1990 YJ-no power, no cranking

So first off, I am new to working on vehicles. And I don't know much yet. But everyone needs to start somewhere!

I have a 1990 YJ that I LOVE! However, today while driving it suddenly turned off. Checked the battery and its fine. When you turn the key there is no sound or lights. It doesnt even try to crank or make any attemt to start up for me! The blinkers still work so I know its getting power. Its a straight 6 and a standard. I would completely love any help in figuring out what happened.

Passenger side below the battery is a solenoid. Sounds like you have melted some fuseable links there. They all connect to one post on the relay so some may be good and others not. This is where I would look first.

Clarissa, the fuseable links are a good place to start. I know this is going to sound perv but it is for real. You need to do the Nutter on your Jeep. It is a mod that bypasses all the emissions bs and the computer on your Jeep and will make it much more reliable. You do the mod only if the state you are in doesnt require emissions testing but it will save you so much headache and heart ache in the future by making it much more reliable and giving you better power. Best part is it is free and easy to do. Repair the current issue with the link and if you want I will post the link for the Nutter. It takes about 1 hr. from start to finish.

If it is the fusible links, just replacing them won't fix it. Fusible links are just old fashioned low tech fuses. You need to find out why they blew in the first place or it is just going to happen again.

Also, check all the grounds and if they don't look new, go ahead and replace the battery cables.

The thing they are calling the solenoid is actually called the "starter relay" most places. The solenoid is technically the thing attached to the starter. To find the starter relay, follow the smaller of the two positive battery cables.

Makes life a lot easier if you move it up higher on the firewall.
