The point side of the coil should have 0v to ground with the points closed, battery voltage with the points open.
If there is 0v with the points open, either there is a short to ground on the distributor wire, or the coil is open internally.
Could also be a shorted condenser, but not likely. New condensers are commonly bad, but not shorted to ground.
Does the coil get excessively hot when running? It should not be uncomfortable to touch, or much hotter than the surrounding components. If it is overheating, it may have the wrong coil or coil/resistor combination. If it's a 6v system, should have 1.5 ohms resistance across the primary terminals, out of circuit. For 12v, 3 ohms for a coil that does not need a resistor, or 3 ohms including the resistor.
Check the distributor shaft for side play. It needs to have very little wear. If the points are not staying set, the coil can overheat and the points will have shortened life, timing will be unstable.
