How to clean up 12V power for electronics?
Hi, I have a very old (1990) Winnebago Warrior RV. The converter makes "dirty" power and as a result the TV, when we are plugged into shore power, goes haywire. Runs fine on battery power. To...

Unless you are disconnecting the batteries when you are on shore power, you are running off the batteries all the time you are on 12V. On shore power, your convertor comes on to charge the battery. It is possible your convertor is so noisy it causes issues with your electronics, but a battery is a pretty good filter to remove the noise so it would have to be fairly significant.
I'd be thinking that your convertor is bad.
Converters have 2 functions
*Maintain/charge batteries as needed
*Provide 12V DC Power
When connected to 120V AC Power the converter supplies the 12V DC System voltage demands and charges battery until battery is charges then 'charging' section goes into float mode .....
Disconnect the battery cable and RV will still have 12V DC Power from converter
(OLD converters needed battery in place as a 'load' but still provided the needed 12V DC -----modern/new converters do not even need a battery to function)
OP............
Replace that OLD 'OBSOLETE' B&W Model 6332 with a PD Unit
Instead of the 35A unit (in link) I would go with 45A at minimum
Amp rating is total DC load available......DC System and charging
New fuse board......all circuits are filtered with/without battery
Old fuse board....only 7-9 and only if battery installed
Magnetek/B&W etc direct replacment
