Is it repairable? And what will cause a short circuit? Thank you If the polarity of the solar panel is connected incorrectly, a short circuit will occur. Please correctly connect the polarity according to the instructions. Can you plug charger into cigarette lighter and leave on dashboard? If your cigarette lighter is "cold" (that is, does not deliver power to devices plugged into it) when the car is off, then you cannot charge your car battery via the cigarette lighter. The lighter socket needs to be "hot" when the car is off. Track Page Views WithAuctiva's Counter
