RE: [DML] Re: Fans go on with ignition key...

David,

This subject brings up a design defect that exists with the AC cooling fan
circuit. In most AC systems the condenser fan runs continuously whenever the
cooling function is selected. Years ago I modified several DeLorean AC
systems to operate with these characterizes. There are three distinct
advantages to this modification.

[NOTE see http://www.dmcnews.com/Techsection/coolfan.htm]

A. Like other AC systems the condenser will operate more efficiently with
continuous airflow during compressor off cycles especially when the car in
not moving.

B. There is less stress on the electrical system from high current surges
produced when the fans are switched on.

C. Creates a "cooling fan continuous on" function in the event of a coolant
*over-heat sensor problem.

*Defective otterstat, low coolant level, trapped air in coolant lines.

It is "not a good thing" to have the fans run constantly. You will overheat
the wiring and prematurely wear out the fan motors. The otterstadt switch
should only turn the fans on when the coolant gets hot enough and then with
the fans running it should quickly cool the coolant enough for the fans to
shut off for a while. This is very dependant on the ambient temperature.
Even when you turn on the A/C, the fans are supposed to cycle on and off
when the compressor cycles on and off.
