This bulletin cancels Dealer Service Bulletin 87-54 (Section 6D) dated January 1987. Bulletin 87-54 Reissue provides part numbers for replacement
generators that include the improved voltage regulator.
CONDITION:
Under certain operating conditions, the voltage regulator may become inoperative causing either a no-charge or full-charge
condition. A no-charge can lead to a no-start condition, while a full-charge can lead to excessive battery charging, which can
damage the battery.

An improved voltage regulator, P/N 1116423, has been released. Replace the original regulator with the new regulator. The
new regulator can be used for any 1986 Caprice, Camaro, or Monte Carlo or 1987 Caprice or Monte Carlo, except the 120
AMP used on Chevrolet police and taxi option only.
