How to wire the Dual Battery Isolator - : December 21, 2013 3:50 am The isolator from www.dfna.info is the simplest of all isolators to install.
The “dual sensing” feature of this battery isolator makes it impossible to install backwards. Wiring is accomplished by: Connect a cable from the positive terminal of the primary battery by removing one of the nuts of the threaded studs on the back of the isolator. Apply cable, replace nut and tighten securely.Then connect a second cable from the isolator’s remaining threaded stud to the positive terminal of the second battery.The isolator’s black ground lead must then be connected to a common ground shared by all batteries. The isolators provided on dfna.info are voltage sensitive relays with smart technology that makes them simple in application but provide more efficient operation through elimination of the large diodes in other isolators.

The following are common steps on how to check a battery isolator provided by the experts at www.dfna.info. Set your volt meter to DC voltageTouch the meters black probe to negative terminal of the battery or other common ground.Touch the meter’s red probe to the battery’s positive terminal.With the engine NOT running the reading should be somewhere in the 12.7 volt range.Now start your engine. Immediately apply the meter to the (primary) starting battery. You should see the voltage rising from 12.3 or so upward. Categorised in: Maintenance Tips. How Battery Isolator Works in Your Vehicles - : December 17, 2013 12:36 am An automotive electrical system produces enough electrical power for an automobile to run the ignition system, charge the battery again and supply power for electronic devices inside the vehicle.
Some vehicles take advantage of this extra electrical capacity to sustain a 2nd on-board battery. Typically a vehicle with more than one battery will include a battery isolator in the set up. A battery isolator separates the batteries from one another in a way that allows the charging source to charge them in a designated order. This isolator will not only manage the charging sequence order but also separates (isolates) the batteries from discharging each other if and when the charging source is not producing adequate power.
The TRUE dual battery isolator system is not linked to the vehicle’s alternator or its ignition but instead relies on “smart circuitry” which senses the voltage available to determine when to connect or isolate the batteries. How to install battery isolator for vehicle and boat : December 17, 2013 12:33 am Having a larger stereo in your car means more power being needed to run it.
Thus, you would need to have a second battery installed. In order to do this, a smart battery isolator is needed. The steps in mounting a TRUE smart isolator are discussed in this article. 1. . $129.95 Free Shipping 1 140 Amp Voltage Sensitive Relay1 19’ 8” length of battery cable1 Ground Cable2 Positive brass marine type battery terminals1 Negative brass marine type battery terminalTinned copper lugs, heat shrink & Cable TiesEasy to follow instructions for Dual Battery Wiring Diagram 4.
The second battery, the one you just installed, will be charged only when the alternator has charged the first battery to a level where there is 13.3 volts available at the isolator.

ATV/UTV Dual Battery Management System - : December 17, 2013 12:24 am FactAll of the current charging stators in today’s UTVs will produce a maximum of about 35 amps of power when the engine is running at 5000rpm.
Many such as the Yamaha Rhino produce less than 30amps. UTV Dual Battery Kit.
