Thanks for the info. If I understand you guys correctly, the water pump is only wired DC. That would explain why there is no power to it while I'm on city power as I do not have a battery installed yet. Does this mean that the water pump does not work on AC power? I probably sound clueless but I'm familiar with home AC wiring and auto
12v wiring but have no experience with RV's with dual systems. Since it will be a while before this trailer is on the road I wasn't ready to buy an RV battery yet. Maybe I can hook up my lawn mower battery to run some tests on the
12v system.
