Continued electrical problems!! argh!! updated

Well I just cant seem to track this problem down. I try to start the jeep and the solenoid just clicks. Everything works but the jeep wont start.
List of things done:
-had battery tested and charged, tested good.
-replaced solenoid
-replaced battery cables with 2 gauge cables
-replaced the solenoid to starter cable with 2 gauge cable
-replaced the starter

Tested the battery before starting, 12.22 volts. After all this, nothing. Had to jump start the dang thing to get it to run.
While Idling I tested everything with the volt meter. Battery had 14 volts, alternator putting out 14.5 volts, 14 volts at the solenoid. Last time I jumped it, 3 hours later it wouldnt start. I'll try again in a few hours and see what happens.

Any suggestions? This is starting to piss me off!

Re: Continued electrical problems!! argh!!

The fact that it started with a Jump indicate the problem is with the battery dispite your tests. Borrow a battery from someone and swap it in and see if the problem goes away.
I'm sure you have cleaned your battery terminals and clamps but give them another look. I've also been fooled by corrosion where the battery cable connects to the clamp.

I cleaned everything. Not a spot of corrosion on any of the terminals, heck most of it is new. I had a similar problem about 1 year ago, bought a new battery and that solved everything. There has to be something causing the battery to drain, I cant replace a battery every year just to keep this thing alive.

Re: Continued electrical problems!! argh!!

You said you had the battery charged and tested, but it should have read at least 12.6 volts when fully charged. Lots of vehicles will not start at 12.2 v. Have the battery brouoght up to at least 12.6, then have a load test applied to the battery, most parts stores do it for free. The test consists of having a carbon pile load of half the cold cranking amps applied for 15 seconds, if the battery falls below 9.6 v, or doesn't bounce back up after the test is over, it's no good.
It has to be a pretty good 12.6 to start. Try that then tackle the power drain problem.

Re: Continued electrical problems!! argh!!

How was the battery tested? It needs to be load tested. I've seen a few batteries that will be at 12V, but will drop when a load is applied.

you could have a short. I had similar problems but I found the shorted wire, it was easy in my case because the wire that was shorting out was melted. there have been lots of posts on how to find shorts. most methods require removal circuit paths then testing for current draw. try a search.

Re: Continued electrical problems!! argh!!

I agree with MaxW82CJ7with one possible exception. If you connected the jumper ground cable directly to the engine, the problem could be in the battery ground to engine connections. Otherwise, go with what MaxW82CJ7said.

Re: Continued electrical problems!! argh!!

I had the battery load tested at the parts store and it came back good, that was when i thought it was dead a month ago.

Re: Continued electrical problems!! argh!!

You dont think your new solenoid is grounding out ? I`m not much at electrical systems but I had that on my old CJ years ago . Have you disconnected the battery overnight and see if it still does this ?

Re: Continued electrical problems!! argh!!

i would suspect a bad ground. when you jump it with another vehicle's battery, you are using the grounding system from the other vehicle as well. i would check all the grounds and make sure they are clean and tight. make sure the solenoid is snugged down tight as it needs to ground as well.

Re: Continued electrical problems!! argh!!

When you say jump started we are assuming with another vehicle/ battery not push starting .Right.
My manual says
1 check connections yada yada you have evidently done all this .hopefully ?
2 disconnect the wire at the solenoid S terminal
3 connect a jumper wire from the battery (+) to the solenoid S terminal if engine cranks Solenoid is not bad.Look for problems in the starter switch circuit.
4 If the engine does not crank connect another jumper wire from the battery
(-) terminal to the solenoid mount bracket.Ensure a good connection is made.If the solenoid now operates it was not properly grounded.
5 If the engine does not crank ,remove the jumpers and connect a heavy jumper cable between the battery and the starter motor terminal of the solenoid if the engine cranks solenoid is defective if the engine does not crank check the starter.

My own personal experiance with whis type problem was caused by an in dash Ampmeter. Took the jeep for a ride parked it went into the store came out it would not start .Replacd everything ,Had mechanics check everything for voltage and what not,everything was good. I can't recollect if I push started or Jumped it but it would start except with the key.Eventually I found that the wires on the ampmeter had come loose.and that was the problem.it now resides in my tool box.
Sorry to beat this dead horse again but thats my story and I'm sticking to it.
