Controllers will have a 15-second delay.)
•
Orange (Blower Motor) wire should have 12Vdc (all the time).
•
Blue (Igniter) wire should have 12Vdc.
• Purple (Fuel Solenoid) wire should have 12Vdc (after the delay).
5 Twist the yellow wires together (once voltage registers) on the orange, blue and purple wires.
•
Orange (Blower Motor) wire should maintain 12Vdc.
•
Blue (Igniter) wire should lose voltage after 15 seconds.
