1986-87 RIVIERA
When replacing the rectifier bridge in CS-144 generators, it is very important to use the correct replacement rectifier bridge, which currently is Part No.
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 17SI generators 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.
