I think you are confused about what overdrive is. When your overdrive system is working properly, pushing the button on the shifter locks the car out of overdrive. If you are doing more than 40mph (or therabouts) you are probably driving in 4th gear, which is an overdrive gear on the AW70 transmission. Pushing the button de-energizes the solenoid, which disengages overdrive; that means you are in 3rd gear.

Keep in mind that the relay grounds the arrow light - it is always supplied power through the cluster. Whether you have OD or not, if the relay is clicking but the arrow is not coming on, I would look first to the single wire on the back of the gauge cluster, red/yellow I believe, that connects to the lower right hand side. That should be the ground path for the OD Off light.
