It looks like you're new here. If you want to get involved, click one of these buttons! We were aIso told that since the DC power out of the power center was There was no cost to me as everything was repaired under warranty.
As an engineer, I have this driving compulsion to see how something works or why it broke down. So, I called WFCO manufacturer and talked to the production engineer giving him the following information. The engineer stated that I had a failure in the three stage switching power supply and both battery and power center needed replace. He also stated the three stage power center is designed with three modes of charging Absorption, Bulk and Float and can be energized all the time with battery connected as long as the battery is checked and watered if needed every weeks.
This is where the problem arises, I know electronic devices fail, especially new ones when put under a load. The manufacture assures me this is not typical but occasionally does happen. On the other hand I have no less than 3 technicians at the dealer telling me never to leave the shore power energized if a battery is connected for an extended time.
It is hard to dispute the information from the technicians as they work on these systems everyday. Has anyone experienced this problem? Not knowing who to believe, I installed a battery switch since the voltage drop in a lead acid battery is about 2 volts in a 6 month period when not being used or charged.
Thanks for all the comments. Since I was in the process of installing an internal surge protector, I also installed a multi battery switch and a circuit to support the Batter Minder. My next project will be designing a solar array using 2 semi-flexible bendable watt panels for use in the Southwest. Discussions Activity Best Of Howdy, Stranger! Sign In Register. Categories 9.

WFCO Ultra III Power Center (Model WF-8735P)
I guess instead of hooking into the shore power outlet while stored, I'd just use a battery tender hooked into household current directly to the battery bypassing the converter.
I have not heard of this problem. Have you tested your power source, too? Tabster Member Posts: I've had my CS plugged in continuously for 9 months, with the exception of a few weekend camping trips. No problems at all. I keep my fridge on so i don't have to bring butter etc into the house - or remember to pack it. ChanW Member Posts: 2, November edited November Ours is always plugged into shore power whenever we're not camping.
I've kept track of the battery water level, and had to add a few tablespoons once, in two plus years. A good three stage charger is designed to be connected all the time. I'd go with the manufacturer's knowledge of their product. And I'd question why the techs are giving you wrong information That's a good warning for us all, though.Your question may be answered by sellers, manufacturers, or customers who purchased this item, who are all part of the Amazon community.

A few days later I went out and flipped on a light and still nothing! I lifted the cables from the battery and it was indeed discharged but with both leads lifted and the V supplied to the converter there is still no 12V.
The converter is from World Friendship Co. This model has the v circuit breakers on the same panel face and is the WFP. In doing some testing I discovered that if I cycle the circuit breaker for the converter off, then on it will have 12v long enough to cause the interior lights to flash on, not when you first turn the breaker on, but for a couple of seconds when you turn it off!
I am wondering if anyone here has any experience working on one of these and if they know where I might find a schematic for one? I have some suspicions about what may be happening, but at this point they are only guesses. Thanks, John. I didn't have it but in looking at the testing, the picture of the fuse board isn't the same as I have so I'm going to have to figure out a few things, but it can't hurt.
Looks like that one came from and mine is so that may be the reason. I'll let you know if it helps any as I did save it just in case. Still looking for a tech manual as well. In doing some more searching on the internet, I found this troubleshooting guide, but it sure doesn't tell a person much! The page seems to be pointed at dealer techs and has several others, for what they are worth. You're welcome I bet you will figure her out and hopefully its fixable.
I even took a course in Vacuum Tubes is how long its been since I was at Purdue lol. I'm not going to insult you with the "minutiae" I'm quite sure you've already checked You've been around the block a few times.
To note If you're not getting readings on the outputs you'll need to test the center taps. I would call myself lucky on the WFCO The other route would be a drop in control module replacement.
Were all havin fun spending Kirks money yayyyyyyyyy lol Id guess he would have far more fun PLUS save the money if he fixes it himself. The catch is that the link lists direct replacements for the WFCO series and mine is an series.
It doesn't look to be a direct replacement. I did send them an inquiry to see if there is something for what I have now. Take a look at a progressive dynamics series conver. They have worked good for replacements and only seen maybe two go bad in my time as a rv tech. Now if you have time to fiddle with your unit it would be interesting as to what really is bad with it. I like my current charging algorithm for flooded lead acid which Bulk charges at When my inverter failed, it burned up my converter.
The invert was taken in for repair u dear warranty. I was going to replace the converter but realized that it had been turned off for several years as the inverter charged my batteries. I decided not to replace it and just let the inverter continue to charge them. Their "equalization" cycle is more of a "mini" version and not to be confused with a traditional equalization.
Under normal use, like John's, you may not always have a low enough SOC to trigger a bulk charge for any meaningul amount of time. The PD throws itself into a "mini" equalization of The theory with a bank under storage is that the regular "stir" will keep stagnant plates more active.Wfco Wiring Diagram — wiring diagram is a simplified within acceptable limits pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the knack and signal links amongst the devices.
A wiring diagram usually gives suggestion virtually the relative slope and deal of devices and terminals upon the devices, to support in building or servicing the device. A pictorial diagram would comport yourself more detail of the mammal appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections higher than mammal appearance. A wiring diagram is often used to troubleshoot problems and to create sure that all the links have been made and that everything is present.
Architectural wiring diagrams fake the approximate locations and interconnections of receptacles, lighting, and surviving electrical facilities in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be upon a common circuit. Wiring diagrams use satisfactory symbols for wiring devices, usually alternative from those used on schematic diagrams. The electrical symbols not single-handedly feign where something is to be installed, but in addition to what type of device is visceral installed.
For example, a surface ceiling well-ventilated is shown by one symbol, a recessed ceiling open has a rotate symbol, and a surface fluorescent well-ventilated has out of the ordinary symbol. Each type of switch has a oscillate tale and appropriately reach the various outlets.
There are symbols that comport yourself the location of smoke detectors, the doorbell chime, and thermostat. A set of wiring diagrams may be required by the electrical inspection authority to implement relationship of the house to the public electrical supply system. Wiring diagrams will as a consequence add together panel schedules for circuit breaker panelboards, and riser diagrams for special services such as blaze alarm or closed circuit television or new special services.

Amanda, United States The Natural Wonders of Iceland, July 2016 Our tour guides we awesome. The lady that did our city tour was well informed and kept the kids entertained.
After that tour, I was looking for street art whenever we walked somewhere. Our tour guide that we had for the golden city tour was well versed and loved her job. Throughout the whole experience, I never had a bad customer service experience and welcomed by all. We were a bit bummed that it snowed the second day, but that only last a little bit.
