Hi, Kirk. The positive end of the battery should face you, when you install it. Before you rush out to buy a new ignition module, check all the wiring from the module to to each spark ignite. You want to make sure that all wiring is in intact, that the ground wire for the module is attached to the grill frame and that the spark igniters are clean & free of grease.
If you find you need to replace the igniter module, you can find it at the following link.http://www.appliancefactoryparts.com/search/partinfo.php?partsID=496283&modelsID=124200
Hope this helps you. Don't forget you can match light the burners if necessary, until the igniter module is replaced. Happy Grilling!!
