Just took delivery of my new Ferris 2100. I read in the owners manual that the hours meter only runs when the P.T.O. is engaged. This does not reflect correct run time on the engine. To track run time for engine service I would like to wire the hour meter to the ignition switch rather than to the PTO switch. Question; Has anyone done this? If so how did you re-wire the hour meter....Thanks in advance.....
