(And here’s a link to help you find replacements – ed. According to the manufacturer, the new TempAssure system provides “multi-staged output coupled with temperature compensation.” I think this is not only an easier option, but a better one, as it has the temperature compensation feature which is only available with Parallax and Xantrex (TrueCharge2) to my knowledge. It is a direct replacement for the lower section of your existing unit.
#RV POWER CONVERTER REPLACEMENT UPGRADE#
If you determine that the unit has failed, the company has introduced an upgrade package called the TCRU which will upgrade the converter to a regulated 12 VDC power supply with temperature regulated battery charging. Locate brand name of your converter and use the pull-down menu to access “diagnostic” information – ed. ( This site contains a number of archived documents, including diagnostic flowcharts for several converters, including the Magnatek and BW Phillips lines. Parallax has a diagnostic flowchart which helps determine this. That said, if all the system is putting out is 12.1 VDC, then the lower section has most likely failed anyway. Not impossible, but should be done with care. Furthermore, modification of the Parallax power center would be required to run the new wiring in. However, it will require the installation of a new deck-mounted converter/charger with an AC receptacle, new appropriately sized wiring for the DC side, grounding, etc.
#RV POWER CONVERTER REPLACEMENT INSTALL#
The short answer is, yes, you can theoretically abandon the lower section of the Parallax system and install a deck-mounted unit. My question is: Can I replace the Parallax with a WFCO converter/charger 45 or 55 amp? Thanks. The noise stops when the converter is shut off, plus the house batteries are never above 12.1 volts.

The converter is a Parallax model 7345, which is causing excessive noise on the AM radio band.


I have a problem with my converter/charger on my 2006 Winnebago Sightseer. Here is a letter he received from a reader while he was serving as ’s technical editor. Chris Dougherty is a certified RV technician.
