So its -18[SIZE=-1]°C here without the wind this morning. I [/SIZE]Go to start my jeep in the freezing cold and nothing. Alright lets give the battery a nice warm up. So i plug in the battery booster and let it sit there for a few minutes. Okay now i hear a click, but still nothing. I'm guessing its a starter problem because the battery is fully charged and functional. Any ideas of what this can be? :canada:
