Not normal. The OD should not do anything until you reach approx 20 mph. At that time if all the other switches are ready governor closes OD contacts to ground, relays actuate, light comes on, and you should go into OD when you let your foot off the gas for an instant.
The EC system is totally separate from the OD with exception of the governor. It should be active until approx 20 when governor opens the EC contacts to ground. When working, if EC switch is on and ground is present, when the engine is started and vacuum becomes available if you are holding the clutch pedal depressed it should feel like it drops away. On some cars if the clutch pedal is out it will move to the floor on its own. That last bit depends on a piece of linkage and springs so not all pedals visually move. A combination of valves and switches use accelerator position to determine when to engage or disengage until the governor cuts the operation at about 20mph. After 20mph EC will be inactive unless you are in third and the shift lever is moved slightly to downshift.
It almost sounds like the wires at the governor are swapped or perhaps the OD wire to governor has shorted. As a first step I would suggest you verify the wiring on the back cover on the governor. It will probably be hard to see colors but the OD wire should be coming from one of the terminals on the kickdown switch and should go to the AD terminal on governor that is an exposed rivet connection -- sort of in the middle of cover. Checking with an ohmmeter from that governor wire to chassis (disconnected to OD), there should be no connection to ground at this time. Hard to check the other direction unless various things are disconnected because of some connections that could falsely indicate a ground.
The EC wire comes from the accelerator switch and connects to a wire on the governor that enters a raised molded portion on the cover. The actual wire connection on the cover is probably covered with tar. If the wire to EC is disconnected the wire entering governor should be grounded with car at rest.
If the wires at governor check out OK let us know and will help troubleshoot farther. Here are schematics for the R9 and EC. As you can see the only common point is the governor. If EC starts working when you push OD knob in it sounds like some wiring could have been intermixed.
