The Van's electrical diagram installs a ammeter between the battery and the alternator. Thus, the gauge shows battery draw or charge.
For those with modern panels, EMS, configurable panels, etc. What do you measure and/or show ?
Some options I am considering are:
- measure the current between the battery and the alternator just as Van's describes
- measure the individual current loads for the battery and the alternator (and the backup battery if one exists) - this would require isolating the battery charging circuit(s)
- measure the current between the battery and the alternator but also measure the current load of the backup battery
- something else
I am already planning on monitoring voltage for each source.
