replaced starter batter and alternator

i just got this jeep for $2000. now i knew i would have problems and it just now started to crap out. first time something happened was when i was about to go to work in the morning, cold morning, not frozen but cold. i went out to the jeep and turned the key, all the lights came on and since its new, i look at the gauges, all look good, about 12 volts on batter. CLICK CLICK CLICK really loud, nothing happens.

so i take out the battery, take it to autozone, it has cranking power, but he said it was kinda short, so i got the biggest replacement duralast. put it in the jeep. CLICK CLICK CLICK loudly again, nothing happens to the engine that i can here.

so i think, its GOT to be the starter. i take it out, its the original starter with 181k on it, so no biggie, it needs replaced. take it to napa cause i prefer the stuff they have, and got the biggest bestest starter, put it in. jeep starts. i drive it around all day, stop and start it 8 to 10 times. then i take a drive 40 miles south to pick up free firewood. stop down there, realize the radiator has a hole and is squirting fluid (i have a new one but i cant replace till i get my jeep back home!!). it starts, i drive it home another 40 miles, go to drop the trailer, stop the jeep so i dont get rolled on, drop trailer, get in jeep. CLICK CLICK CLICK.

get my toolls outta the back, take the alternator off, take it to autozone, ask them to test it, he tries, cant, so i buy a new one. install it. CLICK CLICK CLICK. so now im frustrated, i but all that in, tried to jump my jeep with sisters car, to no avail, my jeeps being stupid, i rocked it around, i have no clue whats up. any thoughts?

where is the click comming from? is it the starter clicking or something else? this really sounds like a relay problem or an ignition switch to me.

I agree...I think you may be one step closer to your answer once you trace down the source of the click. And it does sound like a relay or something.

I know this is extremely different, but might give you an idea...

I was putting fuel stabilizer in all our engines at work the other day and when I went to fire up my buddy's four-wheeler, I hooked up the jumper cables to the battery (battery is beyond dead), hit the starter and all I got was CLICK CLICK CLICK CLICK BUZZZZZZZZZ BUZZZZZZZ CLICK CLICK! There's a relay under there that was making all of those noises and not the starter. Now yes, that's a four-wheeler...but point is...make sure that you're not hearing a relay making all those noises. Also, something you may try...with the four-wheeler, if I repeatedly pressed and released the starter, every couple of tries, it would engage the starter. Once the starter engaged the relay stopping making the noise.

Just a thought...

also sounds like it could be the crank shaft position sensor (CPS). My YJ would have the same problem you describe. Most days it would work but then there were days it would just click. I had to push start it till I got around to replacing the CPS.

well i wasnt the one looking, a friend of mine said it was the starter, he was watching, clicking. i think the CPS sounds about right, i think the flywheel might be missing teeth or something cause it shifts all weird too.

what year is this thing? what trans, motor? need info. my next step would be seeing if it will start with a screw driver at the starter. if it doesnt start then you have a short in the wire going from the starter to the battery or your battery terminals are loose/dirty or just plain worn out or you have a bad ground. if it does start its a relay/electrical problem somewhere else in the jeep, check the starter relay in the fuse box. if it does start with a screw driver and all else fails id probably just wire a start button, momentary button wired to a relay sending power from battery to signal wire on solenoid, and call it a day.

It's not the CPS, guaranteed.

Clicking like that is usually caused by one of two problems. First is usually the battery but you've replaced that. The second is simply bad connections at the battery. I know you reinstalled the connectors when you installed the battery but are the connectors either so worn that they don't fit around the battery posts tightly any more, or are they corroded inside? I would wire brush the inside of the connectors until the lead is bright and shiny. Then when reinstalling them, I would attampt to turn/move them once they are bolted into place. If a connector moves on the post, it's worn and you need to trim some of the lead away from inside the connector's gap so it can close tighter around the battery post.

Finally... turn the headlights on while you try to start the engine and watch the headlights as the starter clicks. If the headlights dim or turn off, that's a good sign the connectors are bad since you have already replaced the battery.

^x2.

I had a similar problem turned out to be the ignition wire. The previous owner put a security system in, then decided to rip it out not knowing it was tied into the ignition system.

By the description it sounds like a bad battery connection - like Jerry said.

You haven't answered the question if it will crank when you put (+) 12 volts on the small wire on the solenoid. Try it and report back here.

Jeep doesn't use a separate starter relay, the click is the starter solenoid.

Check the bolt where the (-) cable attaches to the engine block. Loosen, then tighten.

If that doesn't help, make it click several times by trying to start it, then feel along the battery cables for a hot or warm spot - BOTH CABLES. If you find a warm cable it indicates a resistance in the cable - replace it.

The CPS has nothing to do with cranking the starter.

The way that the parts house tested the starter - making it spin unloaded is not a valid test. Even if it was very bad it will spin without a load.

It's a dc system. As long as you don't touch the terminals together your fine. a wire brush is the best way to clean them. Iv never had a battery hurt me even if I touch both terminals. The ignition system on the other hand can make your arm jump if you get hit with the spark but won't really do anything to you. Even if you do manage to touch the battery terminals together with a wrench it really just makes a bunch or sparks and scares you, and leaves a nice burn mark on your wrench.

Just run down to your local auto parts store and buy a battery brush. It pulls apart into a male and female wire brush which is ideal for cleaning both the battery posts and connectors.

Try touching both the battery's - and + terminals at the same time with your fingers and you'll learn that 12 volts won't shock you. In fact, you won't even be able to feel anything.
