WFCO’s new WF-8500 Series power center is the latest example of WFCO’s leadership in the development of new power center features and flexibility. The 8500 Series is brand new and should start appearing in RVs this year. It’s well worth getting to know this exceptional new product.

The 8500’s cooling system requires zero clearance for ventilation, and it has an exceptionally small footprint, thus increasing useable space for RV manufacturers to install other amenities.

For easy DC installation, a choice of three electrical connection modes are offered, matching those favored by RV manufacturers or dealers — either screw terminals, Quick Connect flag terminals, or wire pigtails. An exceptional range of 13 DC circuits, three of which are rated 30 amps, enables manufacturers to install more circuits for greater design flexibility.

LED light indicators that glow in a three-color code system provide instant information to technicians and owners about dead circuits, reverse battery polarity and bulk mode operation. LED lights also serve to indicate whether incoming AC voltage is low, normal or high, and each of the 13 DC fuse circuits contain a red LED light to indicate a blown fuse.

These and other 8500 Series highlights are raising the bar in power products for RV manufacturers, dealers and consumers. For full details click hereBIG_IDEAS_GRAPHIC_2

Typically when an RV service center discovers that a customer needs a new converter, the center will try to replace it with the same model from the same company. But why not guide your customer to a better product that can also enhance the dealership’s revenue?

Bat_Guard_ConvrtrsThe WFCO cross-reference guide provides an easy check of what corresponding WFCO products are available to replace the old converter or power center. This gives you an opportunity to move your customer into a WFCO product that excels in durability and functionality, and provides benefits not available in the converter being replaced.

One example of this is that many older converters use a one-stage charging system that does not have a trickle-charging capability. With all WFCO units, the three-stage charging system does have a standard trickle (float) charge function to keep the battery topped up when not in use.

The main point is that you can suggest a better replacement to benefit the customer, making their RV experience easier and more enjoyable, while also providing your dealership with a revenue enhancing opportunity.

WFCO Electronics now provides step-by-step, online troubleshooting guides for its different series of power centers and deck mount converters.

The handy one-page charts for each of five series lay out in graphic form a sequence of yes-and-no questions for technicians to answer about the problem. Depending upon the answer, technicians are guided either to a solution or to another yes-and-no question to further analyze the situation. This process continues until a solution is found.

These guides break down the problem analysis into a clear, logical progressionTroubleshooting_Chart_Pages of steps to help the technician quickly find and remedy the problem. This is another example of the support tools we’ve been developing for aftermarket sales and service of our products. The current guides cover the WF-8500 Series, WF-8700 Series, WF-8900 Series, WF-9800 Series and WF-9900 Series.

The troubleshooting guides may be found in the “Dealer Toolbox” under the “Support” tab on the WFCO website. Check back from time to time, as more guides will continue to be added.

Three ways to install right21. Have the right tools ready

If you have everything you will regularly need on hand for the installation of a WFCO product when you start the job, it will go faster and smoother. Here´s what you should have:

  • Multimeter
  • Screwdrivers, Phillips and flathead
  • Allen wrenches (hex keys); a 7/16 Allen wrench needed for WFCO products
  • Wire stripper
  • Torque wrench and/or screwdriver

Key note: Most people don’t have a torque wrench lying around, but it´s important to be able to measure the torque when tightening the electrical connections. Over torque can be as bad as under torque. Click here for a handy torque chart.


2. Strip the right amount of insulation from all wires.

The right amount will depend on the size and type of lugs used on the converter/distribution panel. Stripping too much insulation can create opportunity for a short circuit. If you don’t strip enough and push the wire into the lug too far, the lug might tighten on the insulation instead of the wire core, so no electric connection is made.


3. Do it right the first time …

Take time to think the job through. Even slow down a little to make sure you get everything right the first time. That is better than losing more time in redoing something. Here are some tips on ˝getting it right.˝

  • If the pigtail on the Black power lead for the converter is not used, be sure to keep it capped.
  • Make sure there are no frayed wires that could short to surrounding terminals.
  • Properly torque the screws on the lugs and bus bars.
  • Make sure battery connections are the correct polarity: plus to plus and negative to negative.
  • The fuse and AC circuit breaker size needs to match wire size, not the current draw on that particular circuit.
  • Dual circuit breakers can be used if not enough AC circuits are available when using single breakers.
  • If mounting a 9800 Series converter in a vertical position, be sure to mount it with the intake fan pointing down.
  • When installing a Power Center, do not mount it behind a door or in any way that will block the front panel air vents.

Three stage charging protects batteries.

WFCO’s automatic three-stage converter handles every charging need for the RV while extending the battery’s life. In fact, well-maintained batteries should never need more than WFCO’s two-stage (Normal and Trickle) charging modes. Our Fast Charge third stage (Bulk) is for the rare times a battery needs extra-power charging.

The WFCO Normal (Absorption) Mode alone is a powerhouse, capable of charging a fully-discharged battery in under three hours at 13.6 volts. When the RV is being used, the battery is kept readily charged in Normal Mode.

However, if the converter detects no significant variation in current draw for approximately 44 continuous hours, our Trickle (Float) Mode automatically kicks in and brings the battery back to full charge. Maintaining full charging in this manner helps prevent stratification of the battery’s fluids, which can reduce the battery’s charge and longevity.

For those cases when the battery charge drops significantly due to prolonged disuse, poor maintenance, or by significantly heavy system overloads, our 14.4 volt Fast Charge (Bulk) Mode kicks in. Our Fast Charge provides a maximum four-hour charge in order to prevent battery damage. This maximum time feature has been implemented to protect and extend the life of the battery.

The problem with overcharging a battery is that it tends to convert the water molecules into oxygen and hydrogen gasses, which can deplete the water and leave a strong acid solution, possibly damaging the battery. WFCO’s smart engineering makes Normal and Trickle the only charging modes the RV battery should ever require when it’s properly maintained.

If you have questions about 3-stage charging or concerns about over charging, please contact the Power Pros, call: 1-877-294-8997 Ext. 1.
