I have a 2003 Magnetec 6345 converter inour RV. I measured around 6 volts of AC voltage riding on the 12.8 DC voltage in the trailer. Is there a cheap, easy way to add filter caps to this converter, or would it be better to just replace it all together?

I'd suggest to replace it all-together. Most of those Magnetek converters were a single stage operation so will boil out a battery if not watched closely. Also, if you have 6VAC riding on the DC output, chances are that the converter is now failing or will fairly soon.

Please clarify if you are talking about something else besides the design of the 6300 where it has the split DC output, part of which needs the battery connected to act as the filter for DC going to sensitive items like the monitor panel.That 6300 filtering by the battery is normal so not a problem. (The 7300 is the newer technology that means converters no longer need a battery to filter their DC)If it is a different filtering issue from that normal 6300 one, somebody else will have to help here.

It probably is pulsed DC and not AC. Impossible to tell the difference with most meters. But the overwhelming opinion is that the Magnetec should be changed out for a 3 stage (at least).

I often state that if you have a Magnetek 6300 series EVEN IF IT IS BRAND NEW and just installed .... You should upgradeI recomment the Progressive Dynamics 4600 series, I think they do make a 4645, from Best Converters (or best converter, one is an audio store, the other RV store) you need to add one jumper wire.The Magnetek 6300 is a feroresonnant converter, no voltage regulation to speak of, it is widly known as a battery killer and rellly needs an upgrade. It also does not work withotu a battery.The lights, water pump and loads of that type do not mind unfiltered DC, radios and thigns that need FILTERED DC hook to the battery side of the converter and the Battery acts as a filter.... So you do not need a filter, Just a battery, and you will need a new battery often with that convwerter.So Upgrade. 2 batteries = a Progressive Dynamics 4600 and change, lots of change.
