Electrical Help

I relocated my battery and reconnected it and may have accidentally reversed the polarity.  Nothing was active except the gas detector, which is always on.  I thought black was neg and white was positve.  It appears I was wrong?  I do not feel very smart right now.  Well when I connected what I thought was ground there were some small sparks and then nothing.  Now I have no DC power.  When I plug it into my house it is fine.  All the fuses in the inverter appear to be fine.  Are there any other Fuses in the DC circuit that I may have popped or could it be a bigger issue.  

Thanks for any help.

There is another fuse in the back of some converters. If anything blew, it was probably that.

I can't believe that they would build something like that and not add a 10 cent capacitor in the ground circuit to prevent this sort of thing. It may be that they just consider it a source of income (new convertor sales) if someone makes that inevitable error.

Some converters have an internal fuse (IIRC 7 amp Buss) that is designed to blow when the polarity is reversed. You will have to open the converter back to find it. Usually with a flashlight, standing on your head...LOL

But I would also "Check" the fuses with a multimeter. I wish I had a dollar for every hour I wasted over the years chasing electrical problems that turned out to be a fuse that "looked good".

 I said the same thing when we picked up our new camper a month ago. Person helping us go through it went and got the battery and started putting the black on th positive and I stopped him and ? him. He said yep black is positive , he came from car stereo place and screwed up a few in the beginning. He learned fast.

Thanks for the feedback.  I am a little embarrassed with this one.  If I would have actually ready the inverter manual and the fuse lable on the the inverter I would have seen the "battery fuse".  Funny thing is that I looked at all the 15amp fuses thinking it would be one of them and did not look at the 30amp.  As it turns out the "battery fuse" is the 30amp one and it was toast.  $2 later all is well and we are back in business.  FYI I have the 6700 inverter which I am assuming was or still is the standard inverter for the Fleetwood PUs.  Yes black is pos and white is neg.  Live and learn.

It's actually not an inverter. It is a Converter.

The converter turns 110v AC current into 12v DC so that your 12v lights, water pump etc will work when the camper is plugged into 110v hook-ups at the campground.

An inverter is a separate piece of equipment that you can by to turn 12v DC current into 110v AC so that you can run your household appliances from you campers battery.
