Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello laurel.ellis, it sounds like you have a starter issue. The first thing we need to check is power to the starter. This will confirm or direct us on what we are dealing with. On the starter solenoid, there are 2 terminals. A large one and a small one. The large one is the battery lead to the starter, the small one is the lead that engages the starter. Using a test light or voltmeter, see if you have power at the small wire when you turn the ignition to crank. If you do, you have a bad starter. If you don't then we look to see where our command to crank the starter is being interrupted. Let me know what you find. If there is no power, I will get you a diagram and tell you where and what to check.
Your JA Expert,
It looks like there is no power going to the starter. Would you please send me the schmatics and explain how best to check the wiring.
ALSO, could you explain to us exactly where the starter is located in our 2000 Jeep Grand Cherokee so that we can be certain were looking at the starter and not something else?
Most certainly. Here is the location of the starter and a wiring diagram. The light green wire on the starter solenoid is the wire you are going to test. Make sure you use either a test light connected to ground or a voltmeter with the negative connected to ground. Re-verify power or no power and let me know, then I'll guide you to the relay and up the circuit as needed.---Ivan
Thank You, Ivan.
We are having a friend come over tomorrow to help with checking the wiring. We will get back to you then. Once, we don't have anymore questions we will be sure to click the accept button so you get paid.
You've got a deal. I'll be with you until it starts, so feel free to ask what you need to.
We have a friend coming over this weekend to help us. Would you please send us the instructions for replacing the starter motor just in case we need to?
It's actually pretting simple. Look at the location illustration I sent with the diagram. Disconnect the battery. Disconnect the 2 electrical wires that go to the starter. Then remove the two bolts indicated in that picture. The starter will come right out after that. Let me know if you have any problems.
Well... Here's where we stand. We found that there is power to the starter. We pulled it and found the solenoid may be sticking a little. Our friend cleaned the solenoid brushes and checked it out and then hooked it to his battery charger and it worked fine. When we put it back in the car, it's still having the same problem. It clicks once and that's it. We don't want to have to buy a new starter if that's not the problem.
Replace the starter. If your battery is strong, your starter is too weak to push the engine. It will spin when bench testing, but not enough torque to turn the engine. Just make sure your battery is good and postive and negative cables are clean on both end. Unbolt the ground cable from the engine block and clean the end and the bolt as well as the contact point. Make sure you have around 12 volts to the larger terminal on the starter during crank. If you do, use jumper cables to clamp the body of the starter to the frame. This will act like a secondary ground. If it still won't crank, put a starter in it. Tell me what voltages you find and if the battery is good. You can even try jump starting it and see what happens.
Thank You, XXXXX XXXXX'll let you know what we find.
Bad news.... We put in a new starter and the Jeep is still doing the same thing. Clicks once and that's it. We checked the ground wire and made sure there was 12 volts going to the starter before replacing it.
Any other ideas???
I will re-check all of the things you have suggested. I did have a friend come over with my husband and check things out with his volt meter. I will have back over tomorrow and go over it again.
My husband did try jumping it from our other jeep. Should this have worked even if the battery was bad?
I will have him take the battery down tomorrow and have it checked...
Finally, we have the car running. Thank you so very much for your expert help and staying with us through the whole process. The battery was fine, however there was a connection problem inside the battery wire where it connected to the terminal. Cleaned it up and cut it back to clean wire and it starts perfectly.
Too bad your not a Porsche mechanic we just sent our 2006 off on a flat bed. Do you believe it it's only 2 years old with 15K on it. When it rains it pours. At least this one is under warranty.
Thank you, again,
Hoooooraaayyyyy!!!! Your very welcome, I'm glad I could be a part of it. Look me up if you ever need anything.
