that sounds like you have a bad ground. when only one
of the filaments has power it can use the other
filament as a substitute for the real ground. (seems
these light circuits are either connected to power or
ground, not just disconnected from everything. so the
one that isn't turned on is actually providing the
return path for the electric current.) so it might be
kinda dim cause there's the dual resistance of both
elements. but if there is positive being supplied to
both of the elements on the inputs and no ground then
there's no return path for the electricity - no
current = no light. try cleaning everything very well,
but sometimes the bulb is not salvageable, i don't
really know why.
good luck!
