Not turning off

[shadowfax101]

I have a question. I tend to have a lot of these. My wagon will still not turn off and I have changed the alternator, the ignition switch, and the selonid. Can the coil go bad? If I unplug the batter or the alternator it will turn off. I have been looking for bare wires that would cause a ground. Any ideas about the coil and where I should look for a wire. I have an 85 grand wagoneer. Thanks for all your help.

One of the wires attached to your alternator is a resistor wire. If it is damaged, melted, broke, or disconnected from the back of the alternator, the engine will continue to run after the ignition is turned off.

So you are saying that the two wire running into the alternator needs to be checked. That one on them is bad. I quess tomorrow morning I will follow the wires and look for damage. Should I only be concerned with only the two wires from the alternator.

More info...

Ok my amp gauge is about 30...The gauges are not working, and it still will not turn off. I have changed the ignition switch, the selonoid, and the alternator. Do all the problems hinge on the alternator. I have put a brand new delco in two weeks ago. Do I need to change the voltage regulator.. I always thought it was in the alternator. Please help.

you need put a resistance like a bulb betwin the exitation terminal on the alternador and the ignition switch, when you turn on the switch the bulb turn on until the egine turn on, the bulb work like the "alt"light indicator sorry for my grammar but i'm still learning

good idea. That is what I was thinking about doing today as a matter of fact. I will try it tomorrow...

While the jeep is NOT running and the ignition switch is off try hooking a volt meter to the positive side of the coil and to the negative on the battery. You should have NO voltage.

If you have 12 or so volts than it is not your resister wire.

Some jeeps use the 'ford' type starter solinoid. There are two large posts and two small posts. The large posts are connected to the battery and the starter. The small posts are the switch and a 12v feed. The 'switch' side is on the same side as the post for the battery. If you apply 12 volts to this, the starter will turn over. (Your igintion switch does this) When the car starts, the power to this small post is cut.

AT THE SAME TIME the starter is turning over the engine, 12V is sent OUT of the other small post. This is often connected to the coil to give the coil 12v during starting only. 12v can help the coil at lower RPM but can cause trouble at higher RPM

If the wire that is normally connected to this other post is connected to a non switched source then your coil will always get power and your engine will keep running when you turn OFF the iginiton. (BTW, this is how you 'hot wire' your jeep) Locking steering/tranmission keep people from driving away but it works if you have the key and a bad ignition switch.


Hope this makes sense.

Thanks for all of your help. You people were right. I cut the resistor wire and I added some resistance and she works just fine. Even the amps when back down to normal. What a load off of my shoulders. smile.gif smile.gif :D
