Even if a glow igniter works with DC curent, if there is a loose conection or wire, there might be some sparking at that point...now a spark covers the entire rf spectrum, wich might cause your radio trouble...
Hey.....another factor........[8D]
As I attached the igniter clip to the glow plug, it would spark. you can see it and hear it crackle.[X(]
If it was wiggled, it would do the same, same as if the engine were being started. Tried another igniter clip and though it still sparked and crackled if you wiggled it, not even close as the other one. Caused much less problem and concern.
