Split Charge Relay Circuit Diagram

One should go in between the lead that goes from the starter battery to the split charge relay and one between the split charge.

Split charge relay circuit diagram.

The other and much easier method is to use a volt sensing circuit which detects a rise in voltage when engine running and energises the coil of a split charge relay to charge the leisure battery. Existing wiring not shown for clarity. Most kits will also come with the instructions so you should already have a ruff idea on what needs to be done. Fit the 2 fuses in the fuse holders.

Whatever split charge system you opt for the most important aspect is to ensure that all connecting cables are protected by appropriately rated fuses to prevent an electrical fire. Instillation guide for a 12v voltage sense split charge relay system thank you for purchasing this kit from simply split charge. How does a 12 volt relay work. Each battery that connects into the split charge device should have an appropriately rated fuse installed in line with the.

Protecting your split charge circuit. Have a look at the diagram above to see the basic wiring diagram of your voltage sensed split charge kit. I have left boxes on the diagram on the left to help you with your measurements. This is how you can install your split charge relay.

The relay will then switch in the alternator feed to the leisure battery to let it charge just like the vehicle starter battery. A 12 volt relay often called a manual split charge relay is an electronic device that uses an electromagnet to pull a set of contacts that make or break a circuit. Ensure this cable is thick enough to carry the maximum charging current of your alternator.
