Narrative:
Hot-started airplane due to low battery. After start of both engines, activated alternator switches and alternators came on line. Following landing gear retraction on takeoff, radios went dead. Could feel drag due to partially retracted landing gear. After placing gear lever in down position, radios came on enough for me to hear tower but tower could not hear me. Tower advised gear partially down. Did not crank gear down manually because gear position indicator lights were out leaving no visible means of knowing if gear down and locked. If gear collapsed on concrete runway full gas tanks might explode. Also, runway would be OTS. Therefore, decided to land on grass alongside runway. Following full flaps landing on grass, only visible damage was bent propellers. Airplane gear collapsed and plane skidded about 30 ft and came to rest. Suggest visual backup system to gear indicator lights to show when landing gear down and locked.

Title: OFF RWY LNDG MADE IN ANTICIPATION OF PROBABLE GEAR COLLAPSE. EVENT SUBSEQUENT TO PRIMARY ELECTRICAL SUPPLY PROBLEM.
Narrative: HOT-STARTED AIRPLANE DUE TO LOW BATTERY. AFTER START OF BOTH ENGS, ACTIVATED ALTERNATOR SWITCHES AND ALTERNATORS CAME ON LINE. FOLLOWING LNDG GEAR RETRACTION ON TKOF, RADIOS WENT DEAD. COULD FEEL DRAG DUE TO PARTIALLY RETRACTED LNDG GEAR. AFTER PLACING GEAR LEVER IN DOWN POS, RADIOS CAME ON ENOUGH FOR ME TO HEAR TWR BUT TWR COULD NOT HEAR ME. TWR ADVISED GEAR PARTIALLY DOWN. DID NOT CRANK GEAR DOWN MANUALLY BECAUSE GEAR POS INDICATOR LIGHTS WERE OUT LEAVING NO VISIBLE MEANS OF KNOWING IF GEAR DOWN AND LOCKED. IF GEAR COLLAPSED ON CONCRETE RWY FULL GAS TANKS MIGHT EXPLODE. ALSO, RWY WOULD BE OTS. THEREFORE, DECIDED TO LAND ON GRASS ALONGSIDE RWY. FOLLOWING FULL FLAPS LNDG ON GRASS, ONLY VISIBLE DAMAGE WAS BENT PROPS. AIRPLANE GEAR COLLAPSED AND PLANE SKIDDED ABOUT 30 FT AND CAME TO REST. SUGGEST VISUAL BACKUP SYS TO GEAR INDICATOR LIGHTS TO SHOW WHEN LNDG GEAR DOWN AND LOCKED.
