Should the alternator start charging the battery straight away when I start a 2005 liana 1.6
Bought a Suzuki 1.6 liana 2005 had a dead battery got a second hand one everything seemed fine then got home and it totally shut down on me! Next morning jump started it and managed to get it to a mechanic who said had a bad alternator bought one from eBay fitted it in but that one wasn't charging too! So frustrated bought a new one but was told need a new battery so got a new one the car was on for an hour with lights on and everything and everything was fine had it for two days went all over with it no check lights the car seems fine .. This morning had a chat with a naighbor who thought of checking the alternator with his avometer and said its not charging!??! Shocked I went straight back to the mechanic who told me not to worry it does charge but might not give a reading at the spot??? Is that true?
