Battery

[Brandon327]

How long should it last? On our way home from Orlando 14 hours by the time we got home it was almost dead. All it was used for was the fridge the whole trip and a light or 2 and the water pump on potty breaks.

It seems as though the truck should he charging it.

have you tested the 7-pin plug to see if the charging wire is charging? some vehicles need a fuse activated for this to happen.

+1.

Test between pins 1 and 4 on this diagram. Should read Tow Vehicles charging voltage from the alternator. Also bear in mind some manufacturers turn the 7-way 90 degrees right or left. So pay attention to the orientation of the key at the "top" of the receptacle when testing.

I agree with Dan. Check the plug. If charging correctly, a long drive like that should have been sufficient so that's probably the problem. Also, check to make sure the battery was not disconnected (there may be a switch near the battery).

As for "how long should it last?" This is also dependent on the size and type of battery. A small group 24 is usually a marine battery built for double duty. These won't last as long as a large deep cycle battery. What do you have?

Even if the truck was not charging the battery, it should have been in better shape. That's was a pretty light load for most RV batteries. I would have the battery load tested and check to see if the truck is charging it. BTW, measure battery voltage with the shore power disconnected. Note the reading. Now connect the truck and leave the motor running. Recheck the battery voltage. You should see an increase in voltage from the two readings.

What would cause the converter breaker to trip?

Assuming you're referring to the 120V breaking feeding the converter... Any number of thing could've caused this. A short on the 120V side of the converter would be top of my list. Generally, most converters pull 2-3 Amps during low consumption and battery charging. Shouldn't normally be anyway near the 15A necessary to trip a breaker. Less likely but still a possibility is a faulty breaker. Also, it may not be your breaker.

Check your battery voltage. Then connect the RV to shore power. The voltage should being to climb as it charges. Make sure your converter is functioning properly.

Some of the things that can cause the converter breaker to trip are:
Defective converter, converter plus and minus connections reversed, a short on the output side which could be the battery. A battery can short internally which would cause this. Take your battery to your local auto parts house and ask them to test it. Disconnect the battery from the converter and see if the breaker still trips. If it does, it is most likely the converter has failed.
Let us know what you find.

This is the second time the converter breaker has tripped in the last few months. When I reset it if works fine .
