No Power At All, Nothing, Nada!

My 84 CJ7 has no power at all. No lights, no dash, no crank. I had the battery tested and it registered 12 volts, they also put it on the charger for another 30 minutes. I replaced the battery terminals and still nothing. Prior to having the battery tested, I tried to jump it with the same result, one exception though. At one point it fired right up. After stalling out it died and back to no power at all, anywhere. Prior to this happening, it was running and starting with no problems.

Please help!

Check and clean all battery cable grounding locations! Scrape, file, wire brush to clean down to "bare" metal. If that doesn't fix it, check battery cables for corrosion, breaks and replace as needed.

On the starter relay ('solenoid') you will find the battery cable goes in one of the large terminals.

On that same large terminal, you will find two smaller (10 Ga.) Wires hooked up there.

Now, the first 5" or so of those wires is a FUSIBLE LINK,
A type of wire that acts like a fuse to protect the wires they are connected to.

What I want you to do is 'TUG' on the wires, watching the last 5" or so...
DON'T YANK THE WIRES! JUST TUGGING IS ALL IT TAKES TO CHECK THEM!

If the wire 'Stretches', you have a bad fusible link.

One of those wires goes to the back of the alternator,
The other goes to the fuse block and provides power to EVERYTHING BUT the alternator...

My guess is you have a broken Fusible Link and your fuse block isn't getting any current,
But every once in a while, you get enough connection to run things for a few minutes.

One way to test this is...
Take a small piece of wire (4" or so),
Strip both ends, and jump from the battery cable connection to the small terminal on the solenoid with the 'Blue' wire.
(MAKE SURE THE VEHICLE IS OUT OF GEAR!)

If the engine 'Cranks', you are up to about 99.9% chance it's the fusible link that is the 'Issue'...

Ok, thanks for the advice. I replaced the battery cables and made sure that the contact point is clean. I also tested the fusible link as recomended. I replaced the starter solenoid and still have nothing. No headlights, no crank, nothing.

Any other ideas are greatly appreciated.

Thanks again,
Kevin

Time to start probing with a test light. I burned the main wire on a header once at the ing. module on the left fender. That large wire supplies everything inside. Probe where that wire passes through the fire wall. Not sure if that wire has a circut breaker or not.

Terminals or cables? You use both words when saying 'replaced'?? Cables have two ends that both need cleaning, especially the end at the engine block.

Kevin:

Time to try JH advice as he stated above:

Take a small piece of wire (4" or so),
Strip both ends, and jump from the battery cable connection to the small terminal on the solenoid with the 'Blue' wire.
(MAKE SURE THE VEHICLE IS OUT OF GEAR!)

By doing this you bypass all the vehical wiring to see if the starter will engage by just energizing the starter relay ( solenoid).

Let us know if the engine will turn over with this simple test.

I'll bet it is the 10 gage wire with the fuseable link that is fried like JeepHammer has already suggested.

I had the exact same problem with a Ford truck and they use the same wiring setup as Jeeps.

It was a heavy yellow wire if I am not mistaken that comes off of the alternator. That wire powers the entire fuse block.

He says he tested the fusible links, but still a possibility

If he has battery power at the fuseblock than the link should be good. I wonder if his headlights some on?

You can't test a fuseable link just by tugging on it. Mine link was fine, but the terminal was pretty corroded.

Take a test light with a sharp point or a multimeter, pierce the insulation on the wire and test both sides of the link.

I'd be willing to bet you don't any power on the side opposite the alternator.

Remove the fusable links and throw them over your left sholder!!!!! Then replace them with 20amp breakers. Now go to the point where your harness passes through the fire wall ,if it is socketed (a plug) remove the center bolt that holds the plugs together unplug the socket and look at all the goo..... clean all the goo of all the contacts (take your time and do a good job) grease everything with a good quality contact grease. reintall plug then try to watterproof the whole aperatis. This is one ov the most overlooked problem with manny jeeps.Mine is encapsulated with a tupperware box..........Boxcar

At the risk of over-simplifying, you might want to yank the battery out of your other car, or a friends, whatever, and give it a try. Just because it measured 12 volts doesn't necessarily make it good, and if it is fried, then charging it for 30 minutes won't make it better. Easy enough to try a known good battery, just in case...

12.V is not a good reading on a auto battery... they should read 12.5 to 12.8 or so. So not a good sign.

Changing battery terminals is not always a good solution. The rest of wire could be crud and you may never see it. The CJ has very poor gounds and it causes lots of starting and failures.

JeepHammer has lots of knowledge on this subject and would encourage you to follow his suggestion.

Here are some posts on battery cables and aux grounding. I suggest you do it all.
