Good guess...the "solid wire" is a coaxial thermocouple. One end sticks into the flame and the other end screws into the gas valve. When the t/c is in a flame, it generates a few millivolts which (astonishingly) is enough to hold the gas valve open after you open it by pushing the button. The connection to the LED panel is a single wire from the gas valve, goes (IIRC) to an inline plug a foot or so away from the LED panel connector. david David Beierl - Providence, RI http://pws.prserv.net/synergy/Vanagon/ '84 Westy "Dutiful Passage" '85 GL "Poor Relation" |
