Random dying -solved!

We speak in these forums a lot about random ignition problems that keep our trucks from running well, and the culprit is often the ignition module.

Recently, Lady Chatterley had been acting up. Over several days, I'd be driving along, and the engine would die, but just for a moment. It happened so quickly that before I could take a bearing, it was running again. If I was stopped, for a red light perhaps, it might actually die, but I could restart it without problem. This has happened with the other trucks, but generally when it was hot out.

One particular night, nearing home, it twice hiccuped going up the hill to the mesa. I didn't trust it to make the left turn across traffic, especially if I missed the light. So I hung on the right shoulder, and hoped to make it to the gas station. As we crested the hill, the truck died again, but I was able to coast into the gas station.

After a few minutes, I tried starting the truck. It started right up, but only ran for about thirty seconds. Knowing there was no future in this, I callled for a tow.

When the weekend came, I pulled the stator out of the distributor (i keep a spare in the toolbox). The magnet(?) in the base of the stator was cracked and apparently broken. Unfortunately, i broke the armature while removing it. Today I replaced the armature and stator, and Lady Chatterly rides again!



Busted a tooth off the armature during removal


Your crack is showing!


Busted clean through...

What would guess the age of the armature and stator to be?

Lady Chatterly is a 78, and the parts appear to be OEM, so I’d guess 43+ years

The stator, also called a pickup coil, is the first thing that should be replaced when your engine starts acting up, & you even suspect it is ignition.

Usually though, people replace the ignition box, coil, wires, plugs, cap, rotor, sometimes a couple of times each, before they do the stator.

This isn't just a Ford problem, I used to have to replace them in my Dodge, which had two of them under the distributor cap.

yep, I did that the first two times. Fortunately, by having three trucks, I could swap parts without buying them

By the third time, I went straight to the stator!
