All ActivityMost RecentMost LikesSolutionsM1512 Trace Inverter & ChargerI have a Airstream Diesel Cutter with a M1512 Inverter Charger. Have power to house battery from outside source but can't get the power from the batteries to the inside of coach. AC comes in but DC doesn't. Had plugged in to RV park's 50 amp. No problem until then. Thank you.
