I moved my grill to a new address and was cleaning it up when I noticed that one of the 2 ignitor wires were dangling. The one to the side burner is ok. I can't find or figure out where the other one goed to. It looks like it might have rusted off from whereever it was connected ( I think the collector box ?). My ? if this is correct then is this nothing more than replaceint the collect box, or would it be the collector box and the ignitor assembly? Doesn't look like the wire is detatchable from the ignitor switch. My paperwork really doesn't show it in any great deatail how it should be connected.
