Trying to get my '51 GMC 100 running for the first time after buying it. Previous owner said it ran good and he drove it around town prior to parking it. That was about four years ago. I have a new 6v battery, the starter cranks over fine and I get 6v or so on both leads on the coil. The points, condenser, cap, rotor and plugs are nearly new. The coil does not look new. While cranking there is no spark from the secondary output from the coil and all I know past that is that the points are opening and closing. I'm going to do an ohms test tonight on the coil but is there something else I should be checking?

Thanks for any help,
Dan
