Power Converter Upgrade

[mjlaupp]

PD4600 1 of 2 - or - Installation is the Reverse of the Removal

I decided to upgrade the power converter in my 2004 3326. I did this in my 2003 2720SL using a 7345 converter upgrade kit. It improved the battery life and reduced radio noise. The latest incarnation of the Intelli-Power converter with Charge Wizard is a direct replacement for the Parallex converter installed in my TM. It provides three stage charging and desulfation to extend battery life.

In all fairness to PD, they do say that this should be done by a qualified electrician. I'm not a electrician however I do have many years of installation, maintenance and programming of industrial computer and control systems so I consider myself to be a qualified technician for this install.

PD4600 2 of 3 - or - Installation is NOT the Reverse of the Removal

I decided to upgrade the power converter in my 2004 3326. The included instructons (as modified) are reproduced below:

------------------------------------------------------------------------------------------------------------------------

Intelli-Power PD4600 Series Converter Replacemant: Modified

Power: (page 1)
Disconnect all power sources prior to removal of the old converter. Power sources may include, but are not limited to:
• 120VAC shoreline power (unplug shoreline power cords)
• Onboard generator (disconnect per manufacturer’s instructions)
• 12VDC battery power (disconnect negative terminal(s) from battery(ies) ) I pulled the battery fuse.

Removal: (page 2)
1. Disconnect all power sources as outlined on page (1) of this manual. OK
2. Remove front panel by removing (4) screws at bottom of panel. OK
3. Remove AC power section cover by removing (2) screws. OK
4. Disconnect the neutral (white) converter feed wire from distribution block, and hot (black) wire from AC fridge/converter breaker. Pull wires through the hole at the bottom left of the AC power section. OK
5. Remove the (2) DC power distribution board mounting screws. OK
6. Pull the DC board outward and remove the blue wire from the top of the board, and red and white wires from the BACK side of the board. Pull wires through the hole at the bottom right of the DC power section. OK
7a. Remove red wire (2 black #10 solid core wires) from the FRONT of the old DC board, and reconnect to the terminal labeled “BATT POS+” on the new DC board. These black wires are so stiff that reconnection can not be done at this time.
7b. Remove the white wire (3 white #10 solid core wires) from the FRONT of the old DC board, and reconnect to the terminal labeled “BATT NEG-“ on the new DC board. These white wires are so stiff that reconnection can not be done at this time.
7c. Transfer branch circuit wiring in this same fashion. 7 of the 9 branch circuit wires are too big to go into the barrier strip on the new DC board. The grommet for these wires pulled out of the box. I marked each of the wires, pulled them out of the box, reinstalled the grommet and re-pulled the wires.
8. Remove the (4) screws securing the old converter assembly to power center, and remove converter assembly. OK

Tools used to this point:

Common screwdriver(s)
Phillips screwdriver
Square head driver (on AC breaker)
Nut driver(s)
Side cutters

Additional tools used:
Allen wrench for batt connections on new DC board
Wire strippers
Wire terminal crimpers
Ink pen
Multimeter

Additional materials needed: (not included in upgrade kit)
Black #10 insulated automotive wire (battery wire extension)
Yellow (or white) #10 insulated automotive wire (battery wire exxtension)
1 - blue 18-14 awg butt splice connector (for AC power wire)
4 - yellow 12-10 awg butt splice connectors (for battery wires)
2 - red 22-18 awg spade lugs (for branch circuits #1 & #2)
7 - yellow 12-10 awg spade lugs (for branch circuits #3 through #9)

--------------------------------------------------------------------------------------------------------------------------

Ok, it's done! The converter is quieter, the charge wizard is blinking fast mode indicating normal mode charging, the 12v fans in the TM are quieter with the filtered DC and only time will tell about the battery life. I can now leave my TM plugged into shore power without fear of cooking the batteries. Now it's time for some LED bulb replacement.

Time investment: 8 hours.

DC output voltage: 13.96v

Pictures will follow.

Interesting specs I may consider this if mine gives any problems but it is too new to replace now.

Did it fit existing location without modification?
What was cost of this upgrade?
How about some pics.

Check out this thread on the same upgrade. There is some very interesting info in it:

Be sure to read each post as I progressed through the installation of this converter. It's a great converter but to get the total benefit of it, it needs to be mounted very close to the batteries or very large (battery cable type) wires must be installed between the converter and the battery.

This install was in a 3326King. This is one of the front slide out models with the batteries (2 6v golf cart batteries) located in the rear storage area. The distance from the charger to the batteries is no more than in your front converter installation. I'll have to evaluate this installation over the next few months and will provide updates as needed. I chose this upgrade because it was supposed to be plug and play. I had no charging problems with the 7345 upgrade in my 2003 2720SL. It was a 45 amp charger and had the same distance to the 2 golf cart batteries.

AHHHHH!! I didn't realize that you had a slide.......that changes everything...

Assuming the batteries are under 10' from the converter, you should get acceptable voltage. The problem is with those of us that have that long distance between the batteries and converter........good thing lots of people read these posts.....maybe my experience with this upgrade will help someone..
