I have a Wildcat with a 318 electronic ignition. The engine runs strong but occasionally stops and will start after several minutes.
It's not a fuel problem, it seems to be an electrical issue. Anybody have an idea what is going on? Thanks

Sounds like the coil is getting hot. You could wait till it does it again, and see if the coil is too hot to touch, or just replace it.

Sorry, not only check the temp of the coil, but check for spark as well.

I replaced the coil with no luck, has the same symptoms. Also I checked the spark after it stalled and there was no spark then after 15 minutes it fired right up.

Resistor? Does it have one, does it need one? Was the coil hot this time? Is the coil oil filled and laying on its side? Still sounds like a coil issue with no spark, but I'm not familiar with the Chrysler motors.

Not sure about the resistor, I will run it tomorrow and check the coil temp.
What your saying is if the resistor is bad this will cause the coil to heat up?
Ed, I apreciate your help. Thanks, Steve Todisco

No problem Steve. Also, did you replace the cap and rotor? Just a thought.

Not yet but will do it. I am also going to check the celenoid. During my researching of this problem, a failing celenoid was mentioned as a possible cause for the ignition to cut off.

Another thought Steve, Don asked about your ballast resistor. If you do have one still, make sure that it is bypassed.

I feel you are off in the wrong direction if you are referring to the starter relay (solenoid). It's only activated during engine cranking.

When you checked for spark, did you check at the coil or just one of the plug wires? Checking at the coil would isolate it being the problem.

Before you replaced the coil, exact same problem with the old coil? Sounds to me like an intermittant problem in the ignition module.

Just ordered a new ignition module. Thanks guys, hope this does it.

Be sure and check what coil the ignition module wants and if it needs a resistor or not. This is one of those areas where you get away from the original and it can get confusing and cost you a lot of parts and lost time trying to fix a simple issue. I remember going through these sort of things with the external voltage regulator and the electronic ignition on my first inboard, it was a real PITA going to the lake and wondering what was going to go wrong. Good news is once you get through the learning experience you know a lot more about your boat and it should be free from those problems for quite a while.

Is it normal for the coil to be extremely hot after running the engine for 20 minutes? , like 142degrees? Have not replaced the the ignition module yet.

NG,
I don't see any mention of you checking the voltage to the coil. Several suggestions have been made to find out if the ballast resistor is used for you EI conversion. Do check on that.

To me, that coil is running too hot. What did you replace it with?

No, a bad ballast resistor will not overheat the coil. The typical failure of the resistor is a open circuit so you would get no power through it.

Not sure where to look for the ballast resistor

Steve while all engines are different most electrical items
are relatively in the same areas. Here is a picture of mine,
the resistor is that white thing on the left side of the engine,
middle of picture held on by a aluminium bracket.

Kind of white porcelain rectangle with a thick coil of wire running through it, usually visible from the side.

That Steve is my 302 Holman Moody Ford that started life as a 289 but somewhere along the line has had the block replaced.

Gary, I am a bit confused with this resistor stuff.
Does a coil with an internal resistor need a ballast resistor?
If the coil does not have an internal resistor, is a ballast resistor nessesary? And what is the difference between the two?

[QUOTE=Yellowbird] Gary, I am a bit confused with this resistor stuff.

Does a coil with an internal resistor need a ballast resistor?
No it would not

If the coil does not have an internal resistor, is a ballast resistor nessesary?
Yes

And what is the difference between the two?
Coils can't run at the full 12 volts so the voltage needs to be reduced somehow.

You cannot go wrong with one like http://www.summitracing.com/parts/MSD-8222/" rel="nofollow - this one
it's epoxy filled so it can be mounted in any position and
you need http://www.summitracing.com/parts/MSD-8214/" rel="nofollow - this resistor to go with it.
You can tell if it is an oil filled coil by shaking it and they are not to be mounted on their side

Is there a wiring diagram anywhere for connecting an external resistor to a coil???
