Hi there, went to go to work one morning turned car over two or three times, battery went dead, jump started no problems,this has happened on four more occassions now. The last time i got a mechanic to jump start me, he took a reading off of the battery and it was over 14v, went to turn her over it dropped rapidly to about 9 -dead. Jumped the truck reading stayed at about 14+v, turned everything on, hazards, lights, fan, readings all over the place, tgurned everything off, back to about 14v again. Turned engine off slight drain on the volt meter, mechanic sems to think it's draining back through alternator, does this mean alternator on its way out. I'm a bit nervous now driving with lights and fan on and then turning engine off in case it fails to start again. Battery is a year old and sems to be charging when the engine is running and nothing else is on, also i've been told rightly or wrongly that the truck should have a dry cell battery fitted? before an expensive garage trip any advice or thoughts would be most welcome
