One Starting Battery For Two Engines? (About Hour Meter)

Question about Hour meter
If implemented V4.0 diagram, where should I connect the Hour meter gauges?

My alternator has three terminals (Battery out, Sense Field), internal regulator and GND. Currently, the hour meter gauges are connected to the output of each generator, or whatever it is, at the entrance of the 2IN/3OUT Diode Battery Isolator. Obviously each gauge is independent of each other, separated by the diodes Isolator. In diagram V4.0, acting ACR, put each alternator in parallel, so I cannot connect the gauge to the output of each generator, as it would mark false values of each engine. Example: if the port engine is off and the starboard engine is on, by acting the ACR, the port hour meter would be adding hours when the engine is off. where should I connect the Hour meter gauges?

P.S.: I have a made some changes for the ACR override signal, using relays instead than diodes

I just answered myself: With the oil pressure switch. Thanks anyway

One Starting Battery For Two Engines (My final solution)

Happy New Year to all,

This is the definitive design for my 3 battery/2Engines/2Genset main DC switchboard. I start to connect the panel and planning to finish in the middle of February. Then I will upload some pictures of the installation. The following pictures are in los resolution, but I have uploaded a PDF hi resolution file for each of them, that you can see it in the following forum: http://www.boatinghowto.com/f28/twi...teries-configuration-517/index3.html#post1220. Also, you can see some pictures of the construction of the panel on that topic.
