Chrysler Magnapower 75 HP Ignition

[dirtdoctor]

Model # 757H8D 1979 Year / I'm getting juice to the power pack but Im not getting any spark @ the plugs. Got 12v @ blue wire @ distributor / Got 12v @ blue wire going to power pack but not getting anything out of coil white wire with stripe. So I thought is was the power pack. Bought new CDI # 115-3301 Ignition box with coil installed it still no spark @ plugs . Put test light on white w/stripe while turning it over no light? Distributor has no points. What do you think I should check next? It was running fine one day then would not start the next day.

Sounds like the preamp is bad. Proper way to check is to remove the white/bl wire from the distributor, then connect a dvm with the positive lead to the blue wire post, negative lead to the white wire post. As you turn the distributor by hand, you should be able to read 12 volts and 0 volts as the rotor blocks and unblocks the sensor.

If it has a neutral saftey switch, try jumpering it.
