Hi does the tab you ground to stop the engine make electric when the engine runs?   My hrc7013 mower has an hour meter that does work. The engine  does not have charging coils under the flywheel. Where does it get its power?

Thanks I know that. It has an hour gauge that works. It has no electrical system. Where does the hour gauge get it’s power?

It may have a a button battery or run off the inductance created by the plug wire. If it displays while the engine is stopped it has a button battery.

It would have to pick operating power from running engine so that it records running time.

This is 20 years old, I’m sure that a button battery would be dead by now.  Plus it is the type of gauge that the number turn.

Ok where does it get the power from? Only wire that goes to the dashboard is the kill wire from the magneto
