Ah, now that makes a huge difference! That is one of the things I really like about my surge protector. It tells me if there is no ground on the pole, so I know when my trailer has lost the ground connection. Many do not realize how important that stupid little wire is. Sounds like you should be OK now.
The trailer dealer I normally deal with doesn't deal with new trailers. A lot of what he sells are on consignment. He goes over EVERYTHING with a fine tooth comb and guarantees everything to work when I pull it off his lot. Once I had a problem I found two months later and he took care of it for me. That is hard to beat.
If you buy from a private individual you need to be very carefull and know what to look for. Did you put the "old" battery back in? Might as well and have two hooked up to the trailer. It can't hurt unless you can't handle the extra 60 pounds of weight.
