Recently I came across a honey well pilot burner with a honeywell s86 spark module. After pilot burner lights, main valve opens and pilot burner keeps on ticking for quite a while. Furnace opperates properly. Is this a problem with the module or the flame sensor on the burner? I suspect it's a problem with the module, but am not sure. Also, is there anyway to test the electrode on the pilot burner for proper flame detection, possibly with a milivolt meter or miliamp meter?
