![]() ![]() ![]() It will defeat the purpose of the isolator to leave the batteries connected with a switch or solenoid. It should be push button controlled and used only in case of need. 311K subscribers 568K views 10 years ago Learn more about battery isolators and why you need one if your car audio system has 2 or more batteries. The solenoid should be capable of carrying starting current. I go over how you can diagnose an issue with yours, the installation and a wiring di. When installing an isolator on a GM 'CS' series alternator equipped vehicle the general isolator installation instructions on page 2 of the instruction sheet must be followed in addition to the group 2 instructions as shown here. Hello again This is a video of me replacing my PAC 80 battery isolator. It is two separate battery systems charged (through the isolator)by a single alternator.Ī push button controlled solenoid may be added to temporarily connect both systems together should the need arise. (See below for plug connector identification). The isolator diodes prevent either battery from feeding the other system. The alternator outputs the maximum charging voltage and any/either battery that is below that voltage will charge until it is up to the charge voltage. It can be fitted to all 12V vehicle types. As I mentioned in the video the smart battery isolator is an easy and cost effect. Easy to Install The electronic isolator does not require any changes to the vehicles existing wiring. The REDARC Smart Start SBI12 100A is a 12V DC 100A microprocessor-controlled, dual battery isolator designed to protect the start battery from excessive. The power out wire from the alternator is connected to the input of the regulator and the two output terminals of the isolator are connected to the two battery systems.Īutomotive charging is voltage controlled, not current controlled. I recorded these videos in February of 2021 and only got to posting it now. I'd be very interested to know any other arguments for +ve or -ve isolators.If you are driving a vehicle that presently requires two batteries, it may be better to add a third battery (via an isolator) for your accessory loads. Hello, I am installing a 12v system (2x 6v 225ah AGM batteries in series) in my 05 Sprinter home conversion and hoping for some assistance/guidance. When sizing the cable I would recommend following the battery isolator's instructions as they will generally have a chart covering the proper size cable given the distance to the. Look at your battery installation and if it is at all possible to contact an opposite polarity connector or bus-bar with tools then I'd put the isolator on the side that isolates the potential hazard - like the car body example. Battery Isolators make sure the starting battery is taken care of first, and then once the starting battery is charged it switches to the auxiliary battery bank. connected directly to the battery clamp) then IMO, on a boat it doesn't really matter if the isolator is on positive or negative. ![]() Obviously a plastic boat can't be "earthed" in the same way, but often negative bus-bars or connections are left un-insulated - as is the engine - so the same convention is used.Īs long as there is nothing by-passing the isolator (e.g. This means that any failure of insulation on positive wiring, or contact with metal tools to the body when working on positive wiring can easily cause a short - The isolator on negative ensures the body is isolated first to allow safe working on the vehicle positive circuit. that is, the body of the vehicle itself is connected to the negative terminal of the battery. Putting the isolator on the negative lead is a convention from vehicles where they are "negative earthed". ![]()
