Got a problem with my GQ fellas any auto sparkies on here? It sat for a fortnight and the battery was flat as a pancake and I put it down to the cold weather so I charged her up. That's when the saga began as I thought I had a crook charger. Got a newie (Thanks Aaron) and charged her up but it was flat two days later again so decided the battery had given up the ghost. This was considered strange as it was only 14 onths old and it's a good Century, never been flat before now? Got a new Century and put that in and two days later F*&K me swinging it's dead flat again ffs..... I noticed there is a small spark from the terminal when reconnecting and now the volt gauge isn't showing much above 12.4ish when charging. Would there be a crook diode in the alternator that is allowing it to drain the battery and if so how do I determine this, as in what could I disconnect first off the alternator and then reconnect the battery and let it sit for a couple for days and see if it goes flat again? I've tried disconnecting the alt and the multi still shows a .5A discharge. Anyboby else got some other way to test the alternator to see if the current drain is through there?
