Every light in my jeep wont work or will my jeep start. I have had the alternater tested and it passed. I also replaced the ground cable. I jumped my jeep and and disconnected the jumpers and it run fine for a short time then the lights go dim before quitting out and then the jeep just dies. So I guess my question is, besides the alternater and ground cable why are my lights not working or will my jeep start with out a jump?

Do you
have the same problem?

Jeep wont start. Lights don't work. Volts won't even register on my gauge. I just had my alternater tested and that was fine. Someone suggested maybe a bad ground wire. Replaced that. And I have a brand new optima red top battery. It won't start without a jump. And when the jumper cables are hookd up lights are bright and everythings good. As soon as I disconnect the cables the light start dimming down to nothing. Then jeep bogs down and dies. Could it be a bad silonoid?

Disregard the non-functioning link!

I went over there and got it, Copied, Pasted, and put the pics back in!

OK the 1st part was sorta for other applications, but you will see what I intended for a CJ. Ask me questions, CJ fixin' is my Crusade at this site! I will assist you on a more personal, "HOLD YOUR HAND THRU IT" level than some of the other fellers. See other CJ5 & 7 questions in the forums, you will see the extent I go to assist CJs!

CHECK YOUR FUSES!---YOUR OWNERS MANUAL MAY SHOW YOU LOCATIONS THAT YOU KNEW NOTHING ABOUT!

REMOVE AND REPLACE "SUSPECT" FUSES SEVERAL TIMES--THIS MAY SCRAPE OFF CORROSION AND GIVE THEM BETTER CONTACT!

THIS WILL WORK FOR YOU, PROVIDED THAT YOUR BATTERY IS GOOD---OR YOU CAN BE JUMPED OFF!

REMEMBER "NEW STUFF" CAN BE BAD TOO!

YOUR STARTER MAY BE BAD!

YOUR SOLENOID MAY BE BAD!

Try the stuff below (actions), Even if this isn't your system.

Yours may not look like this, but TAKE STUFF LOOSECLEANTIGHTEN WELLDO NOT JUST PASS IT OFF AS, "IT LOOKS GOOD".

Do not leave off where the Battery cables connect to the Battery clamps! (Not the posts, the "squeeze connections" on the wire) Do them too!

While you are at it, Both ends of Pos cable, Both ends of NEG cable.

If you still have the problem. Follow Battery Positive cable to find the Solenoid.

Clean and tighten the starter connection!

My stuff may be OVERKILL, but at least you will know what everything is and does.

Like my newly made "NELSOMATIC" stuff? I am cyber stupid, and did that! Keeps me from hunt and pecking so much!

Follow POS BATT CABLE, It will end up at MR. SOLENOID, yours may look different, but function is the same

Insure you are hooked up correctly and tight.

Make sure "S" WIRE is attached to the Solenoid

"OLD FORD TYPE" SOLENOID SYSTEM, YOUR ACCES, MAY VARY (This was really intended for Jeep CJ People!)

1) POSITIVE CABLE FROM BATTERY

2) OUT TO STARTER MOTOR

3) ON MY JEEP, THIS GOES TO THE ALTERNATOR

4) THIS FEEDS MY FUSEBOX (ALL OF MY ACCESSORIES)

5) "S" WIRE IS FROM KEY, 12V ONLY WHILE YOU ARE "CRANKING"

THIS WIRE ACTIVATES THE SOLINOID'S ELECTROMAGNET, WHICH IN TURN, CONNECTS---A and B INTERNALLY (ONLY THE 2 LARGE GAUGE CABLES CAN HANDLE THE AMPERAGE THE STARTER "PULLS").

WHEN THE SOLENOID IS ACTIVATED, IT THROWS 12V TO STARTER USING THE LARGE GAUGE CABLES (1) POS FROM BATT--THRU SOLINOID INTERNAL CONNECTION--(2) TO THE STARTER, WHILE KEY IS IN "CRANKING" MODE.

THIS IS THE TOTAL REASON FOR A SOLENOID, BECAUSE IT WOULD NOT BE PRACTICAL, TO RUN THE HEAVY CABLES TO AND FROM YOUR KEY SWITCH.

6)"I" WIRE (OPTIONAL), FEEDS COIL "FULL 12V", ONLY WHILE "CRANKING", AFTER YOU RELEASE THE KEY, THE COIL REVERTS BACK TO REDUCED VOLTAGE, SUPPLIED BY YOUR KEY IN THE "RUN" POSITION.

