I have a K 80 that has been showing erroneous RPMs at start up and after the engine has been running for a few minutes .
As soon as the hand data terminal "reads "glow plug test," the HDT reads 64,000 RPMs and then it will read normal during the spin up. After it goes into "running " mode, the engine runs fine for a while during taxi and then , all of a sudden , the engine starts increasing power on it's own without my input . I'll apply brakes and go over to it and hook up the HDT and notice that the HDT reads 0 RPMs and then , the engine will shut down . And ideas on what could be the problem will be greatly appreciated .

Sounds like a bad RPM sensor. They dont fail often but sometimes do fail. Also could be the wiring to the sensor. I would check the wiring and of nothing found send it in the Dirk and he will get it turned real quick for you.

Thanks for your reply. Continuity checked out fine in the wiring.
