So I bought a battery from ebay new for the dt as mine was stolen, connected it up and it worked perfectly! Left it connected so the alarm was working then went home, came back to the bike and nothing on the alarm...then I thought maybe it was dead...alarm or the dodgey ignition had drained it. So put my trickle charger on and it was saying that the battery was full, checked with an alt meter and it was dead (so i assumed my charger was kaput. Gave my bat to my boss to charge with his charger at home and it wont charge...WHAT IS THIS WITCHCRAFT??
