Magnetek/Parallax to Ultra III

 
Below are photos of the Conversion.  Replaces 6300 or 7300 series B-W, Magnetek or Parallax.  Includes new fuse board.  Simple to install.  Call if you have questions.  It should only take about 30 minutes.
Look what might be lurking under your power center.  One of our customers sent this photo of the floor beneath his old converter.  Thanks for the heads up Ron.
 
Before attempting ANY electrical repair to your RV, it is important to remove all electrical power (AC and DC) and disconnect the battery cables. 
 
 
 

Remove all covers exposing the DC fuse board, AC breakers and lower converter section.  You may have up to 9 additional wires attached to the DC fuse Board.  You can remove them now and mark their position for installation on the new fuse board.  Make sure to transfer the properly rated fuse to the same position on the new fuse board.  You can reuse yours but if your unit has glass style fuses, you will need to purchase blade style for the new board. 

 
 
Remove the fuse board and the blue, red and white DC wires. 
 
 
 
Remove the plate to expose the wires to the breakers, neutral, and ground bars
 
 

Note:  We have only two circuit breakers installed for illustration purposes.  You will likely have several more and maybe even twin style breakers.  These do not need to be removed unless you are replacing them as well.  Locate the breaker that powers the lower converter by following the two wires up from the lower section.  Remove only the hot wire (Usually black) from the breaker and the neutral wire (Usually White) from the neutral bar.    

When reinstalling the AC wires from the new converter, there will be a third wire (Green) that will need to be connected to the ground bar.
 
 
Remove the lower converter section screws and slide the unit out. 
 
 
 
Reverse the process with the new unit.
 
 
 
 

Note the new fuse board only needs two DC cables from the new converter.  The red cable connects to the top of the fuse board where the old blue cable was attached.  The entire fuse board is powered from this red cable. 

Attach the white cable to one of the lower “Neg” lugs.

 
 
Install appropriately rated fuses to the board.  Install accessory wires to the corresponding fuse positions.
 
 
Install incoming battery cables to the “Pos” and “Neg” positions on the fuse board.  Note, this is a good time to determine if you need to replace your battery to converter cables.  They need to be properly rated and we recommend a minimum of 8 AWG however 6 AWG or larger would be better.  Most cables are at least 8 AWG but you need to make sure.  This is important for safety and good charging performance.  Long runs to the battery with underrated cable will cause a voltage drop and reduce the charging performance of your new converter.
