Battery isolator for 1997 Chevrolet k2500

Question:

Tried to install a isolator I had on a 1998 Dodge truck. Isolator only has three posts. Main battery, alternator and auxiliary battery. Does not work properly. Looking at Deka 120amp DW08771 with 4 posts. Will this work on my 1997 Chevrolet k2500? Thanks

In order to determine compatibility of the Deka Battery Isolator - 120 Amp part # DW08771, the amperage rating must be above of that of your alternator to prevent any damage to the isolator. That is the only thing that determines compatibility.
