There is no need to disconnect the batteries if the battery maintainer is hooked up and does not get unplugged or lose power.Littelfuse products are not designed for, and shall not be used for, any purpose (including, without limitation, automotive, military, aerospace, medical, life-saving, life-sustaining or nuclear facility applications, devices intended for surgical implant into the body, or any other application in which the failure or lack of desired operation of the product may result in personal injury, death, or property damage) other than those expressly set forth in applicable Littelfuse product documentation. Or, disconnect the negative terminals of the batteries as the "backup" fuse in the Rhino is also always drawing current to maintain memory in the Digital Dash and perhaps CDI. If the machine is to be stored for a long time without a battery tender hooked up, it would be a good idea to disconnect the ground connection of the VSR as it will eventually drain the battery due to the voltmeter inherent to the device. If the relay is unidirectional the battery tender has to be hooked to the Primary battery for this to happen. Now, how that relates to the battery tender is that the battery tender will activate the relay and maintain the charge on both batteries. With the bidirectional type, it matters not which of the 2 big terminals is hooked to which of the 2 batteries.

The owners manual should tell you how to hook it up.
If you are using the unidirectional the relay will be marked with "Primary" and "Secondary" or words similar. The bidirectional senses both batteries and will close the contacts if either is being charged. The unidirectional only senses one of the batteries and will only actuate if the sensed (primary) battery is being charged. Voltage sensing relays come in 2 different flavors, unidirectional or bidirectional. If there is no switch desired then the ground does need to be hooked up, else the voltage sensing will not work.Ĭlick to expand.A battery tender will cause no harm. This optional switch disconnects the ground to kill this parasitic drain if desired. This can discharge the batteries if the machine is in long term storage. The voltage sense circuitry will draw a small amount of current to monitor the battery voltages. The other is showing a switch between the grounding terminal of the separator and the negative return ground. One is a fuse to protect the wiring downstream of the secondary battery. There are 2 optional things that I have thrown in there. Here is a wiring diagram specific to the Rhino that I put together. If the primary battery or both batteries are severely depleted, then the relay will stay disconnected until the primary battery is not heavily drawing down the charging voltage supply.
The primary battery can be charging from a slightly depleted condition and the voltage will be high enough to charge the secondary battery at the same time if it is also slightly depleted. The relay connects the batteries together when the primary battery voltage is a few tenths of a volt (or more) above the nominal 12.7 Volt rest voltage.
