After putting in a set of new 6v batteries hooked in series my inverter started to hum or buzz. Anyone have an idea what would cause this? Batteries were hooked up exactly like the old set. Thank you
Hooking up 6VDC batteries just like before sometimes doesn't work. You need to find the + and - markings on the battery case and wire those up the same as before... Sometimes the newer batteries have the terminals in different locations even with the same brand of batteries...
