The tc is not connected to the 12V AFAIK. It is it's own separate
circuit; fridge case provides - and tc provides + .
But then I ain't no expert! ;)
I've read that the flue has a great effect on whether or not the
fridge stays lit while driving. This prompted me to inspect and adjust
manifold last time fridge was out. (see pic I linked to) AFAIK, the
manifold seals to the flue plate and all is assembled correctly. This
is why I suspect that if air turbulence is introduced in combustion
chamber while driving, it might be enough to "wave" the flame away
from the tc thus allowing current to cease its flow and the safety
switch is allowed to return to the closed position.
That's the standing Far Fetched Theory as of now. I have several others. ;)
Neil.
