2019 ARIA Inverter/Charger issue
Thanks to all of you that replied to my post regarding what I thought was an Inverter/Charger issue as the information for that device was not being displayed on my Firefly panel.
It was suggested by several folks as well as Thor Customer Support to reset the Firefly Power Management Module (PMM).
The procedure as outlined in the Firefly manual for my coach on line (page 27) was to power cycle the PMM by turning off the House battery disconnect switch and then removing the +12 volt power lug from the PMM.
Wait ten seconds, reconnect the power lug and turn on the disconnect switch.
This indeed reset the Firefly system and I can now see all the relevant/pertinent information as before the low voltage battery issue that required a jump start earlier this week.
In addition, after reviewing the Magnum inverter docs on line at Thor for my coach I was able to easily locate the power switch and status LED indicator for my future reference.
Again, thanks to all of you for your suggestions!
