Starter troubles

Hey Guys,
I'm having a bit of trouble with my starter, it's brand new, so is the solenoid, and the battery is fairly new. The problem I'm running into is that the thing won't crank at all. It doesn't even make any noise. As far as I know it's all wired up correctly and the ignition switch is working. If I get the Jeep push started it runs fine, just won't crank over on it's own. Any ideas?

Gus

Re: Starter troubles

I'd pull out a voltmeter and test everything along the path of electricity. I'd make sure you're getting power to the input of the solenoid. Then I'd make sure its coming out. If it is coming out then I'd make sure the starter is getting good contact with the block, and that the block is grounded well.

I'd also check the wiring to the solenoid from the ignition switch. Pull out your wiring diagram and work from that.

If everything is getting power then I'd pull the starter, take it to Autozone and have it tested. I'd also check all of your grounds to ensure they are good. If you're not getting a good ground from your battery, to the block, to the frame then you're gonna have problems.

Re: Starter troubles

Thanks for the tips, I've already checked the starter, for the most part all the connections are good, there is one I'm going to redo, and I'll hope and pray that's the problem, if not it'll be time to tear apart the steering column and dig into those wires. Thanks for the time. If anyone has anymore ideas, please post them.

Re: Starter troubles

Hey Guys,
I'm still having troubles, so far I've replaced several solenoids to make sure that wasn't the problem. I've replaced the ignition switch, the starter works, I can put power straight to it off the battery and crank it over to start the Jeep, I just can't get it to crank over using the key and solenoid. I've measured the control wires going to the solenoid coil and I've got about 4-6 volts, could this be the trouble? Also any chance it could be the spark coil? I only measure about 4-6 volts there too. When I measure on the output of the solenoid, I don't get any voltage reading. And when I checked with an ohm meter, it shows that the output side of the solenoid is going straight to ground somehow. I pulled that wire out of the harness and checked it, it's clean, no cuts or nicks, but when I connect it from the solenoid to the starter it reads it going straight to ground, could this be that it's just reading right through the starter motor to ground? Any help would be greatly appreciated, it's a bit of a pain to get the jumper cables out and jump start the starter from the battery every morning. Thanks for the help guys.

Gus

Re: Starter troubles

If you put it in neutral, turn the key on and jump the starter solenoid (Battery + to "s" terminal one of the small wires) does it turn over then? *note* If it starts you have to remove the wire or the starter will stay engaged

If it does there is a problem:
1. with the wire
2. a bad ign switch
3. bad feed to switch

You should get full battery voltage to the "s" term on the starter solenoid with the key in the start position.

You also want to make sure that the solenoid is grounded properly.
