Steps I took to upgrade the stock WFCO 8955 converter / battery charger in my RV to a better one: the Progressive Dynamics 4655.
The WFCO is famous for almost never switching into bulk mode (fast charging mode) no matter how low of a charge the batteries have. Because of this limitation, it’s impractical to dry camp – unless one plans on having to run their generator all day and night.
I haven’t gotten the new PD4655 to output 55 amps to the batteries just yet, but it’s already preforming MUCH better than the WFCO. I’m certain that once I upgrade the battery cable gauge from AWG #6 to AWG #3, I’ll get an even faster battery charge – in a matter of a few hours instead of 12+ hours. Even without upgrading the wiring, the PD4655 is already charging the batteries much faster.
NOTE: Tech support gave me instructions for fixing the problem with the green status LED not working. It turns out that the conductors in the 4-pin connector were in connected (at the factory) in the wrong sequence. I’ve posted the simple fix here: http://public.fotki.com/kevinkey/misc/
