Had the exact same problem with my Lance, same isolator - clicking, no charging. It was the same Sure Charge but not in the recall numbers - although it failed in the same way as the recalled isolators. Lance replaced the isolator under warranty, I installed it and it worked fine for a couple months. Then same thing, clicking no charge. Had a discussion with Sure Charge supervisor several times - essentially, got blown off.
Finally, bypassed the isolator and everything charged as it should. So, took the isolator out of the system and have had no problems with charging since.
I have a disconnect in my truck, so won't discharge my truck battery ... but if I install another isolator, it definitely will not be a Sure Charge. They allowed some into the recall, but the same issues with others on both sides of the recall numbers are the same failure issues. They should have backed up all of the failures, not just a convenient few ... just my 2 cents
