What does the solenoid power and what is it's purpose like battery disconnect, etc. I'm thinking it's always drawing power and perhaps should be a latching relay.
A DC clampon ammeter will go a long ways towards finding this and future electrical problems.
These tools are invaluable for the DYI RVer, especially for determing battery and AC loads. The clampon ammeter measures AC volts/amps, DC volts/amps, resistance, frequency (useful for checking a gen) and temperature. The accuracy is more than adequate for RV usage. The line splitter allows for easy measurement of AC amps for any plug in appliance. The female plug is on the bottom and the 2 loops allow for measuring 1x and 10x amps (useful for measuring small AC loads). About $75 for the pair. Check that any clampon meter you purchase can measure DC amps as they are less common than ones that measure only AC amps.
