How To Install 2 Batteries

Mounting the Second Battery

Start by deciding on a mounting position for the 2nd bombardment in your engine bay. Supercheap Automobile sell battery trays and all necessary accessories for mounting your second battery.

Just be careful to ensure your battery kit has plenty wire to reach the second battery.

Disconnect the Main Battery

Disconnect the negative final from your main bombardment earlier starting whatever more piece of work

Mounting the VSR (Voltage Sensitive Relay)

The Voltage Sensitive Relay or VSR is the computer controller for the two batteries and needs to be mounted where it will be hands accessible. Away from any hot or moving parts and equally close to the main bombardment as possible.

Employ the mounting plate on the back of the VSR to mark and drill four holes, and secure the top right and lower left holes with the curt screws. Then, take the length of ruby cable with lugs at both ends, and mensurate out plenty cable to run from the centre of the mounting plate to the positive terminal of your main battery. Follow existing wiring where possible and avert hot or moving parts.

Cut Cables to Length

Cut the cable to the correct length and repeat this pace this time to the positive terminal of the auxiliary battery.

Fit the Lugs

Fit the lugs to the bare ends of the cable by stripping away xv millimetres of insulation and crimping them in place with the crimping tool.

Slide the rut shrink over the lug and heat it with a heat gun to give it a waterproof seal.

Attaching VSR Earth

The blackness wire attached to the VSR needs to be earthed.

Annotation: It's important that these earths are grounded deeply; where possible use a bolt which has been used to world the engine or other engine component.

Connecting The Primary Battery To VSR

The cablevision from the primary bombardment goes to the VSR final marked with a scarlet dot, and the words "positive sense battery". The cablevision from the auxiliary battery goes to the final marked with the words "positive second battery".

Earthing the Second Battery

Your secondary battery volition need a solid earth as well. Take the 24 inch blackness earth cable and again secure to a factory engine basis or similar.

Attaching the VSR to the Mounting Plate

The VSR can now be attached to the mounting plate using the two longer screws, and the positive cables may exist attached to the chief and secondary batteries.

Attaching the Negative Leads

Then secure the negative terminals - beginning to the primary bombardment, then to the auxiliary bombardment. Use the cablevision ties supplied to keep your wiring corking and safe.

Testing the New Dual Battery Kit

If you want to test your new setup, y'all tin do and so with a multimeter. Start the vehicles engine and take a reading from the principal battery. Once the voltage climbs above 13.3 volts, you should hear the relay click and the red low-cal illuminate; to evidence that the second bombardment is connected. Now turn off the engine and take a reading from the main battery over again. Once the voltage falls below 12.8, the relay should disconnect. To speed upwardly this process, you may wish to switch the headlights on. If everything works as per these tests, you lot have successfully installed your ain dual battery kit
