1. Connect the positive Watt Meter (WM) source wire (red) to the DC positive wire coming from the bridge rectifier. 2. Connect the negative WM source wire (black) to the DC negative wire coming from the bridge rectifier. 3. Cover these connections with shrink tubing or electrical tape so that there is no possibility of an electrical short. A electrical short could destroy the Watt Meter. 4. Connect the negative WM load wire (black) to the DC negative terminal of the battery bank. 5. Connect the positive WM load wire (red) to the DC positive terminal of the battery bank. MAKE SURE YOU INSTALL A 50 OR 60 AMP FUSE IN THIS WIRE. THE FUSE SHOULD BE LOCATED IN BETWEEN THE WATT METER AND THE BATTERY. Do NOT connect this DC positive wire to the positive terminal of the battery bank until the fuse has been installed.
