Adding an hour meter

There's no hour meter in my instrument panel. We track engine start and stop times and every few months go through them all and add up all the elapsed hours for maintenance but its a process that we could avoid.

Any recommendations on hour meters? What is the best place to wire it in? i.e. you can turn the ignition off and the engine will still run so that might not be the best place to connect the meter because you would miss running time.

In some cases you can fry the alternator by turning off the key while the engine is running. Recommended to wire it into the ignition.

Rockter will become famous soon enough
An engine hour meter is so rarely viewed, that it does not have to be on the instrument panel. I have one on an engine room bulkhead. An hour meter needs only to take its nominal 12 V positive supply off the ignition switch. All it needs then is an earth return to anywhere on the negative bus. Run the negative right to the battery negative terminal if you want.

Just splice a connection onto the positive side of the ignition switch, and route it to the hour meter, then an earth to the battery negative.

Hour meter is so p.c.. Didn't everyone call them "Hobbs meter" after the company that started or dominated it all?
