Installation: Four 9/32' (7.2mm) diameter mounting holes.Īll orders from Boat and RV Accessories may be returned within 30 days from date purchase for a full refund less shipping charges, and a 20% restocking fee if the item is not in its original condition.Terminals: three 5/16' studs and one #10 stud.Rating: 12-36V DC 140A max alternator rating negative ground electrical system only.Isolates loads of 2 batteries, allows charging from 1 source.For use with Delcotron-type alternators.Thus the 48122 with a rating of 140A has a per leg rating of 70A per leg. All Cole Hersee battery isolators have a per leg rating equal to half the alternator rating. Battery isolators also have a 'per leg' rating which indicates the maximum current it can deliver to either battery. 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. 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 of the 48122 are embedded to give excellent protection from adverse conditions such as contamination and vibration. For vehicles with two batteries the Cole Hersee 48122 isolator electrically isolates the batteries to prevent the battery with the higher charge from draining into that with the lower charge.īoth batteries can be charged simultaneously from one source.
