[Healeys] Overdrive wiring question

[Bruce Steele]

Yes, I removed the ground wire.  It could be possible that the relay was
grounding out elsewhere; I'll need to check that possibility.

Bruce - random thought:

 

You indicate below [#2] that you removed the ground from the relay.  I
assume you mean to say you removed the ground __ wire__ from the relay.  

 

Is it possible the relay was still grounded directly to the body?

A couple of other factors:

1.    The dash switch is not defective; it tests fine.

2.    Removing the ground from the OD relay (terminal W2) had no effect;
i.e., the solenoid still engaged when the lever was moved to the 3rd/4th
position, indicating to me that the relay was not engaged and thus holding
the relay points closed.

After installing the new wiring harness, I encountered a puzzling situation.
With the engine off and the ignition on, the OD solenoid would engage when
the shift lever engaged the transmission switch irrespective of the position
of the dash switch.  That is, the solenoid would engage whether the dash
switch was on or off.  Further, if I depressed the accelerator, thus opening
the throttle position switch, the solenoid would NOT engage under the same
conditions.  Hence, it seems that either the OD relay was engaged by the W1
terminal being energized or somehow the C2 terminal was energized.
Unfortunately I caused a short in the throttle switch damaging my harness
before I could trace this.  Any thoughts?
