"I have installed a Mallory Ma

"I have installed a Mallory Magnetic Breakerless Distributor on a 318.
The mallory wirirng diagrams indicate a ballast resistor is required but they do not show the resistor being bypassed during the start cycle.
Engine is hard starting but runs fine when wired per the Mallory wiring Diagrams.
Anybody have any suggestions?
Thanks,

"Joe,

If you don't get

"Joe,

If you don't get a response here you could call the tech support line at Mallory: 216.658.6438"
 
Hey Joe
The ballast resistor

Hey Joe
The ballast resistor has to do with the coil. If it's a 12 volt coil you don't use the resistor.
Usually the coil is imprinted with something like "USE WITH EXTERNAL RESISTOR" or something to that effect.
 
"Conqueror, What ignition coil

"Conqueror, What ignition coil do you have?

Joseph J Levelis, What ignition coil do you have?"

"Thanks for the comments but:
1- Mallory Tech support does not answer just voice mail. I will send them an email.
2- The coils I have tried are 12 volts, all requiring an external resistor.
3- The mallory installation instructions state:
"The purpose of the ballast resistor is to limit current flow through the coil, failure to use a ballast resistor will eventually destroy the ignition module.""

I'm sure that the Mallory statement was to be interrupted, failure to use a ballast resistor in continuous use will eventually destroy the ignition module.

The 12 volt coils of old had more windings in them (more resistance) than the 12 volt / EXTERNAL RESISTOR coils.

I suspect that statement means

I suspect that statement means use of a 9 volt coil without a ballast resistor. Lots of replacement ignition modules out there running 12 volt coils and no ballast resistor.
