1971 Mark III Ticking Sound Behind Dash

[stovebolt1]

Howdy;
For the first time today I've started noticing a very fast "tick tick tick tick" behind the dash of my 71 Mark III. Are the Cartier clocks in these known for being fairly noisy? I've changed nothing recently, the noise just started and I'll say it is very prominent. It ticks whether or not the key is in, ignition is on, acc is on, or if I'm holding my breath. The clock hands have never moved since I bought the car and they are still not moving. I'll pull the fuse next and see if that quiets the noise but that constant tick - tick - tick could get very annoying if I'm smoochin' the missus in the front seat.

You could put a paper towel cardboard tube to your ear to narrow down where the noise is. It makes sense its the clock. Possibly frozen gears that finally stripped making that noise. If not clock, then maybe a bad relay somewhere. Is your battery weak or parasitic drain?
