Question about RVs

1 Answer

2012 Grey Wolf 28BH. All works on shore power. Nothing works on DC only. No fuses or cutoffs visible on DC feed. All DC fuses & reverse polarity fuses are good. Is there an inline fuse anywhere?

Converter provides 14V on shore power, battery does not provide 12V to converter when shore power disconnected. Batteries have full charge. Assume short in battery feed. Is there anything obvious to check. Do I have to remove chassis undercover to get to the main battery feed wires? Do the feed wires run near the port side wheel well which was recently repaired by dealer?

You need to use a multimeter and check solenoids. does it have power when motor or generator is running?

    This is a TT. No generator or motor. Would Forest River have hidden a breaker or switch that is not user serviceable?

Wiring diagram for a 1988 sunline travel trailer.some of the light switches and outlets have no power going to them.what could be the problem?


Your trailer has two electrical systems, 12v and 120v. The 12v system has a battery and perhaps a converter/charger to power it. The 120v system must he hooked up to 'shore power.' Both systems have their own protection. The 12v system has a fuse panel, check for power at each fuse. 12v wall switches are often smaller and don't look like typical 120v switches like in a house.

The 120v system has a breaker box and circuit breakers. Reset each breaker by turning off then on again. In addition, the 120v outlets might have a GCFI outlet near a sink. It often is wired first in a breaker circuit, thus giving GCFI protection to other outlets in the circuit. Test the GCFI and make sure it clicks off and can be reset.

Outlets not working all fuses are good


120-
VOLT
AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

SECTION 6 - ELECTRICAL SYSTEM JAYCO TOWABLE
6-2
120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

How do I get my Thor Freedom Elite outlets working? I have already pushed the reset button on the GFCI but stlll not working. any suggestions?


First, the GFI runs on house current aka shore power. Make sure you are plugged in! Most GFIs have a light showing power on.

Check your breaker - not a car type fuse - in the fuse panel. GFIs are nothing but a quick-disconnect in case of a short. (Quick description)

You really need a wiring diagram for this. Try and get one online or from the mfg.

Start by tracing back towards power source from GFI. Remove GFI and check for power on the wires. Be careful, it's 120vac house current. If you have power, replace the GFI. If no power, look at the diagram and proceed to the next outlet/GFI on the same circuit. You might have to go all the way to the power distribution panel. Sooner or later you will find the open wire. Might be nothing more than a screw vibrated loose disconnecting the power feed.

2012 Thor Challenger 36FD; Auxiliary batteries went dead, tv recepticals and generation not kicking on. Charged batteries, but no change. Is there a reset button or maybe a fuse that I might need to...


If the unit has a transfer switch that switched between generator and shore power you need to look at that since nothing is working with the unit plugged into shore power. There may also bee a few battery disconnect switches close to the batteries. In that system there should also be a few inline circuit breakers. If they have tripped they will need to be reset. To determine if they have tripped you will need to look at the circuit breaker and see if there is a small black lever hanging down. If there is, slide it back up and it will lock back into place and should restore power. Without actually seeing the coach and the power configuration it is difficult to determine exactly the problem. Hope this helps.

1989 damon escaper ultrasport, at full hookup site A/C working fine until it just shut off. At that moment I was programming fridge because it wasn't cooling. Might be irrevelant but fridge now...


Your AC (air conditioner) would only run on AC (alternating current - shore power) so there would be a circuit breaker. Fuses are for DC (direct current - batteries).

That said, 16A is a very odd number for a circuit breaker (or fuse).

Your AC will only run if you are connected to shore power or have a generator. (Very large inverter and a lot of house batteries is technically possible but very unlikely and it wouldn't have been built that way).

If your AC actually draws 16A then being connected to a 30A outlet is fine, I have actually connected mine to a 20A outlet at home to test it but I made sure nothing else was turned on fridge, heaters, water heater etc).
