Bronco wont turn off

[swimsy]

I got home turned my key to the off position and took the key out and nothing happened, the bronco stayed on. I tried repeatedly turning it on and off, and it would not turn off. Is this simply the ignition cylinder gone bad or could it be worse. Any help to a non mechanic would be appreciated

This seems to be happening a lot lately. Here's what I did in order.

Replaced lock cylinder--No difference ?:?
Replaced starter solenoid--no difference (All wires in the right place I believe) ?:?
Replaced ignition switch in the dash--No difference ?:?
Pulled starter and had it checked--Checked fine ?:?
Jiggled the voltage regulator plug--Fixed it--for about a day
Replaced voltage regulator--Fixed it-- for about a week until about 2 hours ago it did it again.

From what others have told me, the only thing left is a new wiring harness.

Anyone else care to chime in. I'l be watching this post as well...

mustangmarty you are making me nervous, I thought that this was simply a bad ignition cylinder and would be a quick and easy fix. I will be replacing that tomorrow and I hope it will solve my problems.

Hopefully you get lucky and fix it right off. Let us know what happens. Mine is running fine again today. All I did was unplug the voltage regulator and plugged it back in. I don't see how a voltage regulator could have anything to do with it, but I'm going to oarts store for bottle of contact cleaner to clean out the plug contacts anyway. Can't hurt.

I agree,The ignition cylinder is the culprit.

Pull the Brown wire off of the starter solenoid on the fender.

After all that, it turned out to be a defective solenoid that I got from the parts store. How did yours turn out Swimsy?

Heh, most of us have problems with the truck not turning ON.

Had the same problem with a Bronco II a few years, back, was the solenoid.

The bronco just wants to go more;D Probably the solenoid also
