Nancy,
First off congratulations on your trouble shooting skills. There are only two things that will cause the symptoms you described (assuming the wiring wasn’t changed during the battery replacement). The 50AMP 12V breaker or the use/store relay.
The photos show the battery box location on my 2017 Compass 23TR. There is a yellow reset lever on mine. Difficult to see for sure. The use/store relay(Intellitec 01-00055-002) is under the furnace. Could have been a dirty relay contact that just started working again.
I’m dreading the time when all these hidden components start to fail.
Hugh
