Hi all,

I have recently decided to get a battery isolator for my '88. Question I have is that I have a one wire 115Amp chevy alternator ready to replace the anemic stock unit and I was wondering which isolator unit to buy?

I'm looking at a dual batt, 200amp Cole Hersee unit but I'm not sure if the regular 48160 (3 terminal: batt 1, Alt, batt 2) or the 48162 (4 terminals - batt 1, alt, batt 2, ignition) is for me. The 48162 is stated to be for chevy applications that use AC Delco CS series on chevy or GMC that require B+ present at the output terminal.

What the heck is B+ and which one would be best suited for my application? <img src="/forums/images/graemlins/confused.gif" alt="" /> Thanks in advance!
