You may not understand this but most electrical circuits are looking for ground.
When the positive shows a reading to ground, chances are, that part of the circuit is working. Think of it like a household table lamp. If you have a light bulb in the socket and you do a resistance check on both prongs that plug into the wall, you have just verified the wiring is good on your lamp. Same thing with your bike. Your circuit might have gone through some light bulbs or something.
