Converter question

The converter wasn't working so I pulled it out of the pop up camper. It turn out that the fuse holder was loose so I fixed it.

Now it working but it outputting over 15V DC. Is that normal for this type of converter?

It's a B-W Manufacture Series 6400 / Model 6415 converter, I know it quite old but I only wanted to run the 12V DC lamps and refer in the pop up camper from a 120V AC.

I can see that the way the converter is hooked up that it not used to charge the battery.

I have no plan to use it to charge the battery. I will not have a battery installed on the pop up camper.

There a selector switch on the converter itself but I believe it to select between the converter or 12V DC battery to power your pop up camper.

  • Give Randy a call at best converter. I also believe that voltage at 15v is probably ok without battery. But, information is free and Randy will definitely point you in the right direction.

    I did look over some modern day converters at RV salvage place which are smaller in size and they wanted a hundred a piece for them.

    My issue is that I am not sure if I wanted to spend the money on this pop up camper and may get rid of it after using it this summer and go with travel trailer next year.

    Add a battery and watch the electrolyte level (add water as needed) and it will work fine.

    No regulation. Open lead voltage is about right without battery.
    This type will boil you batteries so you need to keep an eye on water level.
    I would think about spending money for a newer style converter. Talk with Randy at Best Converter for best converter for you.

    Older converters were designed to be operated when connected to a battery, they have poor voltage regulation and lots of voltage ripple.

    If you load the output without connecting it to a battery, chances are the output voltage will lower to an acceptable value, but the ripple voltage will increase too.

    The no battery issue may create problems with some electronic devices.


    Yes I agree with you on this but the way this converter was installed in the Starcraft pop up camper, it wasn't connected to charge a battery.

    Maybe previous owner tried to rewire it separating it from the battery.

    I wouldn't use it... Asking for problems...

    Smart Mode Converters the way to go. They will take care of your battery for you...
