The igniter in my Napoleon NPS45 went bad and I tried to install a new one. I had the new one installed and the igniter turned orange and the stove ran good for about 2 minutes and then the fuse on the control board blew. I replaced the fuse and can start the stove manually and everything works. I am guessing that maybe I did not attach the igniter wires properly? When I put in a new igniter how do I know where the 2 wires from the igniter connect to the wire harness? Is one positive and one negative? There does not seem to be any color coding on the wiresor markings to tell one from another. The two wires from the igniter are not connected with the original spade connectors...the 2 wires are just connected with wire nuts. Thanks for any help you can provide. I have ANOTHER igniter coming soon and I want to install this one correctly.
