So we hooked up a battery (only have one right now) and now observe the following:
1. When mode is LP the indicator lights appear green and steady. We can hear the gas through the outside vent area when cover is off. Sounds like a regular furnace. No odor detected.
2. When mode is Battery indicator lights are green and steady. We can hear the electronics under the bench seat.
3. However when mode is AC power the ! light blinks red and the AC indicator light blinks green.
4. All the lights in and outside of the trailer work with the AC power and no battery connected.
5. Fan, heater, and air conditioner all worked with AC power and no battery.
6. One plug in the slide out kitchen area does not work but all of the others do.
7. We haven't put water into the system yet so we don't yet know if the water pump or water heater work.
8. Stove and microwave both work.
If the indicator lights appear correct in LP mode should we assume it's operating and wait to see if it cools? The outside temp has warmed up now as well as the inside of the trailer.
Any ideas of why it is showing the ! blinking light when in the AC power mode with most of the other electric things working?
