier Bridge Usage
Number 87-8-6 Date 10/86Subject: USE 1989774 RECTIFIER BRIDGE ON CS-144 GENERATORS
1987 BONNEVILLE
When replacing the rectifier bridge in CS-144 generators, it is very important to use the correct replacement rectifier bridge, which currently is part number 1989774. This bridge uses special avalanche rectifiers which protect the generator and other vehicle electrical components from high voltages, including transient voltages.
While the 1988976 rectifier bridge, for the 17SI generator, is the same in size and shape as the 1989774, it is not the same electronically, and must not be used in CS-144 generators. Damage to the generator and other vehicle electrical components may result.
When replacing electrical parts on vehicles with electronic components, it is necessary to refer to the parts lists to determine the correct replacement part number. Do not use substitutes.