7) "SOLENOID MOUNT" GROUND, UNIT MUST HAVE A GOOD GROUND (BATT. TO ENGINE, ENGINE TO FRAME, FRAME TO BODY [ALL MUST CONNECT, SOMEHOW] )

(3 and 4, ON MY JEEP) ARE FUSABLE LINKS, ALL ARE NOT MARKED, MY #3 IS, #4 IS NOT. ITS SORT OF A "WIRE" FUSE.

IF THEY ARE GOOD, TUGGING ON THEM WILL BE JUST LIKE A WIRE, WHEN THEY ARE "BURNED UP", THEY WILL STRETCH OUT LKE A RUBBER BAND.

If your SOLENOID is good---Just not getting a "Signal" from the Key--We can test that too! (Then you will know which direction to chase this problem)

"S" is the wire that activates the Solenoid----we can sorta cheat it!

Regardless what you do to cheat it, You are suppling 12 VOLTS to the "S"('s) terminal on the solenoid. This is momentary as if you are cranking with the key

STAY CLEAR OF MOVING PARTS!IN PARK--OR EMERGENCY BRAKE ON!

I prefer a "Remote Starter Switch"

A Jumper wire momentarily touched or a Screwdriver touching POS BATTERY or POS BATTERY CABLE to the "S" terminal will by-pass the wire from the key

This will for sure let you know whether its a Solenoid problem or a Key ( ignition switch not delivering 12 Volts)

This will start your rig if your key is in the "ON" Position

IF YOU HAVE A CJ 5 OR CJ 7---YOUR WIRES SHOULD BE HOOKED UP, EXACTLY AS MINE ARE, IN THE PICS!

JEEP CJ GUYS!--If you changed your coil and did not get the one that says, "FOR USE WITH EXTERNAL RESISTOR ONLY". You NEED TO GET THAT ONE! You have just "DOUBLED" your resistance (w/ one with a internal resistor), and DO NOT HAVE ENOUGH VOLTS TO MAKE IT FIRE! (Your resistor is a "RESISTANCE WIRE" going to the coil already!)

Please Reply, Good or Bad

Make Absolutely Sure, that NEGATIVE ON YOUR BATTERY IS ON GROUND!---POSITIVE IS ON SOLENOID!They do swap sides on the Battery with POS and NEG, for other vehicle applications. SO ACTUALLY EYEBALL THE SYMBOLS!

Hook up your stuff exactly in my pics above!

Even a New Battery may be dead or bad!

Is it turning over when jumped?

I'll be around another Hour or so, Eastern Zombie Time is fast approaching!

Not Solenoid Itself---May be loose Corroded Connections on it. Or incorrectly connected. If the Jeep starts when Jumped.

All of your accessories, bolt onto the same side of solenoid, so they are connected permanently.A non working solenoid will not start your Jeep, but all accessories should work.

I cannot stress enough, make sure your battery is not hooked up backwards!

Keep info coming---anything, that you may not think is important, recent history. Evil Buddy Factor, etc---Detail is my FRIEND!

Ya once the battery gets enough charge from the jump it will fire up. But once it gets disconnected. The lights ( dash and head lights) dim immediately and volts drop right to nothing and then with in a minute maybe two the jeep starts "burping " then just dies.

It's rare I'm on with someone at the same time, so I saw your postings after I continued on.

It's gonna be something stupid!---So do what it says about taking everything in question loose, clean then tighten well!NO CHEATING, BY SAYING, "IT LOOKS GOOD". It very well could be your ground wire Battery to Engine, or the clamps that squeeze the wire onto the Terminal clamp, Sometimes I remove the Squeezer and Turn it over, to really bear down on the wire really tight.

See you in the morning!

Look over your alternator, is everything plugged in?

IF YOU WILL JUMP FOR 20 MINUTES OR SO, BEFORE YOU CRANK AND REMOVE THE JUMPER CABLES. IT MAY CHARGE ENOUGH TO PERFORM VOLTAGE TESTING

Test for about 13.5 OR MORE volts while running (ALTERNATOR WOULD BE CHARGING FOR SURE). ABOUT 12VOLTS IF NOT CHARGING, AROUND 12 Volts not running, at the Battery POS and NEG Posts. YOU CANNOT TEST THIS WHILE STILL HOOKED UP WITH JUMPER CABLES. YOU WOULD BE TESTING THE OTHER VEHICLE!

Check your wiring further down from the alternator.

Is anything accidentally touching the alternator?

DID YOU LET WIRES HIT GROUND AND SPARK, WHEN YOU REMOVED THE ALTERNATOR?

DID YOU MAYBE OVER-TIGHTEN WIRES ON REAR OF ALTERNATOR, AND SPIN THE STUD AND POSSIBLY BREAK THE INTERNAL CONNECTION?

