Installed a Bosch tach this morning. Everything is hooked up per the instructions with the green wire going to the negative side of the coil. It’s been upgraded to the MSD electronic ignition. Tach comes on and jumps to 0 when I start it but RPM’s aren’t registering. Any ideas? 2F stock motor except for the electronic ignition.
