It's time to upgrade my battery monitoring system. Two reasons:
1) My current system is annoying to use. I have to reach over and plug the voltmeter array in while I am driving. Not the safest...
2) One of the voltmeters on my current setup is dead, so it needs work anyway.
So what I have planned is one voltmeter for system voltage and one voltmeter for individual monitoring, both mounted in the dash panel. A six position, two pole rotary switch will be used to toggle between each pair of batteries for monitoring.
Here is the current proposed wiring schematic:
