I have a Raby dyno'd 2270 that I have recently installed in my going on 4 year '74 restoration. It has a Mallory Unilite distributor and Mallory Promaster E series coil with ballast resistor. I can't get a spark at the plug or out of the coil. I have checked posts here and across the internet to no avail which means I'm missing something simple.
I have checked that the coil is not shorted and has proper primary and secondary resistence. The coil is getting 12 v on the '15' and '1' side with ignition in 'on' and in cranking mode. Although the voltage drops to about 10V when cranking. The tach lead is connected to the '1' side of the coil. The ballast resistor is in series with the +12 v connection from the ignition to the distributor. The coil is mounted to the engine tin on the passenger side near the oil cooler. I have checked that the distributor "points" are opening and closing. Can anyone see the simple item I have missed? Denis |

sounds like your points are burnt. If this is true, you'll need a new set. For a temp repair, and will not last long, remove the points and file lightly the point surface. Reinstall and try again. If this works, order a couple extra sets of points.

(IMG:style_emoticons/default/confused24.gif) He used points in quotes. Upon review, he did say he confirmed the operation of the sensor, so looks like a coil. If you have a Bosch blue coil, it should work without the resister. Carlos |
