(EDIT) No longer satisfied with this purchase. Sent it back for a refund and bought a different brand. The detonator failed at 3:00 this morning. I did a continuity/resistance test on the wiring harness first. No proof. Pulled it out to inspect and it was clearly a tear. See photos. (EDIT) My last igniter lasted great for 14 years so it worked very well. This new Goodman Amana igniter looks exactly like my old Norton, has the same part number, same connector and is said to be made of a stronger material. If it lasts at least half as long as the old one, I'll be a lucky tourist. Especially for the great price and fast shipping!
