Loss of converter charge after using a coffemaker

I have no idea whether it's related but this morning in the primitive area we're staying I turned on my generator and used a drip coffeemaker. It was probably left on for an hour heating the pot. When I turned off my generator I lost all 12V throughout. Turning the generator back on I see the converter is putting out 14.6 volts but the batteries aren't getting that charge- instead they've dropped down to 11.5 volts which I presume explains why I have no 12V power. Is there anything in between the converter and the house batteries that I should be checking- it seems to me that should be an uninterrupted connection?

Thanks for any suggestions-

  • Find the battery pos cable...find the in-line fuse or DC circuit breaker on that pos cable (usually close to battery). It has blown or tripped (DC circuit breaker is a small box with 2 studs---most are auto resetting/some have a very small tab on side that has to be pushed to reset)

    Until you find/fix that 'protective device' NO DC charge from converter to battery

    I'm surprised to hear anyone running a Generator to heat up the high wattage type coffee maker for hours on end to keep coffee hot.

    Our coffee pot is only on 120VAC for about 5 minutes to brew up a 10-cup pot of hot coffee.

    We use the Cuisinart DGB600B which grinds and brews fresh coffee beans and pours up into a 10-cup thermos carafe.


    We do this each morning when we are using our 2KW Generator to power up our on-board Converter/charger unit to re-charge our battery bank.

    Might want to look into something like this to keep from having to heat up the coffee pot for hours on end... We always have hot coffee all day long and can brew up another pot in just five minutes...

    It's a nice thought but my wife and I don't even drink coffee but we put a little station up outside at our outdoor entertainment center outlet to let those in tents waking up through the morning have a place to grab a cup. I don't think we'll bother doing that in the future!

    There will likely be a breaker on your inverter. Sometimes more than one. About the size of a pencil eraser. They may not pop out, you can manually pull and push them to reset.

    Let us know

    We switched to the pod system and brewer which don't use a pot! One less thing for me, errr the DW to wash :B Little more expensive per cup but it seems to work great while camping.

    I replaced the converter with a Best Power Boondocker. It has two fuses, both of which check out fine. More important the unit is putting out 14;6 volts to the house batteries, which is exactly what it is designed to do unless the battery voltage climbs up into the high 12s.

    I did check to see as another poster suggested whether there was some breaker in the battery area under my inside steps, but the battery leads go up under the coach and I don't see where they then hook to the converter output lines. That's where I'm presuming the problem is since the batteries show only just over 11 volts in charge yet the converter is putting 14.6 volts to the line headed to the batteries.

    Mine pops when we inadvertently turn on 2 electric heaters at once.
