12v Problems

Surveyor sv180t
WF Converter

On the way home from a trip, lost 12v power

Hooked up to shore power, no problems.

Battery tested good, putting out 13

Checked fuses, tripped breakers, still no power when not connected to shore.

No voltage reading at terminal where the battery wires come into the WC converter.

Next step?

Thank you for any advice before I have to haul it in to a repair shop

There is usually a fuse (sometimes a resettable type circuit breaker) between the battery and converter. You'll need to look along your frame rail to find it, if nobody else chimes in with a location.

X2 Make sure to check wires in that box for lose connections. Also, check wires at battery disconnect switch if equipped. My ground wire came out of the eyelet when I bumped the wires. Nice and tight now.

EDIT: I see your trailer model now in the opening post

Did you see anything that looked similar to this?

Test lite from pos term. to the frame to test the ground from the battery.If you don't have a test lite get one jumper cable connect to neg term. then connect the other end to the frame and check interior lights. The ground is the most common problem in 12 volt faults.

the resettable fuse that WMTire posted a pic of, is along the A-frame, not in the bottom of your trailer.

Problem solved, the first thing I should have checked. Rust/corrosion on the battery ground wire connection. I still never fund the inline fuse though
