I have a Honda Magna 2000. After a long winter the first time when I tried to get the bike started, I pushed the gas hard then suddenly the engine stopped cranking and light went off. I checked the main fuse and all the other fuses and found OK. I measured the battery and found it was fully charged then I turn the ignition switch on, the light didn`t turn on and no response to the push start, like it has no power. At this time I measure the battery with a meter and found there were no reading like a dead battery. What could go wrong?
