WayneL Posted October 8, 2015 Share Posted October 8, 2015 Has anyone got a wiring diagram solution to connecting an hr meter to a rotax 503 so it only runs when the engine is running. I have the rotax reg/rectifier. Wayne Link to comment Share on other sites More sharing options...
thommo Posted October 8, 2015 Share Posted October 8, 2015 How about a tiny tach? Hour meter when engine runs as well a Tacho. 2 Link to comment Share on other sites More sharing options...

Good wiring diagrams but 503 one is for no battery in circuit, 582 diagram does not show an HR Meter in circuit. How about a tiny tach Thanks Thommo, that would work! Still want to know how to wire in a 'conventional one'! I know it can be done! Link to comment Share on other sites More sharing options...
horsefeathers Posted October 9, 2015 Share Posted October 9, 2015 For what it's worth, I put a cheap ebay "Tiny Tach" onto my 582, with the lead wrapped around the spark plug lead, and it has kept in step with the "conventional" wired in hour meter for over 110 hours. Could never get the tacho to display the correct values however. Link to comment Share on other sites More sharing options...
