How to Wire the House Batteries in Your RV

Someone, please My 1992 Allegro Bay RV’s battery terminals need to be connected, and I need assistance.

It has three batteries: one that starts the engine, and the other two are for the generator and the inside.

I’m a woman, and I have no idea.

I already appreciate any assistance.

ANSWER: Let me begin by noting that if you have any questions regarding how to connect the batteries in your RV after reading the plan below, you should ask a friend or neighbor who is more experienced to assist you.

If this procedure is carried out wrong, it might seriously harm your batteries and the 12-volt system in your RV.

Additionally, there is a chance that you’ll ignite an electrical fire inside your RV.

This information is not intended to alarm you; rather, it is intended to alert you to the possibility that hiring an RV technician may be preferable.

The cost of doing the task properly will be far cheaper than the expense of fixing your motorhome’s electrical system.

So with that stated, let me begin with the rules.

I’m thinking the RV doesn’t have any batteries at the moment.

If the original batteries are still inside the RV, all you have to do is connect them in the same manner.

Two 6-volt batteries connected in series are what I’m thinking are being utilized on your RV for the house battery system.

By glancing at the top of the battery, you can determine whether they are 6-volt batteries.

On top of a six-volt battery, there will be three fill caps.

When they if two 12-volt home batteries each have six caps, they are 12-volt batteries, and the wiring schematic that follows will not function for them.

Motorhomes With Two House Batteries.

Make sure the RV’s ignition is in the off position and that all 12-volt systems are turned off before continuing.

The starting battery for your RV should be installed first.

You must connect the positive battery cable first after securing the 12-volt starter battery in the battery tray.

The motorhome’s positive battery cable will be a cable that travels to the engine compartment.

The negative cable must then be connected to the starting battery.

Okay, it’s time to connect the motorhome’s two 6-volt house batteries.

To power the 12-volt system of your RV, these two 6-volt batteries must be connected in series.

See how to connect these batteries by looking at the following diagram.

Use the illustration above if your RV has four house batteries.

The issue now is that you need get a qualified RV technician to do the task for you if you are unsure of which wires lead where.

Your RV may include optional power inverters and other electrical equipment that are hard-wired to the house batteries.

Again, the batteries will be harmed if these electrical devices are connected to them improperly.

I hope you found this information to be useful.
