We have a inverter charger 2000 12 VOLT that we can't figure out issues and are desperately seeking help in the Florida Panhandle (Pensacola). We have contacted dealers around Florida unable to assist. We purchached a 3000 to replace but are unsure how to install on our own. Basically looking for someone who knows what they are doing and able to fix current issues with the 2000 unit or install our newly purchased 3000. Please help. Thank you very much.
