Battery charging from TV not from shore power
Hello all. Noticed my battery was a little low when I picked up my trailer Friday to camp this weekend. I figured it would easily get charged with 2 nights if shore power. As I was breaking camp today last step was hitching up, electric hitch would not work. Battery meter inside camper said 1/3??? Been plugged in for 36 hours an no change??? I plugged the trailer back in to shore hitch worked fine, deities to TV and hitch worked fine. After driving home 45 min-1 hour battery now reads 2/3 full an hitch would work with battery.
Before I drag my camper back to dealer and wait a week or two for them to fix, and then tell me all you had to do was....<insert an answer here for me>.
Other info all fuses and breaker are NOT tripped/blown from what I can tell. All systems, lights, appliances work fine. Lights worked under battery power when the hitch did not so battery power is getting into the trailer
