To be sure, time delay relay, in A01 light package, is only to keep "on" the small tube light in the steering column, not the dome light?

Hey Herve, The time delay relay does power the light fixture on the steering column for the ignition switch and the title light fixture (switch panel). Think of this time delay relay as operating like a one shot turn signal relay. Both relays work by stainless steel contact arms where one is wound with a wire coil. As heat builds up, these contacts heat up, bend and close, then when power is cut, the arm cools and disconnects. The different is the time delay relay will turn on when a door is opened and continues to light those two bulbs after the door closes and does not re-trigger, but only continues on one time for about thirty seconds. Once the door opens again, this sequence starts over again. The delay light relay should be mounted on the steering column with tape as they did at the factory. This serves as a heat sink since this is a thermal driven device. Hanging in mid air can cause this device to burn up rather quickly. To test this relay, unplug and read the impedance between the 12 volt battery input and door jam ground terminals. It should read around -35 Ohms. If there is an O/L reading, the part is dead. Once plugged back in and the door opened and closed, the output terminal should read 12 dcv between and any clean exposed dash metal for a ground. Jim

You are welcome, Herve. Excellent info on here on the A01 time delay relay and what it works on. I am thinking of purchasing one. Are all the relays currently on the market new reproductions? I'd rather trust something new as opposed to something like an NOS relay that has been slowly seizing up for 40 years. Can someone weigh in on this? Thank you! I stock all of the parts for a delay light relay setup. I have NOS 2889565 relays, too. Showing those relays in the picture from the back because the front of the bag is all white. Email or call, if you are interested. Glad to help. Jim

Jim I was rummaging around the wiring harness near the ashtray and I finally found the time delay relay. I used your instructions to test the relay. It measured approx 33 ohms unplugged but I noticed that the relay is nowhere near the column. It is tucked up at the main harness just behind the ammeter. I will release it and tape it around the column as original and then test it with power hooked up to it. This was a very informative post. Thanks again. Lou
