Dead Battery or ?

My ol' CJ won't start. When the key is turned it sounds like the starter just clicks repeatedly. The voltage meter reads low and the lights have power but are dim. I tried jumping it off another car but it was difficult to get a connection on their positive terminal because only a small nut was exposed (the battery was squirreled away under a sheild) so I am not sure if I got power. The voltage meter did not change when they were hooked up -should it? I am wondering if there could be an additional problem to a low battery?

Re: Dead Battery or ?

Sounds like the starter solenoid to me.

Take a multimeter and hook it up to the battery and see if it is supplying enough power.

Re: Dead Battery or ?

1 starter just clicks repeatedly
Are you sure this isn't the starter relay, not the starter itself?
2. voltage meter reads low and the lights have power but are dim.
This means one of two things:
a. The battery is discharged, for what ever reason.
b. Clean the terminals, battery cable connectors, and all the 3 Grounds.
3. it was difficult to get a connection on their positive terminal because only a small nut was exposed
a. Remove the shield.
b. Charge the battery.
c. Remove the battery and have it tested.
4. The voltage meter did not change when they were hooked up -should it?
a. Uh...you're talking about the one on the dash, or a Voltmeter you're using to find problems?

Re: Dead Battery or ?

Why, I mean the crappy in-dash voltage gauge of course. What else would an idiot like me be relying on? Seriously though I do not own any of those fancy electrical testers, plus I ain't got need for no book learnin'.

The battery is definitely low for some reason. It is getting on in age -perhaps five years but is a good Optima which has served me well. Now, the starter relay and solenoid are the same, -the thingy on the fender, no? So that is the thing that makes the clicking sounds? And if the battery is charged and tested with clean terminals then that is the likely suspect?

Thanks fellas!

1. The starter solenoid is on the passenger side fender of the Jeep.
2. The key provides voltage to the starter solenoid.
3. The solenoid closes and attempts to provice voltage to the starter.
4. The starter pulls all the current the battery is able to give.
5. There's not enough current left to hold the starter solenoid engaged.
6. The starter solenoid drops out.
7. The keys still attempting to provide start the Jeep.
8. The current now is not being drawn by the starter.
9. The starter relay engages again...
10. The cycle repeats.
11. If the battery is charged.
12. If the cables and terminals are cleaned.
13. And the Jeep dosen't start.
14. It still could be the grounds.
15. Make sure the grounds are good (do this once every 6 months.)
16. You can pull the starter and have it checked on a Growler.
17. If the starter's bad you have three choices:
a. Rebuild it with a kit.
b. Buy a rebuilt starter.
c. Buy a new starter.
18. Confirm your parts are bad before you buy new ones!

Re: Dead Battery or ?

I succesfully jumped it and charged the battery and had it tested okay. The alternator belt had been slipping a bit on acceleration and could not be tightened anymore so has been replaced with a new shorter one. The 30 amp alternator outputs 25.6. Is the rating based on idle? If that output is lower than normal is it crucial to replace it? So the charging system possibly contributed to the dead battery and hopefully that was the only problem. I suppose I will not know until it has sat unused for a few days.

Re: Dead Battery or ?

Your belt was loose. The altenator slipped and could not produce the output needed to keep up with your demand. The slack in your belt determined how long your battery's life was extended/shortened (more slack quicker-less slack slower) With a loose belt it's like being in the Titanic ..the only question is how fast you sink.

Re: Dead Battery or ?

The lesson to be learned is don't ignore problems since I did hear the belt squeal occasionally.

It seems fine now. I really appreciate y'all's help. Me happy [img]images/graemlins/grin.gif[/img]
