Hey all! I'm trying to trouble shoot a battery issue with our 2018 4 wheel swift camper and wanted some expert advice. We have a solar setup and its been outside under the sun when we're not using the camper. I went to get the camper setup for some winter camping and when I turned on the furnace the fan came on, but the igniter didn't start. When I cranked up my truck and turned on the furnace again the igniter came on and the furnace warmed up. When the truck is running the furnace works. I can turn the truck off for 10-15min and it will continue to heat, but after 15min the igniter stops working and I have to start the truck again.
Any thoughts on what the issue is? I think my battery might be slowly dying, but I don't a way to check it.
Also, if I'm not using the camper should I take the batter out and keep it charged with a battery charger?
One last thing, should I get a volt meter to test the battery charge?
