Split charging relay smartcom voltage sensing the traditional method for split charging is to take a wire from the ignition to energise a relay when the engine is running.
Brocott split charge relay wiring diagram.
Have a look at the diagram above to see the basic wiring diagram of your voltage sensed split charge kit.
A range of quality voltage sensing split charge relays from 30 amp relays to 150 amp relays.
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.
Instillation guide for a 12v voltage sense split charge relay system thank you for purchasing this kit from simply split charge.
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.
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.
The relay will then switch in the alternator feed to the leisure battery to let it charge just like the vehicle starter battery.
