Split Charge Relay Clicking

Clicking noise in your car s fuse box is caused by a relay that is turning on and off rapidly this can be caused by a computer failure resistance in the ground wire for the control side of the relay or high resistance in the power supply to the control side of the relay.

Split charge relay clicking. 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. Hi i have a split charger to charge the leisure battery up via the engine running i also have a 240v charger which i use when on 240v hook up but the issue i am having is when the battery charger is switched on via 240v hook up the split charger light comes on and then once the battery charger is removed from the leisure battery the split charger light still stays on. My problem is that the split charge relay constantly clicks and only stops when i. Typically split charge relay is controlled by the ignition wire so that when the engine is running ignition is on the split charge relay will close and connect both.

I have a vw t5 with a 12v leisure battery connected to vehicle battery via a 140a sensitive relay portable power technology. A 12 volt relay is the same type of relay that you would find in many 12 volt electrical systems. Voltage sensitive charging relays. To find out the source of the problem you ll need to run some quick tests using a multimeter.

Dc dc b2b charging kits 12 volt. The charging system uses a heavy duty voltage sensitive relay vsr which is connected between the 2 batteries the cab battery being the voltage sensing battery with the engine running the voltage on the cab battery rises to 13 4v the relay switches connecting the 2 batteries together for charging the relay is supposed to switch off when. Both voltage sensitive relay and split charge relay are used to manage batteries in a dual battery system which usually consist of a main battery and an auxiliary battery. I have a cbe charger system and solar panel control i have fitted a lifos lithium leisure battery and reset the solar panel to gel battery at 14 4 volts and the main charger too the lifos engineer said the optimum charging voltage is 14 3 the problem i have is the cbe split charge relay starts click on and off continues when leisure battery is fully charged with no electric hook up on only.

I have fitted a 150w solar panel and smartsolar controller mppt 75 15 to the leisure battery. 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.
