Hi there,
I installed my new 712 charger a few weeks ago and all readings were in line with loads and charge as I tried different combinations.
This morning I went down and turned on my battery charger it read 20 Amps while the BM only ready about half of that (11 Amps). When I turned off the charger the BM was reading about -4 amps slowly working it's way down to 0 but never fully getting there.
All loads were off.
Could this be a calibration issue and why would the behavior change even after it was working properly before? Does cold temperature affect the performance? It was down to 0C last night for the first time this year.
Thanks!
Andy
