I think you can continue to use your current Link battery monitor and use a different regulator, such as Balmar. I say this because I burned out my Ideal Regulator last year or the year before and while it was in the shop, I had a cheap $15 Napa voltage regulator plugged into my alternator so we could continue to use the boat on weekends.I forgot to mention, mine already failed...I think. Alternator was rebuilt and tests fine so I believe the regulator module is the problem. I found a place in NJ that does repairs on them, so I am sending it in. Still thinking of replacing the Link 2000R with a Link 2000 and separate regulator.
