Installed PD-4655

I installed the PD-4655 converter/charger today. There were two surprises.

The first is that the unit in my was 2009 25FB was not a Parallax but was a WFCO. I was surprised because there was no documents or stickers on the panel cover indicating the original unit had been changed. I never heard of WFCO so I don't know if it is a three stage charger or not. But Since I had everything torn apart I just went ahead and installed the new PD-4655.

And the second surprise, it seems as though everything is working as it should. I had a little difficulty getting the holes to line up and had to do some filing on the case to get the screws to start. It was difficult lying on the floor doing the work but with patience the job is done!

Does the WFCO have any value? Just curious.

Thanks for all the recommendations and input from forum members which gave a complete novice on electrical projects (me of course) the confidence to get this done!

I had the same issues getting the holes to line up when I installed my PD unit. I used a roto zip tool to enlarge them a bit so I could get the screws started.

My biggest surprise was how easy the swap went. Watched a couple of YouTube videos and jumped right in.

I believe the WFCO is made in China. The also manufactured the transfer switch in my 28' 2012 Intl CCD. I think just about everyone with the WFCO transfer switch had to have them replaced.

WFCO= World Friendship COmpany. They have been around for a while but still Chinese cheap components that don't last. They were a 3-stage unit though.

You are much better with the PD.

You guys might want to follow the thread reporting possible noise problems with a batch of the 4655's:

http://www.airforums.com/forums/f37/...se-151312.html

Lew have you heard anything about this issue? We are considering the same PD4655 upgrade.

Thanks,

Peter

I believe that issue was fixed some time ago. I have had no problems with my PD.

The reason I chose this one was, 1) because it was highly recommended by members of the forum whose opinion I have come to trust and, 2) it is a retrofit for the Parallax unit and fits into the same opening without having to modify the cabinet in which it is housed!

Perhaps that is somewhat helpful!

And don't forget that all Progressive Dynamics components are designed, manufactured and serviced in Michigan (that's in the USA!) and all of their components are of high quality from a company that stands behind them.

What other reasons do you really need??

I choose for the same reasons as listed by Hans and Lew. Very important was direct drop in replacement. After watching the available YouTube videos a dozen times it was almost plug and play.

So is it (PD 4655) a direct replacement for my Parallax 5355 in my 2016 FC28?

There is a Progressive Dynamics model that replaces a WFCO and at least one model Parallax.

You should contact Randy at sales@bestconverter.com. He would definitely know for sure.
