Hi,
I have an R-Vision Trail-lite 2002 with a Parallax 7355 converter.
My rig is currently on mains hookup but none of the 12v circuits are working.
Using a multimeter I have discovered the following:
Removing both 30amp polarity fuses and testing between the converter input to the fuse board (blue wire) and the negative connection gives 13.6 volt.
Testing across the battery connections at the converter fuse board gives 13.6 volt
Replacing the polarity fuses and testing from any of the 12v circuits positve (just below fuse) and the battery negative connection on the fuse board gives 13.6v.
NO 12v circuit works.
Now, despite having a reading across the battery connections on the converter fuse board of 13.6 volt, the actual reading at the battery is 9 volt. Now I know that this means that the battery is no good, I can't understand why I get the differnce in readings.
Also, and perhaps crucially, if I connect an external battery charger to the battery then the 12v circuits in the coach come on...
And in case it helps, with the polarity fuses removed, the reading at the fuse board across the battery connections is the same as at the batteries.
I am really confused as all the information I can find says that the Parallax should be powering the lights etc even if there is no battery, and I do read 13.6 volt at the 12v circuit fuse bu tget no power anywhere.
I really hope you can help as we are due to go away for a couple of weeks real soon.
