The "OL" means an open circuit. If you're measuring between two points that should be electrically connected, I'd expect to see a couple of ohms, not an open circuit. The most common reason would be a bad connection at a connector.
If the BPC ohms out properly (about 3 ohms per leg) and the FET was replaced, yes, it won't blow. But I suspect that when it did blow is what took out the FET in the APC.
Open circuits are really easy to find - just trace from one end to the other, going in steps. Heck, just disconnect each connector, look at the pins for anything obvious, and reconnect them. About 50% of the time the issue is obvious - the pin or socket is pushed back. About 40% of the time you don't see anything, and when you put it back together, it works great. That's because a little oxide built up on the connector pins, and the simple act of disconnecting and connecting it scraped through and all is well.
