Solutions? I found out its a TODD ENGINEERING 45amp model.
Not sure how you're connecting this - your battery charger shouldn't be hooked to the isolator, but it may be that we're each using different terms. On the DC side, it should have two fat wires going directly to the battery (positive and negative). On the AC side, it sounds like it has a regular three-prong plug. Try plugging something known to work into that same receptacle, to make sure there's power at the plug.
