There is an error in the user manual, which I confirmed with Char-Broil’s customer service rep.  There are 2 wires running from the igniter through the the left-hand handle.  The wire with a flat metal circle at the end is the ground wire, NOT the igniter wire, and the longer wire with a thin ring at one end is the igniter wire that fits into the white tube projecting from the bbq box/burner, NOT the ground wire.  Surely this goof has been spotted by other purchasers In the past!  I am not impressed.
