Alain -
You may have an overload on the DC output [charging]
portion of your Converter-Charger. There is an auto
reset circuit breaker inside the unit, that looks
like the 30A breaker wired in series with the short
lead between engine battery and the combiner solenoid-
relay. If there is an overload [short, reversed
polarity of rear battery, etc.], this breaker can
trip-reset-trip rapidly.
The overload could be a dead or shorted house battery
or wiring. It's much easier to check rear battery DC
& wires first. Did someone work on rear battery, or
have wires disconnected recently? Winnebago confus"ed
a lot of us with their "house wiring - Black = HOT
DC wiring. VW used conventional "Black = Ground =
Negative". When you look at engine battery, note the
Black wire on [+] terminal, to the little 30A breaker,
then to & from the solenoid combiner relay on firewall.
The Black [+] lead from other sde of relay goes to an
insulated tie point, just forward of the Converter.
The converter is connected to that tie point, & to
rear battery [+] terminal - with a Black Wire.
The Converter plugs into a 110V AC outlet, that is
just behind the Left tail-light, accessible after
tilting the power panel back.
If you unplug this hidden plug, you should still
have 110V AC to the Norcold, & AC outlet above it.
You will not have Converter DC, of course.
If rear battery and wiring are OK, the alternator
should still charge the rear battery, through the
Combiner relay to front battery. Note - check
rear battery wiring before running engine, if
engine has not been run recently. [+] = Black.
Had the van been run or driven recently? How long
has it been since you last plugged into 'shore
power'?
Did you have any DC loads plugged in to any of
the 3 DC outlets? Was the Norcold 'fridge on? If
ON, was "DC" selected?
I'll check PC from time to time, for more info
when you have it.
Do you have access to a volt-ohm-meter?

I have a 96 ev camper, After i plugged the 120 volts on my van , I
had
the electricity working in the van but i noticed that an important
noise came from behind the electric and 12 volts panel located at
the
back of the vehicle under the shower. Taking the control panel off
I
can see that the noise is coming from what i think is the charger
located on the floor. The noise is there till i diconnect (110V)
that
charger or what ever it is or till i jump the ground fault plug,
and
then ther is no more electicity in the van (the 12V is OK).Somebodt
can
help me on that. i dont have the wiring schedule of that system
and
could not find it int the vehicle manual.help would be appreciate.
