Trailer light drains battery waaay too quick
I got a new trailer, light-weight. Same as posted on scionlife.
Hooking up the trailer "tail light" circuit, through a 3 wire to 2 wire "converter" drains the
battery to near dead in about 5 minutes. But, there is no short in the trailer. I know this
because I hooked up the same circuit to a 12V powersupply & measured the current,
and its fine at 3.6A. A short would be a lot more.
If the additional 3.6A was exceeding the fuse rating of that circuit (10A I think) then the
fuse would blow, but it wouldnt kill the battery so quick.
A dead battery could be the culprit, but it shows 12.6V open circuit voltage, which acc.
to the manual, is fully charged. And I can run the head lights/radio for a long time, but
hook up the trailer, and bam, radio dies, battery light comes on, battery gets killed.
Anyone have any ideas?
