Narrative:
On a part 91 flight from (yip) to (air driven generator) we received vectors from toledo approach control for the NDB runway 5 (air driven generator). After receiving and identing the inbound course, we began descent to about 500 ft above MDA. Approach control then issued altitude alert and advised 3 mi north of course while our ADF showed on course. While correcting course, we broke out in VFR conditions northeast of airport and canceled IFR. If I was in command, I would have gone missed and diagnosed for equipment malfunctions.
