I installed a BMV700, BT dongle and shunt a couple weeks ago in my camper and everything worked great. Monitor read fine, connected easily to iphone, all was good. I'm preparing to head south after the holidays so have left the camper powered up on shore power.
I just went in camper to check things out and the meter was blank. If I hit select it will scroll through readings quickly then go blank. Bluetooth dongle was reading an error light and would not reconnect.
Factory battery monitor in camper reads 100%. Unplugged shore power, no change. Checked battery wiring including fuse for BMV and all looks good. Did a reset of the meter (pressing setup and select for 3 seconds) still no luck...
Suggestions?
