This section was designed to answer questions for RV owners as well as technicians and is divided into three categories which are: General, Electrical and Troubleshooting. The latter can be particularly helpful for technicians as step-bystep direction is offered toward a solution. Look for FAQs under the “Support” tab at wfcoelectronics.com. Know your FAQs — Electrical: What is the reverse polarity fuse? The reverse polarity fuse provides protection for the converter when a battery is used. If the battery was connected to the DC fuse board backwards, the Reverse Polarity fuse(s) would blow preventing catastrophic damage to the converter. — General: Does the converter need a battery to operate? No. The battery works in conjunction with the converter to supply DC power to the RV. A battery is typically only necessary if you do a lot of dry camping or have slideouts and/or a leveling system.

If the lights in the RV are flickering, that usually means that the converter is overloaded. 1. Remove some of the load by turning off 12V lights and appliances. 2. Turn off the converter for 10 seconds to allow the unit to discharge by either turning off the breaker or unplugging the unit. 3. Turn the converter back on. 4. Check your battery. It might be damaged or the water level may be low. 5. Check the output voltage of the converter. It should be at 13.6 VDC range. Keep in mind that your battery can pull up to 30A or more from the converter. Low temperatures also will have major effect on your battery’s performance. 25 TECH TIPS Tailored specifically to lithium-ion batteries, take advantage of our lithium chargers: WF-8950L2PEC WF-8950L2-REP WF-8950L2-MBA WF-9850L2 These chargers will replace energy back into the lithium-ion battery to 100%, while using multi-stage charging processes.
