I purchased a battery for our 2010 cruise lite. It's been on the rig for 6 hours now while the rig is plugged into shore power. I am seeing zero progress. Anything else I should look for that could be preventing it from charging? The sticker on the new battery had a date of 7/15. Thanks.
How do you know its not charging? Have you measured the voltage at the terminals? If the converter is working and connected to the battery, the voltage at the terminals should be about 13.6 volts or more depending on the battery's current charge. A fully charged battery, disconnected from the converter should read around 12.6 volts.
The converter is the box with all the fuses in it, normally it is the main ac and dc fuse location as well as the converter section that cannot really see from the front.
It looks something like this a brown or black box with a plastic flush cover door.
First unplug your camper from the shore power and then read the voltage across the battery. If it is still about 12.8 volts the battery is fully charged.
Well if it is reading 12.8 volts the battery is fully charged and therefore not the problem. Make sure that the battery is not connected backwards in the RV, positive from the battery should be going to the coach main converter fuse panel. The negative lead from the battery is connected to the frame of the unit and you can normally see where it is connected to the frame close to the battery. Also make sure that if you have a battery disconnect that it is not operated cutting off the battery from the coach.
Follow the positive lead from the battery and you should find the fuse you are looking for and the reset button. On a travel trailer many times the fuse is on the underside of the frame going to the coach.
