Is the (voltage?) range spec for the high pressure oil warning circuit
on L board really so sensitive that a presumably small increase in
resistance in a badly corroded high pressure brown ground path wire
will cause the alarm to sound? Or maybe that badly corroded wire sends
a "dirty" or inconsistent ground path which in turn causes alarm to
sound?
