Narrative:

On climb out of mci bound for clt at approximately 8000 ft, noted left auxiliary pump light on with no fuel in auxiliary tank with switch off. Used QRH to satisfy check. On climb out of 15000 ft to FL200, noted left and right red main gear lights on with right gear green light on. Could not get lights out. Flight attendant complained about odor and possible electrical smoke in cockpit and galley (forward). Aircraft seemed somewhat unstable with autoplt off. We elected to divert and land in stl. Callback conversation with reporter revealed the following information: the flight crew found that there was no procedure for the left auxiliary fuel tank switch operating light illuminating with the tank switch being off. As they were arriving at the general conclusion that there was an aircraft electrical problem, the left and right main gear red lights came on along with the right main gear green light. Shortly thereafter, the cabin attendants reported smoke and fumes in the cabin. The flight crew could see stl ahead of them and they decided to go there. After landing, the aircraft was grounded and maintenance started their investigation. The flight crew spent the night there and flew the same aircraft the next day. The crew had an extensive entry about the electrical system symptoms in the logbook, but the maintenance entry was primarily about some loose wiring in the gear lights. The reporter was uncomfortable with the maintenance, but was unable to contact anyone who was familiar with the work that was done on the aircraft. The aircraft was repositioned to mci and this reporter has not flown it since.

Title: AN ACR B737-400 FLC NOTICED THAT THERE WERE SEVERAL INDICATIONS OF ELECTRICAL PROBS DURING THE CLBOUT SO THEY DIVERTED TO AN ALTERNATE ARPT.

Narrative: ON CLB OUT OF MCI BOUND FOR CLT AT APPROX 8000 FT, NOTED L AUX PUMP LIGHT ON WITH NO FUEL IN AUX TANK WITH SWITCH OFF. USED QRH TO SATISFY CHK. ON CLB OUT OF 15000 FT TO FL200, NOTED L AND R RED MAIN GEAR LIGHTS ON WITH R GEAR GREEN LIGHT ON. COULD NOT GET LIGHTS OUT. FLT ATTENDANT COMPLAINED ABOUT ODOR AND POSSIBLE ELECTRICAL SMOKE IN COCKPIT AND GALLEY (FORWARD). ACFT SEEMED SOMEWHAT UNSTABLE WITH AUTOPLT OFF. WE ELECTED TO DIVERT AND LAND IN STL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE FLC FOUND THAT THERE WAS NO PROC FOR THE L AUX FUEL TANK SWITCH OPERATING LIGHT ILLUMINATING WITH THE TANK SWITCH BEING OFF. AS THEY WERE ARRIVING AT THE GENERAL CONCLUSION THAT THERE WAS AN ACFT ELECTRICAL PROB, THE L AND R MAIN GEAR RED LIGHTS CAME ON ALONG WITH THE R MAIN GEAR GREEN LIGHT. SHORTLY THEREAFTER, THE CABIN ATTENDANTS RPTED SMOKE AND FUMES IN THE CABIN. THE FLC COULD SEE STL AHEAD OF THEM AND THEY DECIDED TO GO THERE. AFTER LNDG, THE ACFT WAS GNDED AND MAINT STARTED THEIR INVESTIGATION. THE FLC SPENT THE NIGHT THERE AND FLEW THE SAME ACFT THE NEXT DAY. THE CREW HAD AN EXTENSIVE ENTRY ABOUT THE ELECTRICAL SYS SYMPTOMS IN THE LOGBOOK, BUT THE MAINT ENTRY WAS PRIMARILY ABOUT SOME LOOSE WIRING IN THE GEAR LIGHTS. THE RPTR WAS UNCOMFORTABLE WITH THE MAINT, BUT WAS UNABLE TO CONTACT ANYONE WHO WAS FAMILIAR WITH THE WORK THAT WAS DONE ON THE ACFT. THE ACFT WAS REPOSITIONED TO MCI AND THIS RPTR HAS NOT FLOWN IT SINCE.
