How to charge auxilliary The vehicle pulling the
trailer is a Scania. Not sure
of the alternator make. We
have fitted 2 batteries (24v)
to the trailer so that the
tail lift and interior
lighting will work
independently when unhooked
from the Scania. Does anyone
know how to keep the
auxilliary batteries charged
via the Scanias alternator.
We've used blocking diodes and
multi-battery isolators on
Rigid vehicles in the past but
not sure about semi-trailers.
There would have to be some
type of coupling between the
Scania and trailer. Also the
wire from the isolator to the
Scania batteries would be
short while the wire to the
auxilliaries would be about
30ft.This would cause a
significant voltage drop and
the split charge would be
uneven. Any auto electricians
out there with sound advice.

Are you sure that this thing is wired for 24v in series or is it wired 12v in parallel like a diesel so that you get more amps. I am thinking that you would more likely be at 12v and if this is the case, it wouldn't be anything to run 2 gauge wire to a plug from the truck battery and a 2 gauge wire from the trailer batteries to another plug where they can be broken behind the cab when you split the units apart. Since you will not be using the inside lights or lift gate, constantly, you shouldn't be too concerned with the voltage drop. This way when you have them together, it will constantly be charging. |

it will fit in a 14 foot door unless you get snow build up in front of it but the ceiling needs to be higher so the door has room when up for all the track,and the lighting if installed,16 ft is probably minimum for inside,most semi trailer will be around 13 ft 4 inches with low profile tires |
