It's a very simple circuit. Make sure your battery connections are good and clean. Test your battery. Measuring it statically without a load on it won't work. If you have to take it to your parts store for testing, do so. If the battery TESTS good, using your volt meter, connect the meter's negative to the battery's positive clamp and use the meter negative and probe the start switch as you press the start button. IF that checks, go to the starter connection. My guess is either bad electrical connections or the mechanism between the start button actuator and the starter switch has a problem where it is not closing the start switch. I had that problem before. It was a worn starter switch. It tested good electrically but mechanically, its button was sitting too low and the start button's mechanism couldn't push it in far enough to close the starter switch.
