However some owners have installed a "latching" relay that remains "energized" without drawing any electrical power and will keep the banks connected until it's "released". The boost switch on the instrument panel pulls in a relay that connects the two banks together until you turn the switch off. 200 Amps at 12V Continuous Power Handling. Does not create a voltage drop to the second battery like conventional isolators. Great for isolating a second batter making it dedicated to the stereo system. This, as explained by jcus, is one of those. Microprocessor-Controlled 200 Amp, Dual Sensing Smart Relay Battery Isolator. When the engine is started and either battery reaches 13.4 volts, the relay engages (blue LED on), allowing two battery banks (start and accessory) to be charged simultaneously. There are previous-owner installations of trickle-chargers for the start bank, solar panel charge controllers with a link to the start bank (normally solar panel systems only charge the house batteries), etc. Smart Battery Isolator Installation Instructions The smart battery isolator allows two batteries to be charged at the same time. Shore power (via the converter/charger) will charge only the house bank. The generator will charge only the house bank.ģ. The engine alternator will charge both banks.Ģ. It looks like someone has modified your system. ![]() Unless someone has modified the system the (or you turn the "boost" switch (on the dash) on) the two battery banks are isolated from each other in such a way that the house side cannot draw current from the start side and vice-versa. It is that large heat sink unit below the "black box". There is already an OEM isolator that protects your start battery bank from being drawn down by the house battery bank. Sorry to be so paranoid about taking care of the new batteries we installed, but they weren't inexpensive and I'm kind of working my way through the entire system, the inverter/charger dip switches, this "black box," and whatever else might threaten them. My memory of the long and good PDI the previous owner provided is that it is was installed to ensure the chassis batteries would always be able to start the coach (i.e., would draw off the house batteries, in the event chassis batteries went down, 120V pedestal was not available, and - I guess? - generator wouldn't run?). Seeing that, however, I'm afraid I still have the question - "What is this?" Sorry to be clueless on this and with thanks to you both (and anyone else who chimes in). IP65 Weatherproof,Outer plastic-housing and a silicone sealed internallayer, protects your isolator from water,dust,dirt,sand damage.This compact battery isolator has an ultra-small size :2.62. ![]() All I did was drill down to the model number. Thanks for the initial search Peter & Beth. Thanks! I guess I should remember, "When in doubt, Google it." This appears to be what is installed (minus the clear cover).
