Well, the battery is not the problem, it's brand new, fully charged and shows great voltage under a load. However, the motorcycle still will not turn over. I put the load tester on the battery while it was installed in the bike, turn the key and there wasn't any voltage drop when I pressed the start button. The weird thing is, at least with the bike, usually when I turned the key to the on position I always heard what is best described as a humming sound. My guess is it's either fuel pump priming itself or the injector pump coming up to pressure. Now, I only hear the noise for a very brief moment, maybe a half second, normally it makes it the humming noise for about 2 or 3 seconds. Your thoughts and suggestions are always welcome. Roger
