[Healeys] Throttle switch on overdrive function? BJ8

[BJ8 Healeys]

Wes, what you describe is normal.
The only function of the throttle switch is to provide an alternate power
circuit to keep the overdrive relay coil energized independent of the dash
switch, once the dash switch is turned on.  This keeps the overdrive
solenoid engaged when the dash switch is turned off, until the accelerator
pedal is pressed down the correct amount.

The throttle switch normally has no function in initially engaging the
overdrive, just preventing it from disengaging unless you are accelerating.

Perhaps the attached diagram will illustrate it more clearly.

Subject: [Healeys] Throttle switch on overdrive function? BJ8

Hello Folks,

     I have the 2 wires that go to the trottle
switch off. My overdrive goes off and on when I operate the switch on
the dash (as long as I am in 3rd or 4th). Is that normal? I believe
from reading the manual that the throttle switch is supposed to keep
the overdrive engaged until the throttle is off or low. Is it true that
it serves no purpose when engaging the overdrive?

Many thanks
