Using shore power without battery hooked up
We often use our Surveyor when we go to our hobby farm for an overnight. I keep the battery disconnected and hooked to a Battery Tender when it is stored there. We have been hooking the trailer up to 110V when we are there but not connecting the battery. Do any of you have any information as to whether this is harmful to the converter? It would be trying to charge a battery that isn't there. My sense is that that is OK since there is no completed circuit. Any evidence to the contrary? Don't want to take out my converter for something stupid.
