Counting engine running time

in 912 / 914 Technical Questions 13 years ago
Anyone who know were to attach an hourmeter on 912 ULS.
We now have it connected to the master switch and would like just to count when engine is running

    Hobbs time is a better measure of actual engine time. An hour meter is usually around 20% off as it may vary with engine rpm. Runs slower at idle and faster at higher throttle settings. Hobbs time should be more accurate because it should be setup to read when the engine develops 15 psi or more and runs constant.
