here are the symptoms. plugged into shore power everything works as it should, unplugged nothing on the 12v system works with exception of the slides. monitor says no power and not one 12 light ill turn on but the slides will go in and out, do not know for how long but it worked for 1 cycle of the min slide. took battery out and charged, still no light and monitor panel says no power. jumped the breaker in the battery compartment still nothing, did not want to take in for warranty work if it is something simple so please offer opinions.
