Yeah absolutely check fuses & breakers after checking voltage with a multimeter if you have one. Also make sure cables are tight. I ran my 25bh after 2 days of shore power & one night in Walmart, just tapping a led light once in awhile, & had a full charge. I took the battery out & keep it on a trickle charger when not in use. The 2017 J feather 25BH I have now has a red positive & black negative battery wire setup , make sure they are correct., GL with the battery.
