Wiring in the second battery is as simple as following the C/H wiring diagram. When you start the truck, the charging system brings the cranking battery back to 13.2 volts (full charge), then the isolator closes, the red status light turns on, and the alternator now recharges the auxiliary battery. Battery isolators are designed for vehicles and equipment with multiple batteries - one for starting the engine and another for powering accessories. This separation protects the starting battery while allowing the auxiliary battery to continue to power the auxiliary loads. When the isolator senses the batteries reach 12.7V it opens the solenoid relay to separate the two batteries and turns off the status light. 12V 140 Amp Smart Dual Battery Isolator Voltage Sensitive Relay Kit (Fits: More than one vehicle) 129.19 Was: 151.99 13.00 shipping or Best Offer SPONSORED Battery Voltage Stabilizer Improves Alternator Battery Performance for GMC (Fits: More than one vehicle) 40. Either that, or directly to the battery or starter relay. SMART IOSOLATORįor example, you pull the truck in to a jobsite, turn the engine off and leave all the warning lights on. Intellitec’s Battery Isolator Relay Delay/E offers a low cost, reliable approach to charging multiple batteries. So instead of the normal 'simplified' version of a 3g install, where you connect a short Yellow w/white wire directly to the output of the alternator, you need to run a longer version of it from the BAT 1 post on the isolator, back to the alternators I wire. This 200-amp isolator senses the voltage of both main and auxiliary batteries and connects/separates them according to their charge, always protecting the main “cranking” battery. To connect the two batteries properly, we selected a Cole Hersee Smart Battery Isolator (#48530) designed to work with today’s electronic charging systems. 5781250, Battery Isolator 200A M8 Single Pole Removable Key 45 Deg, 35.200, KISSLING ELEKTROTCHNIK. If you had some load connected to the second battery which could draw over 80a while the engine is running, AND had an alternator that is capable of putting out more than 80a, then you could overload that solenoid.Ī 1000w inverter could draw over 80a, so you'd want to try not to run any loads greater than that from an inverter while the engine is running.The Odyssey is far more receptive to deep discharging and resistant to the hard pounding from off-pavement use than the OEM battery. Just charging up the second battery - no problem. First, locate the starting battery in your engine bay. One is arranged by product group, the other is listed alpha-numerically by model. This is a typical mechanical relay that is used for battery isolation and this model is able to handle 200 amps and will isolate two batteries. With a time factor programmed, if battery voltage is less than 12.1 for 3 minute's, a reset is required, no more high amp loads or it will happen again with less time due to less AH/voltage available. To view or download the instruction manual of your choice in PDF format, determine the specific model number of the product, then simply click on the appropriate link in either list below. Use voltage set point, when a load is active the battery voltage is always less than non load. They can be mounted in the positive or negative side of the battery run. Welcome to NEWMARS installation and operation manual Library. As long as you stay below that, then it will work fine. These are spliced into the battery cable, and flipping the mechanical switch 'cuts' the cable. The solenoid you linked to has a continuous duty rating of 80 amps. The factory AC-Delco Group 48 battery is unique to GM trucks, and it’s rated at 615 CCA (Cold Cranking Amps) with 110 RC (Reserve Capacity). That setup is preferred over diode-type isolators (the ones with the heat sink that you see at auto parts stores) because they don't drop the voltage passing through them like a diode does. We purchased a GM Battery Retainer (14005061) that cost less than 5, along with a second battery and and a battery isolator designed to work with the new electronics. What is being done on that page you linked is a pretty common setup called a "split-charge relay". Relay / Phase terminal carries half system voltage and may be used for certain types of control relays, charge indicators. If you are going to use it to tie the two batteries together while the engine is running, and separate them when the engine isn't running, the it -is- an isolator.
