Contacts are covered with many layers of dried coolant (it took me 3
years to find this leak - when the engine is warm it evaporates near
the leak and is not easily located - only drops on the snow when cold
and only just drops). I ordered a new connector and will cut the
wires back 6" and solder in new when installing.
