Thanks Tom for the explanation. My Tach has an integral light in it and when wired as you have it the light stays on. But it seems my Tach also has a ground wire and yours does not. So I rewired so the switch is before the coil and the coil does not see voltage until the switch is turned on. That is why I asked.
