That version uses a ballast resistor which drops the voltage in run. Check the voltage at the positive of the coil when in run. should be about 8v. Possible culprits are the resistor or the start switch or the electronic control box. You can switch to a pertronix unit and eliminate the electronics box and the ballast resistor.

I had the same problem. I switched to Pertronix dist. and its fixed. I can finally relax idleing through the busy channel and docking. :D

Also check the ballast resistor, they can fail and have the same symptom. My money is on either the control box or the ballast resistor, both of which are common failure items on cars as well as boats.

There are a lot of control boxes out there for Chrysler engines, with prices from below $20 to well over $100. I went with a car version from Napa for my spare, along with a ballast resistor. As far as I can tell it is identical to the Sierra marine version.

I have switched to a Mallory on the starboard engine and to a pertronix on the port engine. I have some spare parts left over for the Chrysler dizzy. If you want to keep the Chrysler PM me and I will let you know what I have.
