Narrative:
Captain started second engine at hold short and immediately accepted a takeoff clearance. PF, (right seat), was directed to 'go.' he added power and on rotate realized that the aircraft was not trimming electrically and was under partial electrical power. He elected to land as soon as possible visually. The captain incorrectly responded 'negatively' while meaning 'affirmative' via the 'identify' feature of the transponder (to tower inquiries). First officer put in 7700 to clear up confusion and landed the aircraft. On clearing runway, first officer found battery start switch in wrong (start) position, causing electrical power loss. Causes of incident: rushing, not completing takeoff checklist or verifying completion.

Title: FLC TKOF WITH THE ENG START SWITCH IN THE START POS RESULTING IN A LACK OF ACFT ELECTRICAL PWR AND A RETURN TO LAND TO DETERMINE THE PROB.
Narrative: CAPT STARTED SECOND ENG AT HOLD SHORT AND IMMEDIATELY ACCEPTED A TKOF CLRNC. PF, (R SEAT), WAS DIRECTED TO 'GO.' HE ADDED PWR AND ON ROTATE REALIZED THAT THE ACFT WAS NOT TRIMMING ELECTRICALLY AND WAS UNDER PARTIAL ELECTRICAL PWR. HE ELECTED TO LAND ASAP VISUALLY. THE CAPT INCORRECTLY RESPONDED 'NEGATIVELY' WHILE MEANING 'AFFIRMATIVE' VIA THE 'IDENT' FEATURE OF THE XPONDER (TO TWR INQUIRIES). FO PUT IN 7700 TO CLR UP CONFUSION AND LANDED THE ACFT. ON CLRING RWY, FO FOUND BATTERY START SWITCH IN WRONG (START) POS, CAUSING ELECTRICAL PWR LOSS. CAUSES OF INCIDENT: RUSHING, NOT COMPLETING TKOF CHKLIST OR VERIFYING COMPLETION.
