Bulletin No. T-88-33
File in Group 6D
Number 36
Corp. Ref. No. 749102R

Date Oct. '87
SUBJECT: RECTIFIER BRIDGE FOR CS-144 GENERATORS

MODELS AFFECTED: 1986-88 DE VILLE AND FLEETWOOD 1986-88 ELDORADO AND SEVILLE 1987-88 ALLANTE


Some 1986-88 DeVilles, Fleetwoods, Eldorados and Sevilles, and 1987-88 Allantes may experience a condition of the "no charge", "battery no charge", or "battery volts low" light illuminated. When standard charging system diagnosis leads to rectifier bridge replacement, the correct part number to use is P/N 10467052.

When replacing the rectifier bridge in CS-144 generators, it is important to use the new part numbers listed below. The bridge has a new heat sink design capable of greater heat dissipation and uses special avalanche diodes which protect the generator and other vehicle electrical components from high voltages, including transient voltages.


FROM TO

1986-88 DeVille, Fleetwood, 1989774 10467052
Eldorado & Seville

1987-88 Allante (No Change) 10467052 10467052


While the 1988976 rectifier bridge for 17SI generators is the same in size and shape as 10467052, it is not the same electronically and must not be used in CS-144 generators. Damage to the generator and other vehicle 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.

For warranty purposes, use Labor Operation J4080 at .8 hour with an add of .1 hour to replace the rectifier bridge.
