Anyone know the wiring harness on an HDJ81 (1994) well enough to say what would cause the speedo to almost always read zero for the first five minutes of driving, whenever the rig was parked for a few hours?

The odometer and trip meter tick over accurately from the get go.

Thanks,

A.
 
I chased a similar problem for a while. Had to enlist the help of a real Land Cruiser mechanic in the end. Ended up being the speedo in the dash cluster itself. Replaced it with a new (and then recalibrated by a specialist, $$) OEM speedo and problem solved. It was messing with some other electrical things too, IIRC. The best part was that I got a new bulb for my "D" indicator...

Mine seems to be perfectly consistent after the first 5 minutes. Did you experience the same?
 
I think so, but after a bit it just quit completely. Luckily my tach still worked and I knew my speed due to rpm! Did a couple thousand miles like that.
