If the coils are getting 12V and not working they are bad. Coils are bad to fail when they get hot. I have a 1964 Ford that started up just fine, and ran fine until the engine got nice and warm, then it started to misfire. I traced the problem to an intermittent open circuit in the coil. A ne coil fixed it. The "pickup coils" on a Vulcan 750 are nothing but Hall Effect sensors that take the place of the points, I prefer points myself, but the sensors rarely cause problems. Hopefully the new coils solve the problem.
Your Vulcan 750 does not have a computer. Isn't that wonderful?
