C210 aircraft needed an electrical external power for starting, FBO claimed there was none available, FBO mechanic tried jump from his truck (12 volts) which caused burned wiring. It wasn't discovered until takeoff roll when aircraft had complete electric failure. Reporter taxied back, mechanic replaced wires, proper power cart was found and flight continued normally.

Narrative:

On mar/tue/97 at approximately XX00 local, I prepared my T210R for departure from bos. The aircraft would not start, so the FBO was requested to supply external power. They denied having the requisite 28 volt source. The FBO's mechanic was dispatched. The mechanic hooked up jumper cables from his truck battery (12 volt) directly to the aircraft battery, bypassing the aircraft external power source. Upon attempting to start the aircraft, a puff of smoke entered the cockpit from the vicinity of the master switch. The mechanic checked for damage but could not find any. The FBO was re-queried regarding their external power, and it turned out that they indeed had a 28 volt gpu. After some initial failures, the aircraft was started and electrical system and avionics appeared normal. On takeoff, the aircraft had a complete electrical failure. The takeoff was aborted and aircraft taxied back to the ramp. The same mechanic reinspected and discovered burnt insulation on wires from the master switch. He replaced the wires and everything seems back to normal. Mechanic made no logbook entries.

Original NASA ASRS Text

Title: C210 ACFT NEEDED AN ELECTRICAL EXTERNAL PWR FOR STARTING, FBO CLAIMED THERE WAS NONE AVAILABLE, FBO MECH TRIED JUMP FROM HIS TRUCK (12 VOLTS) WHICH CAUSED BURNED WIRING. IT WASN'T DISCOVERED UNTIL TKOF ROLL WHEN ACFT HAD COMPLETE ELECTRIC FAILURE. RPTR TAXIED BACK, MECH REPLACED WIRES, PROPER PWR CART WAS FOUND AND FLT CONTINUED NORMALLY.

Narrative: ON MAR/TUE/97 AT APPROX XX00 LCL, I PREPARED MY T210R FOR DEP FROM BOS. THE ACFT WOULD NOT START, SO THE FBO WAS REQUESTED TO SUPPLY EXTERNAL PWR. THEY DENIED HAVING THE REQUISITE 28 VOLT SOURCE. THE FBO'S MECH WAS DISPATCHED. THE MECH HOOKED UP JUMPER CABLES FROM HIS TRUCK BATTERY (12 VOLT) DIRECTLY TO THE ACFT BATTERY, BYPASSING THE ACFT EXTERNAL PWR SOURCE. UPON ATTEMPTING TO START THE ACFT, A PUFF OF SMOKE ENTERED THE COCKPIT FROM THE VICINITY OF THE MASTER SWITCH. THE MECH CHKED FOR DAMAGE BUT COULD NOT FIND ANY. THE FBO WAS RE-QUERIED REGARDING THEIR EXTERNAL PWR, AND IT TURNED OUT THAT THEY INDEED HAD A 28 VOLT GPU. AFTER SOME INITIAL FAILURES, THE ACFT WAS STARTED AND ELECTRICAL SYS AND AVIONICS APPEARED NORMAL. ON TKOF, THE ACFT HAD A COMPLETE ELECTRICAL FAILURE. THE TKOF WAS ABORTED AND ACFT TAXIED BACK TO THE RAMP. THE SAME MECH REINSPECTED AND DISCOVERED BURNT INSULATION ON WIRES FROM THE MASTER SWITCH. HE REPLACED THE WIRES AND EVERYTHING SEEMS BACK TO NORMAL. MECH MADE NO LOGBOOK ENTRIES.
