Flight Crew Human Performance
On climb out; left generator 'off' light came on. After getting to a safe altitude the first officer completed the checklist. Just before checklist completion; the left 'CSD oil press low' light came on. We went to that checklist which ultimately had us disconnect the CSD. After the procedure; it was determined that the CSD did not disconnect. We called dispatch who patched us through to maintenance. Maintenance recommended that we shut down the engine and land as soon as possible due to the possibility of engine damage from a non-disconnected CSD. We were about 30 mi from ZZZ so we declared an emergency; shut down the engine and descended into ZZZ. In order to lose altitude on final approach; I s-turned; slightly exceeded 30 degrees of bank and were not stabilized by 500 ft VFR. We landed overweight. In hindsight; once the engine was shut down the possibility of engine damage may have dropped to the point where a 270 degree turn for altitude loss may have been the better choice; leading to a more stable approach and landing.

Title: AN MD80 FLT CREW EXPERIENCED LOW CSD OIL PRESSURE AND ATTEMPTED TO DISCONNECT THE CSD; BUT IT FAILED TO DISCONNECT. THEY CONSULTED WITH MAINT; DECLARED AN EMERGENCY; AND DIVERTED TO THE NEAREST SUITABLE AIRPORT.
Narrative: ON CLBOUT; L GENERATOR 'OFF' LIGHT CAME ON. AFTER GETTING TO A SAFE ALT THE FO COMPLETED THE CHKLIST. JUST BEFORE CHKLIST COMPLETION; THE L 'CSD OIL PRESS LOW' LIGHT CAME ON. WE WENT TO THAT CHKLIST WHICH ULTIMATELY HAD US DISCONNECT THE CSD. AFTER THE PROC; IT WAS DETERMINED THAT THE CSD DID NOT DISCONNECT. WE CALLED DISPATCH WHO PATCHED US THROUGH TO MAINT. MAINT RECOMMENDED THAT WE SHUT DOWN THE ENG AND LAND ASAP DUE TO THE POSSIBILITY OF ENG DAMAGE FROM A NON-DISCONNECTED CSD. WE WERE ABOUT 30 MI FROM ZZZ SO WE DECLARED AN EMER; SHUT DOWN THE ENG AND DSNDED INTO ZZZ. IN ORDER TO LOSE ALT ON FINAL APCH; I S-TURNED; SLIGHTLY EXCEEDED 30 DEGS OF BANK AND WERE NOT STABILIZED BY 500 FT VFR. WE LANDED OVERWT. IN HINDSIGHT; ONCE THE ENG WAS SHUT DOWN THE POSSIBILITY OF ENG DAMAGE MAY HAVE DROPPED TO THE POINT WHERE A 270 DEG TURN FOR ALT LOSS MAY HAVE BEEN THE BETTER CHOICE; LEADING TO A MORE STABLE APCH AND LNDG.
