Gene: Is the ignitor (or another usable one) available to swap out? I'll check the wires for continuity. Does the system use the base of the unit as a ground ..along with the hot (300+ volt) line.. to get the spark? :confused:

Thanks, Jim :D

P.S. I sprayed the contacts with electrical cleaner & lubricant, which seemed to make them worse.. . Was that bad? How do you clean or service them?

Gene: Thanks again... I checked briefly at Home Depot here. They had two stove tops for $650 and $1200! This thing works, but lighting it is annoying for my wife who likes to cook alot. [I'm good at fixing things, so my ego is at stake too! Ha!]. How do I check the insulation? When it doesn't work, it makes a faint sparking noise, like it's sparking inside the module (either new or old module). Maybe I can try replacing the wire (What kind, type or quality is it?), but isn't it part of the spark igniter part? [I could splice with shrink wrap probably..right?]This is aggravating, because I know it has to be something relatively simple.. . It has AC power, the spark wires have continuity, I tried adding a ground (but no improvement), and both igniter modules function the same.. . Yikes! This is too simple of a system to trash a well functioning stove top, cuz I can't get the silly thing to spark. [It worked fine for 15 years until about a month ago, when this intermittent functioning began!] I'll try the alcohol too of course.. . .

Thanks again for all your help! Jim :confused:
