Hello all, new to the rvforum site, happy to join you all!! I am hoping to receive some guidance with my 2003 26' Thor Wanderer Wide Lite. I have owned my trailer for almost 5 years now and up to this point, the 12 volt DC system has worked properly. This year when I was performing spring maintenance and functional checks, i noticed that the 12 volt DC system was not working at all. I was running 2, 4 year old 12 volt "deep cycle" batteries. The batteries wouldn't hold a charge and I confirmed they needed to be replaced with my local provider. I upgraded to 2, 6 volt deep cycle batteries and am running them in series to achieve the proper voltage. After upgrading the batteries, to my surprise, the 12 volt DC system is still not working. My converter/charger system is a Parallax 6435. 110 Volt AC and all 12 Volt functions work fine when connected to shore power and generator. I am hoping someone can help me solve this issue ;D. I recently found the Parallax manual and am reviewing so I can test further but i'm hoping someone can help me avoid a lot of time and aggravation.
Here is what I have checked/found thus far:
I'm not sure if there are other fuses in this trailer that need to be checked, I haven't been able to locate any others. I did find what looks like a Type 1 circuit breaker attached to the frame, one of my 2 positive wires from the battery is connected to one end; and a positive wire goes from the other end to my converter (i believe). This breaker and the wire connectors look very corroded, not sure if that could be the issue.
Any suggestions or recommendations? Any guidance would be greatly appreciated!! )
Here is what I have checked/found thus far:
- Confirmed that I have 12+ volts at the battery terminals
- Checked all 15 amp fuses in the DC distribution panel, they all were good, not blown
- Checked 25 amp fuse in utility panel on outside of trailer, not blown
- Checked 5 amp fuse in utility panel on outside of trailer, not blown
- Checked 10 amp fuse connected to water pump, not blown
- Confirmed that I do not have any power at the DC side of the distribution panel
- Replaced all of the connectors (2 +, 2 -, 1 series wire) that attach to the batteries to ensure good connection
