took my boat out this morning for a fishing day. Ran out about 4 miles or so then throttled down for a troll and started laying lines. About 5 min into running at 800 rpm she dies. I quickly started her up again and she ran for another five before dying again and the she wouldnt start at all. Came in on my kicker and took her home.
When I got home gave her a bump and she fires. Hooked up the water, fired her up and while running started checking possiblilities.
checked for spark getting a weak looking spark so I man up and hold the plug. not much of a jolt, in fact no jolt really just some mild feeling. when i checked the coil connections i noticed the coil was blistering hot. Too hot to touch.
Recently I installed electronic ignition conversion (Mallory Unilite) and ratrher than do away with the ballast resistor I just hooked it up as it was on points.
It's been running fine until just now. Never seen a coil just go bad and I'm not sure why it's getting so hot.

Solution anyone?

Re: Coil problem?

You are going to have to wait for the experts on here, but the only coils that I have seen go bad, its just blam, they are bad, not weaking, so I wouldnt think its the coil, I think you have somthing hooked up wrong, coils shouldnt get to hot

I'd agree with "hooked up wrong" Cept it ran so well hooked up just like it is last time out and last season as well. I run 700 to 800 RPM for 5 to 6 six hours on an average troll .... very curious problem here...
