2002 V70 2.4 petrol non-turbo has flat battery and cannot open Tailgate. Also has alternator problem – not safe to jump start as alternator 'whines' and when last driven, car showed warning: "El current high STOP SAFELY". Initially i want to access actual battery by finding a way to open tailgate but without compromising electrics system. I have a GOOLOO lithium jump start and can start engine but engine soon stops – maybe because the 'whining' alternator is not charging battery? After connecting the GOOLOO jump start, is it safe to try and use the car key's remote control to 'unlock' the tailgate but without starting the engine? Any other way to unlock the tailgate so I can check / remove battery? 5 seater so no key lock on tailgate. Thanks for reading.
