How long should a trailer battery last?
The bottom line is a little routine maintenance and recharging a discharged battery as soon as possible will extend the life of the battery. RV batteries can and should last 5 to7 years, rather than 1 to 2 years.
How are trailer lights connected to the battery?
The wires can be connected to the battery using electrical tape to secure them in place; for a more secure and professional connection, though, first connect the wires to automotive battery terminals and then secure the terminals to the battery posts.
Is it possible to charge a trailer battery?
You are more than welcome to try to charge your trailer battery straight off of the 12V power from your vehicle, but in our experience there is enough power lost that you’ll only get a trickle charge on the trailer battery.
What kind of power do trailer lights need?
With two wires extending from trailer lights, the wires are ready for connection to a power source. Since the lights are designed to work on a 12-volt automotive system, the ideal power source is a 12-volt car battery available from any local automotive or chain retail store.
Can a trailer battery be charged by a diode?
You should note that this won’t charge a dead battery, but it will keep the battery topped off when you are towing the trailer. A diode wouldn’t do that – they are just used to keep the trailer wiring from backfeeding to the tow vehicle wiring (as in if the trailer wiring shorts out it won’t damage the vehicle).
When do you charge the batteries in a RV?
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. Check all the wiring to see if its correct, you might need to find a little help if your not familiar with the circuit.
Where does the constant 12v plug go on a 7pin trailer?
They are rear facing lights that mount over the trailer hitch which plug into the factory 7 pin connector. While installing this I found out that from the factory the 7pin connector does not have the constant 12v connected.
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.
Why does my GMC Duramax have no power to trailer?
Turned out that upon closer inspection the 40A fuse for Stud#1 was blown. It looked fine from the top but when I pulled it out it was no good. If it is hooked up and did blow a fuse it would be one of the square ones furthest inboard that protects the #1 post. Your slide must have overloaded the fuse. Mine is a 40 amp if I remember correctly.