REMEMBER, YOU HAVE THE OPTION OF BLAMING YOUR EVIL BUDDY.

BSing DOES NOTHING TO ME, MINE RUNS FINE! YOU MAY JUST BE BSing YOURSELF.I'M HERE TO HELP YOU, NOT CHASE THINGS THAT ARE REALLY NOT WRONG. IF YOU SUSPECT THIS, AUTOZONE AND ADVANCE AUTO WILL TEST YOUR ALTERNATOR FOR FREE!

SORRY, BEEN THAT ROUTE BEFORE, CAUSE SOMEBODY GOT SKEEEERD, I WAS CHASING GHOSTS FOR A WHILE!

We will test further, after you go thru all other steps THROUGHOUT THE POST!

I just got a shot of mine, maybe it will help.

The medic,

I tried it all followed all the wires and cleaned everything and double checks the tightness.

When the jumpers are hooked up the volts obviously read around 13.0. As soon as I disconnect the jumpers come off the volts drop right down to nothing. And the light dim right to nothing as well. But the jeep is still idoling Fine fore a few minutes before bogging down. But with no volts reading on guage.

Like I said I had my alternater tested and it passed.

How would I test my battery to see if that's it?

And after I turned my jeep of after the jump. I put my key in the crank position, and pulled the lights on and they go on for a sec. Before dimming down to nothing. But then I tried to turn it over and the starter was cranked but not enough juice to fire up.

Can't wait to figure this **** out!

My jeep is my baby. I use her as my everyday driver (well I used to use it everyday).

Roger,

I think you have 2 issues going---Battery and Alternator

Battery may be dead--Take to Autozone or Advance Auto or other, they will maybe keep it to charge and LOAD TEST IT. Do this, it's important!

Who tested the alternator. How do you know for sure it's good?

It may have a "HOOK UP" issue gone wrong, even if it's working right (we will attempt to check that. AFTER YOU GET IT RE-TESTED at the parts store for FREE!).

3 Ways to test it. Require a little work on your end!

I would help you, FOR FREE, if you will swing it by here!

1) Jeep "off" voltage, at battery terminals is about 12Volts Normally---Crank up and running it will be 13.5 or better if the alternator is charging. (Both readings at battery posts)

2) Drive it to parts store for tests (Free). Probably hard to get it there!

3) Take it off your baby, take it to them for the test.I suggest this, before we start guessing at stuff, that may be the alternator being the whole problem.

What should be happening, even with a really weak battery. The alternator should be running the show well, even if the Battery ain't helping out.

There are only a few wires to look at for problems, if you tell me that the parts store Just re-tested the alternator and it DOES WORK on their machine. Please do this, before we look for other problems, that may not exist!

I've owned 7 CJs, all primary drivers. Got my 1st in 1981.'77 CJ 5 304. My present is a '77 CJ 5 258 and a 1946 Willys.

I hate driving other Vehicles----I love looking out over my Jeep Hoods, It's Just A "GIVEN" and it's Natural!

Any more problem history or repairs or events leading to this may help me. Spill your guts, even if something stupid happened. Consider this your Jeep Confessional.I will not think any lower of you!

This is my Hobby, I have been doing this for the last 2 years while my foot w/ complications mended. If you investigate the "5" and "7" Forums, I have been the Primary Responder, during that period.

I am here to help you thru all of this-I know CJ's really well, I built my last 2 from almost the ground up. Solo!

Do you know how to use a VOLTMETER?

HOW 'BOUT AN UPDATE--BEEN WORRIED ABOUT YOU!

GIVE ME SOME RECENT HISTORY, PRIOR TO THIS ISSUE. ELECTRIC HOOK-UPS, 4X4ing, ETC. MEGA DETAIL IS GOOD!

STILL WANT TO HELP IF I CAN, HOPE I HAVE NOT GOT YOU MAD AT ME!

I WILL TRY TO GIVE YOU FIGURES FROM MY ALTERNATOR AT CONNECTIONS, "NOT RUNNING" AND "RUNNING" ON THE VEHICLE, SO THAT WE MIGHT KNOW WHAT TO TRACK DOWN.

I FEEL YOUR ALTERNATOR IS NOT CHARGING AND KEEPING YOU RUNNING---OR---SOMETHING IS NOT ALLOWING IT TO CHARGE THE BATTERY

GO BACK AND READ ABOUT FUSIBLE LINKS, AT SOLENOID STUFF--CAN YOU TEST VOLTAGE ON EITHER SIDE OF THEM?

DID YOU HOOK UP THE SOLENOID >JUST LIKE MINE?

COME ON, NEED A REPLY!
