well, I charged up my igniter and unscrewed the cap (so the battery is exposed) and I realized that the negative side of the single cell battery pointed towards the gauge and the positive to the tip thing where it was connected to the charger. My question is: Does it matter which side is positive and negative? Please help me out because I don't want a 12 hr charge to go to waste =/ I tried switching the battery around and the glowplug would still glow regardless of the position of the positive and negative sides sooooo.. iono.

Please help! Thanks.
