Alright, i replaced the starter today. Now when i go to connect the battery the engine tries to crank over! With the ignition off? WTF!!!!

You missed a wire or connected one to something wrong. I did the same thing one time. Go back and double check connections.

DFlintstone

Double check that you connected the cable to the outer post on the starter solonoid, not the other that is nearer the starter.

Or hit it with a hammer. (seriously)

Or you got a faulty starter.

Or your Pos cable is touching the small green solonoid wire or it's terminal.

I think the first one was my issue when it happened to me.

You put the big red cable on the wrong side of the solenoid on the starter so its bypassing the solenoid

Hi Guys,

I was just out looking at this with OP_Rover.

All connections appear to be correct

There are only two wires.

One is a clip, and that clips into the female side of the clip.

The other one is an square eyelet that is connected to the outer most terminal.
The plastic tabs on the starter only allow it to be aligned and hooked one one way.

Both of these connections are on correctly.


When we hook up the battery, the Jeep tries to start with nothing in the ignition.


Any more insite?

Tks
Will

I think it's right...

Make sure the connections are the way that the old one was setup. Disconnect the small wire with the plug and connect the battery. If it cranks still the starter solenoid is stuck closed (or its still hooked up wrong. Hard to say without seeing it) if it doesn't crank with the little wire not connected then the s terminal is getting power when it shouldn't. Such as a bad IGN switch or a short to power on that wire.

zfranklin92

And yes that's hooked up correctly

OP_Rover

Thanks everyone. Zfranklin92, tried disconnecting the plug, it didn't crank. So I have an electrical short? Or something? Does anyone know how I move on from here? Electrical problems are not good for me or the people I wrench with to have. So y'all's help would be great

Okay. Why was the starter replaced? Like how did it fail? The little wire is the control side of the starter. It controls that solenoid. When the small wire has power it closes the starter solenoid and power comes from the battery, through the solenoid, and drives the starter simply put. The little wire gets power from the battery to the IGN switch to the neutral safety switch to the starter solenoid.

A simple test to see if its a switch problem or short to power is find the IGN switch fuse and remove it. Connect the battery. If the starter still cranks then you have a short to power. Most likely from the big red cable at the starter to the little wire(rubbed through). If it doesn't then you have a switch failure. Let me know what happens when you do that test and we'll go from there

You need to find the starter motor relay. I'm not familiar with yours. I would start by swapping in another relay....I'll look.....

Good catch Franklin. I thought of that but figured it wasn't very likely.

Willfulone

It failed like the battery was bad. It started turning over slower and slower
for the last few weeks and then it wouldn't turn over this morning.

We had the battery checked and it was fine. The alternator is fine as well.

Kind of like it gradually lost power until it died.

Alright, will do. I'm done for the night, I ran over my glasses with the creeper somehow and it's about 36 degrees out... Ill get after it tomorrow after school. Ill post up around 4ish, and we can go from there.

Starter relay should be in PDC...like D mentioned, swap it with another relay in there ( A/C clutch for example) to see if that improves things.
