I was getting ready to go to camp driveway Saturday night when i realized i had no battery power. although we had been out for a week just a week ago, i thought that the battery must be completely dead. we stayed the night with shore power attached then i checked again and still no battery power. that put me into troubleshooting mode (what i do for a living) and soon found that the battery was fully charged and i had a blown fuse on the converter. (the one right above the reverse polarity fuse). i can not find a suitable wiring diagram to tell me what this fuse is for and whoever marked it at the factory,, well their penmanship could not be deciphered. i am assuming it is the output from the battery charge component of the converter. its the sole 20amp fuse just above the 40 amp which is not blown. wfco (the manufacturer of the unit) did not offer much on their site either. it is interesting that removing this fuse will essentially isolate the battery from the converter (winterizing) . i guess i was wondering if everyone had this "chicken scratch" on such important labels and if anyone else had this fuse blow for no reason too. we camped in a campground that warned of brown outs and the umbilical came loose from the truck once while pulling that could have done this but i would not think either really would have caused a fuse to blow.

thanks julie, that makes sence that it would be the battery charger/ battery input. i just dont understand why i would have had an overcurrent condition there. oh well, i will replace the fuse and watch and wait. thanks.

I had this exact experience the day I got home with my new 14RB. I was under the (mistaken) impression that the converter panel would have a red light indicator next to a blown fuse, and not seeing one, I discounted that as a cause. After trying the troubleshooting over the phone offered by my dealer's service tech to no avail, they told me to bring the trailer in. Turned out it was a blown 20-amp fuse. I bought a box of replacements, ensuring that it will never blow again.

I had a problem with the same battery fuse, but mine kept blowing when I tried to replace it, even with a different battery. The dealer said the converter was faulty and put in a new one. WFCO, the makers of the converter, will not honor their warranty because they say the battery must have been discharged too far, which is below 12.3 to 12.5 Vdc. If I were you, I would keep a careful record of the situations under which that fuse blows and discuss this with your dealer. As far as I can tell, 12.5 V is a 90% charge. It seems to me that a weekend of boondocking will invalidate the warranty on the converter.
The fact that a WFCO converter will not handle more than a 10% discharge is news to me. Since you had trouble with the same fuse, I thought you might find this interesting as well.
Hope things work out for you and your converter.

I've run my batteries much lower with no problems. I have read instances on other forums where batteries have been drained completely and WFCO converters have charged them up again with no problem. WFCO ( World Friendship Company) is an offshore supplier. It may be its company policy to deny responsibility. It seems to me if there was a symptom, and the symptom disappeared after the suspect unit was replaced, the replaced unit was faulty (as long as there were no outside influences, short circuits, polarity issues etc).

Yes, I've run the battery down much further myself, with no previous problems. As you point out, if replacing the converter fixed the problem, which seems to be true after a dozen nights of use, then the converter was the problem. My "conversation" with WFCO is ongoing and the dealer is talking to them on my behalf. I will just have to wait and see.
Our 19BH is the first trailer we have owned and I read a lot on the internet before we bought it. I saw many dismal tales of problems with early failures and poor warranty performance. KZ has a good reputation, but that does not necessarily extend to all their component suppliers. At least our dealer is working with us.
