Why do my lights not come on when not connected to shore power?

With 12 volts present when the charger is running when on shore power, one would suspect there is a wire routing issue, as you should get 12 volts from both the charger and or the batteries if things are connected properly. I have a feeling that you do not have 110 volts from the inverter output when you are not connected to shore power.

Why does my RV get no power when plugged in?

Sometimes your RV gets no power, even when it’s plugged into a shoreline power source. This could be because of any of the electrical components within your RV: the wires, outlets, circuit breakers, or transfer switch. You’ll have to test each component one by one to diagnose the issue.

Why do my house batteries not charge when I run the engine?

They will read very low if no charging voltage is present. The house batteries (as well as chassis batteries) should charge when the engine is running, if not then you should find a fuse in a positive 12 volt feed between them and the alternator.

What’s the voltage of a car battery with no power?

ASSUME YOU MEAN WITH NO SHORE POWER AND ENGINE OFF– THAT VOLTAGE IS OK– ABOUT A 40% DISCHARGED BATTERY. The Chassis battery running is 14.35. VERY GOOD– THAT IS WHERE IT SHOULD BE.

What happens to batteries when plugged in to shore power?

When plugged into shore power at the campground, presumably the AC to DC converter will charge the auxiliary battery bank. All the lamps, fans, water pump, etc., still operate on 12-volts DC, just that the DC electricity is provided by the converter instead of the batteries while plugged in.

Why are the 12 volt lights working on shore power?

With the 12 volt lights working when on shore power means the charger is working. Look for a large fuse between the batteries and the charger 12 volt output feed to the positive coach battery terminal (s). With a meter you should read a voltage at the positive terminals. They will read very low if no charging voltage is present.

When does an RV charge when plugged into shore power?

Fortunately, the answer is yes; your RV house battery will charge while it is plugged into shore power. Your RV battery will charge when an external power source is connected and providing power to your RV. In addition to shore power, your RV battery will charge when your generator is running, the vehicle engine is running, or through solar panels.

What to do when your shore power goes out?

With your shore power unplugged and the generator turned off, open the transfer switch and see if you can see any damage. You may find some burnt terminals or wiring, or some scoring in there. Everything was running fine and the power went out in the middle of the night.

Can a generator be plugged in to shore power?

With the shore power plugged in, take note of the position of the relay contacts. Then start the generator and see if the contacts switch over. It indicates Air Cond The wire coming out of the box also has written on it “front AC”. It is 30 amp. When plugged up to shore power, I get nothing.

Why does my generator not run on shore power?

this sounds like a problem with your transfer switch. If you don’t know, this is the device that switches the power between the generator and the shore power cord. It probably has a damaged relay and cannot switch over to shore power. You should find the transfer switch behind the converter.

Why does my AC not work with shore power?

When I put power to the shore power side, the AC works but nothing else does. When generator is on everything works. Seems like there may be another switch between shore power and this switch for some reason. AC probably means “Alternating Current”, not “Air conditioner”.

Why are the lights not working on my FMCA RV?

Welcome to FMCA ! Sounds like a possible transfer switch or fuse issue. With the 12 volt lights working when on shore power means the charger is working. Look for a large fuse between the batteries and the charger 12 volt output feed to the positive coach battery terminal (s). With a meter you should read a voltage at the positive terminals.

What’s the battery voltage on a motorhome with no power?

The batteries not running are all 12.58. ASSUME YOU MEAN WITH NO SHORE POWER AND ENGINE OFF– THAT VOLTAGE IS OK– ABOUT A 40% DISCHARGED BATTERY. The Chassis battery running is 14.35. VERY GOOD– THAT IS WHERE IT SHOULD BE.
