Hello i have a honda 3500sx it was running fine then the power went out it now has no out put at all no 12 volt no 120 v. no power before the breaker either.

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.

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.
What was the voltage that you measured? Are the units 220 volt or 120 volt. Units that size are usually fed by 220 volts. What is the current rateing of the circuit breakers? Are they a double breaker with a handeling capacity of 20 amps or are they 15 amps.
You didn't mention if they ever worked? Are you feeding 120 volts or 220 volts to the two units?
check the fuse for the 12 volt system. Check wiring for the 12 volt side of the transformer and check if you are getting 12 volt out of the transformer.
A number 12 copper supply cable at the voltage is overkill for this load.
Ohm's Law states: Watts = Volts x Amps. To find Amps: Amps = Watts / Volts. This is 1500W / 240V = 6.25 Amps. Since the max continuous load for a 14 copper is 12 Amps, this size wire is the correct size.
Check to make sure the heater is in fact a 240 volt type, as if it is a 120 volt type, you are likely instantly burning out the heating element. If it is indeed a 120 volt heater, you will need to connect to a single pole 15 amp breaker and place the other wire that was on the breaker to neutral to provide the correct voltage. The load will still be 1500W, but at half the voltage, the current will double to 12.5 amps, and may cause the circuit breaker to trip after a while.
A 20 Amp breaker will support 2400 Watts with a 120 Volt line.
120 Volts times 20 Amps (Amperes) = 2400 Watts.
Answer? 24 100Watt light bulbs.
HOWEVER, you should always allow 1 cushion of 100 Watts. That would be 23 100Watt light bulbs.
(Wait until you add electric motors to the equation. Things start getting a little more complicated)
(I always use 20 amp breakers for lighting. 15 amp breakers for lighting is phased out.
Secondly a 20 amp breaker requires using 12-2 or 12-3 wiring. (12/2, 12/3) SO does the receptacles.
Therefore 12 gauge wiring is used throughout the house, until you come to the heavier loads )
[ 12/2 = 2 insulated conductors, and one bare copper ground wire. 12/3 = 3 insulated conductors, and one bare copper ground wire.
Remember, with 12/2 the Black wire is ALWAYS the Hot wire. White is Common (Neutral). Bare copper is Ground wire.
12/3 has 3 conducting wires. One Black, one Red, and one White for the Common. (Neutral) Bare copper is Ground. Used for 3-way switches ]

Hello, test for 24 volts between r and c terminals and for 120 volts at L1 and neutal on the control board, if ther is voltage to the board then the control board is faulty and must be replaced.
