Brocott Split Charge Relay Wiring Diagram

The relay will then switch in the alternator feed to the leisure battery to let it charge just like the vehicle starter battery.

Brocott split charge relay wiring diagram.

A range of quality voltage sensing split charge relays from 30 amp relays to 150 amp relays. Select sub category 12volt 180amp 2mtr voltage sensing split charge relay kit 110amp cable. This system uses a heavy duty version of a simple make and break relay the coil of which is energised by a signal that is only 12v when the engine is running usually the charge signal wire from the alternator. This is how you can install your split charge relay.

I have left boxes on the diagram on the left to help you with your measurements. Have a look at the diagram above to see the basic wiring diagram of your voltage sensed split charge kit. Fit the 2 fuses in the fuse holders. This relay is different from other standard split charge relays in that it monitors the main battery voltage and monitors the second battery voltage and only switches the charge to the secondary battery on when required so no over charging can take place and also ensures that the main battery charge is maintained and wont leave you with a flat.

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