Strange symptoms. Not sure what do do next.
Background: camping last weekend, always on shore power.
- Put TT in storage Monday. Inadvertently left a light on inside (2 12V bulbs). Got it out the following Friday, and noticed light was on -- quite dim. Turned it off, of course.
- Connected to shore power. Thought battery was charging (power distribution fan cycled on for a bit).
- Disconnected from shore power. DC bus dead -- no lights, level monitor out, etc.
- Removed batteries (2x6V in series) and charged them using external charger. They seemed to take the charge OK.
- Reinstalled batteries. DC bus still dead.
- Examined power distribution center (WFCO WF-890). All circuit breakers good.
- Checked all fuses visually, including reverse-polarity fuses and the unlabeled 30ADC fuse in position 11. All looked good.
- Checked battery with voltmeter: each at 6V individually, total at 12V.
We leave on a long trip in two days; planning only to stop in places with shore power. I intend to disconnect the batteries (they're not doing any good) for now.
Does anyone have any ideas of what to do next? Thanks much in advance.
