Hi
when adding the starter battery the voltage was shown right
but than a little later, voltage dropped in shunt , but not in real, I checked with meter.
see trend data. any idea?
there is a drop in starter voltage without any reason
Actuall voltage of starter battery is still 25.2 but shunt showing 23.7
Check the connections especially any crimp you may have made and the terminal where the sense wire connects into the Smartshunt. Also check the fuse, sometimes these can be loose in the holder.
nothing changed, I did not touch it, and voltage jumped as shown in trend diagramm
I measured voltage on cable , and it is showing the correct voltage, but shunt not
yes
I am very astonished as I did not touch anything and the starter battery voltage just doubled
