Has anybody noticed there speedo and other needles on the guage cluster jumping around after they shut off their trucks. I noticed mine the other day when I was getting the oil changed. Speedo jumped up to about 10 and the other needles moved just a hair. I also have experienced getting crushed by the driver side seat. (I know why this happened, My 2 ton @ss sometimes hits the seat adjustments.) Just wondering if anyone else has noticed this. Don't think that it's anything to worry about.

I have had the posessed gauges before. I am not worried about it though. Just makes it lookes like it has a heartbeat...even after you shut it down. :lol:

My new boat motor does this after arming to show total run time so you can track it for oil changes. Perhaps this is some sort of feedback for maintenance?

There's a troubleshooting procedure you can do that will check the gauges for any faults. I'll look it up this afternoon in the service manual and post the procedures for you.

ok, here's the procedure to put the gauges into a self-test mode. Just let it run it's course while watching closely for anything that faults or fails and then let us know the results.

I noticed mine doing the same thing pretty much the first time I shut it down. I've seen other vehicles do the same thing so it didn't bother me too much.

It's normal. All the gauges are electronic. The "jump" in the needles after stoping the engine is caused by the power supply voltage bleeding down.
