Hi all,
I had my electrical system all wired up and working properly with solar and my starter battery going to my MPPT DC-DC charger, then to my aux battery. A starter battery positive went to the MPPT DC-DC charger, and a starter battery negative went to the aux bat negative. Everything was working. The alternator would charge the aux bat while driving, solar would charge it when not driving (or above a certain threshold even when driving), and when the aux batt was full, solar would trickle charge the starter battery. All my voltage and current readouts appeared to be working fine.
I wanted to install a smart shunt on my aux battery to clean up and simplify the monitoring process on both my camper monitor and on the app, but once I moved the starter battery negative from the aux bat negative to the shunt, I stopped getting any charge or readings from or to the starter battery on the app or the monitor. The DC-DC charger also doesn't show anything happening with the alternator like it used to.
All of my negatives are running through the shunt, and the shunt is the only thing attached to the aux bat negative. The only thing I changed was to add the shunt between everything.
What gives?
