COLE HERSEE 48530 SMART BATTERY ISOLATOR 200A COLE HERSEE HOW TO

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. Four 9/32' (7.2mm) diameter mounting holes.Terminations: three 5/16' (7.9mm) studs & one No.10 stud.Thus the 48162 with a rating of 200A has a per leg rating of 100A per leg. All Cole Hersee battery isolators have a per leg rating equal to half the alternator rating. A 4-stud battery isolator can be used with older pattern alternators (in this case the 4th stud will remain unconnected), but a 3-stud battery isolator cannot be used with the Delcotron-type alternator.īattery isolators also have a per leg rating which indicates the maximum current it can deliver to either battery. The newer alternators were first introduced by Delco and are therefore sometimes called Delcotron-type alternators. The small 4th stud is for connection to a circuit switched by the ignition switch. Most alternators on new vehicles have an integral electronic voltage regulator that requires the use of the 4-stud battery isolator. The amp rating of each item is the maximum alternator rating. The integral heat sink provides efficient heat dissipation. The electronic components are embedded to give excellent protection from adverse conditions, such as contamination and vibration. Use general purpose battery isolators for 12-36V DC negative ground systems. In addition, both batteries can be charged simultaneously from one source. Battery Isolator For vehicles with two batteries, these devices electrically isolate the batteries to prevent the battery with the higher charge from draining into that with the lower charge.
