Overload Protection
The power converter has separate protection of 9 amps per output channel
to trailer lights on the marker lights and left / right brake lights and turn signals.
For example, if the marker lights draw excessive current, the brake lights and turn
signals will continue to function normally. After power is removed (lights turned off)
for several minutes, the power converter will reset itself.
The trailer tow battery feed and rear outlets share
the same fuse. As a result only one function can

be used at a time. Failure to do so will result in
a blown fuse, disabling trailer tow functions and
rear outlet functions. This will cause the trailer
to have no trailer lights.

the troubleshooting guide on the back of this card. Please reference the vehicle
