I am getting ready for a first start and am busy checking all systems prior to a start. The dizzy is a Professional Products unit and I am using a run of the mill canister type coil. With the ignition on, I am getting 12V between the positive terminal and ground. No voltage on the negative side and no voltage reading between the positive and negative terminals. Positive terminal has the orange coil wire, purple tach wire and positive lead from distributor. Negative terminal has negative lead from distributor. Does this sound right? For some reason I was expecting some kind of reading across the plus and minus terminals with the ignition on. Thanks in advance for comments.
