ok I have a 4.9L inline 6 fullsize bronco 1989 I have had trouble with my starter I just replaced my starter, starter cylinode, ignition module, starter switch and my lock and key cylinders and when i start the truck the starter still runs. is it possable that I crossed the line at the cylinode cousiing it to still have power in the run positon? any help would be great i am runing out of options please help

 

The starter relay (sometimes referred to as the ignition solenoid) on the passenger inner fender near the battery has a multitude of wires running to it. There are three terminals for wires to terminate. One little terminal and two big terminals. The little terminal should ONLY have the RED/LT. BLUE wire attached to it. One of the big terminals (does not matter which one) should have the heavy RED wire from the battery positive post AND ALL of the little wires with fusible links in them. The other big terminal should ONLY have the heavy RED wire that runs down to the starter motor.

Leave the battery connected and disconnect the RED/LT. BLUE wire from the small terminal. With the key OFF run a jumper wire from the battery positive post to the small terminal where the RED/LT. BLUE wire had been. Be careful, if things are working, the engine will crank when you do. (With the key OFF however, it won't turn over.) If the engine cranks when you touch the small terminal with the jumper wire AND stops cranking when you pull your jumper wire away, then you know the relay is working properly and the problem is somewhere else. If the engine continues to crank after removing the jumper wire, the relay is not disengaging and should be replaced.

This start relay is the ONLY location where power can get to the starter motor from the battery. If the engine/starter responds properly to the test above, put a test light or a meter between the RED/LT. BLUE wire and the negative post on the battery. Have someone turn the key to the start position. (Don't worry, the starter motor/engine won't respond because the power isn't getting to the start relay.) With the key held in the START position, the test light should come on or the meter should show between 11.5 and 13.5 volts. The light should go out or the meter should drop to zero immediately once the key is released. If not, the return spring mechanism on the ignition switch is not pulling the ignition switch back from the start position when the key is released. Most often when this happens, the problem is NOT electrical but rather mechanical and the keyswitch and mechanism components inside the steering column need cleaning/lubrication. Since you said the ignition switch itself has been replaced recently, I would suspect this to be the problem before I would suspect a faulty ignition switch. However, if the mechanism has been made to function properly and the problem persists, the switch may be defective.

I know thats a lot of reading but I tried to cover all the possibilities. I'd check things in the order I mentioned them. Good luck. Let us know what you find.

 

thanks that gives me tons to check I will salso check to make sure i put the ignishion switch in properly. I love when I get great answers from smart guys thanks!!

 

ok checked the solenoid works just fine repositioned the ignition switch in the right place and I am still geting continuous power to the starter

when I ran your second test I recived no light from my tester just so i understand the second test I pull the red/light blue wire from the solenoid attach my tester light to the neg battery cable and to the red/light blue wire at the same time have some one turn the key to start if the witch is working then I should see a light and then it should go out when key is released. well I saw no light. I have read on here that I could put a switch in that I just push to start the truck would that be easer? at this point I am going crazzy

 

On the second test was it in Park or Neutral if automatic tranny?

 

its a manual tranny so some one has to push in the clutch and I have a gray ignition switch

 

I had the same problem.(starter keeps running) It was my brand new solenoid. I turned my solenoid post on the starter side a quarter turn (out) at the second nut and it solved the problem. :u)

 

i not quite shure what you are saying that I should just turn my solenoid and reinstal to fender wall?

 

o also i dont have accessories when the key cylinder is in accessorie i sure it is linked to the switch?

 

The solenoid has two posts;each post has two nuts, the closest nut to the one nut is use to secure the wires, the other nut (closest to the solenoid) is used to position the post. It is not recommended but if your starter is continuously running it (the post) needs to be backed away from the inside winding so the metal plate that connects the posts can fall back when the key is not in the start mode. :u)

 

thanks guys I had a bad starter right out of the box t5he broncos running good now thanks
