36 24 Bad ground connections are a problem. Typically, the method they used for grounding the 12 VDC grounds is a big wire nut or a scotch lock, which can and will work loose from road travel. It is recommended that a ground bus bar is used for the 12 VDC ground. Grounding issues cause numerous bad connections throughout the 12 VDC circuits. Most charging issues are cured when a correct/good connection has been made on the 12 VDC ground side. Cleaning and maintaining the battery connections is also a very good practice. Continually tripping circuit breakers or blowing fuses. Take the time to collect load information on the circuits and fuse them accordingly to the connected loads. Having too many circuits on one branch may cause an overload situation that could trip the breaker or blow the fuse. Be mindful of start-up currents for motors and some big appliances as they draw large amounts of power until they enter the run mode. Also, check to make sure fuses are seated properly into the terminals. A loose fuse can cause it to blow or provide intermittent operation on that circuit. Over the years, our team of Power Pros™ have been working hand-in-hand with manufacturer production lines to ensure WFCO products are installed properly and utilized to their fullest potential. Our goal is to help make sure our products are installed correctly to minimize the potential for problems down the road. We are often asked about common missteps to look out for, and how to best resolve them. Below, we address five possible installation issues and the steps to solve them. Most involve fairly simple solutions that, if implemented, can prevent warranty claims and other complications in the future. AC and DC wires on converters are not torqued to the proper torque specification. Under torqued wire connections, both on the AC and DC sides, can cause heat build-up and reduced power transfer. Make sure all connections are torqued to spec if a torque wrench is available or, if not, are very snug without over torquing. The converter is mounted in a location with no ventilation. All converters are equipped with a fan to circulate cooler air across the internal components. If no fresh air ventilation is provided for the converter, it could overheat and shut down. Make sure the fan has access to fresh incoming air so the converter is properly ventilated. The battery is not charging properly. This could be caused by using the incorrect wire size needed for the distance from the battery to the converter. Long distances between the battery and the converter cause a voltage drop in the wire which lowers the available power. Larger wire sizes help reduce the voltage drop. So, shorter wire runs between the battery and the converter, in conjunction with a larger wire size, are always a good way to help minimize the voltage drop. 1 2 3 4 5 Installation Tips from the Power Pros™ NEED MORE ASSISTANCE?
