Air carrier medium large transport had filed slc-mlf-J107-hec. Pre departure clearance was mlf 2 SID mlf-bld as filed. Failed to reprogram FMC. Having problem with the electrical system and failed to double check the raw data with FMC. Controller vectored to cleared routing.

Narrative:
Filed flight plan was slc-mlf-J107-hector. The clearance was mlf 2 mlf-bld as filed. We were dealing with a recurring generator malfunction when we received the pre departure clearance. The first officer and I noted the difference between filed route and route clearance but I neglected to make the appropriate route adjustment in the FMS. After takeoff we received 2 vectors to intercept the departure. I armed the navigation capture mode and captured the outbound route (slc direct mlf). I did not xchk the raw data information so I did not notice the error. (The VOR radio and course were set correctly for the mlf 2 departure.) the ATC controller made us aware of the error and issued a vector for on course. I think a partial solution for this is for our operations department to file for the route ATC prefers rather than one that is never issued. This was typical of most incidents where a mechanical problem caused a distraction so that another task was ignored.

Title: ACR MLG HAD FILED SLC-MLF-J107-HEC. PDC WAS MLF 2 SID MLF-BLD AS FILED. FAILED TO REPROGRAM FMC. HAVING PROB WITH THE ELECTRICAL SYS AND FAILED TO DOUBLE CHK THE RAW DATA WITH FMC. CTLR VECTORED TO CLRED ROUTING.
Narrative: FILED FLT PLAN WAS SLC-MLF-J107-HECTOR. THE CLRNC WAS MLF 2 MLF-BLD AS FILED. WE WERE DEALING WITH A RECURRING GENERATOR MALFUNCTION WHEN WE RECEIVED THE PDC. THE FO AND I NOTED THE DIFFERENCE BTWN FILED RTE AND RTE CLRNC BUT I NEGLECTED TO MAKE THE APPROPRIATE RTE ADJUSTMENT IN THE FMS. AFTER TKOF WE RECEIVED 2 VECTORS TO INTERCEPT THE DEP. I ARMED THE NAV CAPTURE MODE AND CAPTURED THE OUTBOUND RTE (SLC DIRECT MLF). I DID NOT XCHK THE RAW DATA INFO SO I DID NOT NOTICE THE ERROR. (THE VOR RADIO AND COURSE WERE SET CORRECTLY FOR THE MLF 2 DEP.) THE ATC CTLR MADE US AWARE OF THE ERROR AND ISSUED A VECTOR FOR ON COURSE. I THINK A PARTIAL SOLUTION FOR THIS IS FOR OUR OPS DEPT TO FILE FOR THE RTE ATC PREFERS RATHER THAN ONE THAT IS NEVER ISSUED. THIS WAS TYPICAL OF MOST INCIDENTS WHERE A MECHANICAL PROB CAUSED A DISTR SO THAT ANOTHER TASK WAS IGNORED.
