Hi, Len -
Sounds like the overdrive relay to me. When you first turn on the dash
switch, you energize the relay. If the relay is working normally, power is
then supplied to the overdrive solenoid from the relay and the throttle
switch then provides the circuit to keep power to the solenoid regardless of
the position of the dash switch until you step on the gas. If the relay is
not working, then you are getting power to the overdrive solenoid only
through the throttle switch as long as the dash switch is on. Turning off
the dash switch will immediately de-energize the relay, or stepping on the
gas to open the throttle switch contacts. The result is the overdrive
dropping out.
Must be a rash of failing relays out there. I've just received a new one
from Moss to replace mine.

Subject: [Healeys] OD Problem
On the way back from Autumn Classic in San Juan Bautista (CA), my overdrive
began acting strangely.
With the OD switch ON, when I step down on the accelerator, the OD
disengages.
With OD engaged, turning the OD switch OFF causes the OD to disengage
instantly without stepping on the accelerator. I assume (oops!) that the
problem is electrical. Which component, or combination of components, is
most
likely to be the culprit?
TIA
